How to set up and adjust a Ferroli gas boiler

Ferroli Diva boiler f. After firing up, some kind of noise appears, but then disappears. What is the reason? In operation for two years. There was no such noise before.

We recommend calling a specialist to determine the cause of the noise. There may be several reasons, including lack of maintenance.

Ferroli divatop 60 atmospheric with a boiler. What is anti-clock mode and how can I adjust it? It fires for no reason every 2 minutes.

Anti-clock mode is used to prevent frequent switching on / off of the unit. If you cannot configure the equipment yourself, we recommend contacting a specialized organization.

If possible, please consult on this issue. Ferroli Fortuna pro 24f. It doesn't matter what the temperature of the coolant turns on, works for 2-3 minutes, turns off and then turns on. It does not work for long, it turns off for a few seconds and immediately turns on. At the same time, it does not gain set temperature... We changed temperature sensors, changed boards and more than one. In general, only the gas valve and piezo ignition (electrode), which is also a flame sensor, have not yet been touched.

There may be a problem with the smoke exhaust system.

Should the Ferroli Fortuna boiler respond to the opening of the cold water tap?

The double-circuit unit turns on to prepare hot water when the flow sensor is triggered. Therefore, when turned on, only cold water(without hot mix) it should not turn on.

Do I need to buy a boiler with a power reserve?

The power required for heating depends on the area of the room and its heat loss. When choosing equipment, take into account weather conditions climatic zone, while using the average temperature. Users are worried about whether the unit will have enough capacity if there are severe frosts in winter. It is recommended to add no more than 20-25% to the calculated indicator. Excessive excess increases the number of switching on and off the boiler. The user will not constantly use it at full capacity. This means that the equipment will operate with low efficiency, more fuel will be consumed.

Why do you need a pump for a heating boiler?

The heating system can be built in two ways: with natural or forced circulation of the coolant. Heated water naturally moves upward, cooling down, it moves down the pipes. The advantage of such heating is energy independence. The disadvantage is the low pressure of the coolant in the system, therefore there are restrictions on the length of the pipeline. Forced
circulation occurs due to the movement of water using a pump. With it, the system can be built in any home. It is more efficient due to the high circulation rate of the water. Heating of the premises is faster and more uniform. Heating is easier to install, since a variety of wiring schemes are allowed, expansion tank can be installed anywhere. During operation, the pump consumes
electricity. If it is turned off, circulation will stop.

We want to buy a Ferroli gas boiler for installation, but we cannot choose between two models: Domina N and Fortuna F. How do they differ from each other?

Fortuna models are wall-mounted boilers with an open combustion chamber. They also come with a set of pipes for a separating smoke exhaust system. It should also be noted that they have a reduced noise level.

There is a boiler for a private house Diva F16 with a ROMEO control panel connected to it. The remote control is set to a temperature of 23C, and, in principle, the unit keeps it. But I don't like his work itself. When the temperature in the system is 23.1C, for some reason the burner turns on and it heats up to the set 65 degrees. Extra clockings are clearly present. Observations have shown that heating takes a very short time (2-0-30 seconds), and it works for itself through the bypass pipe (water does not enter the system). But if in the rooms the temperature drops to 22.8C, then the heating and work goes as expected. Why it happens?

I would like to know what quality the Ferroli Fortuna F24 pro gas boiler has. We have heard that they may have noise and rattling during operation. Is it so? And if so, is it possible to reduce it by installing the chimney according to a separate scheme. Or is it worth paying attention to some other model? And another question: do you need a voltage regulator? If necessary, tell me its power.

We would recommend you to buy a Ferroli Diva F 13-16-20-24 kW (you can choose any power, as it is adjusted on site). And at the expense of the stabilizer - look at the voltage of the incoming network. If there are jumps, then it is better to install. We also recommend paying attention to the Arena model. It differs from Diva only in control (no display and control of rotary encoders).

Repair and maintenance of the Ferroli Domina N wall-mounted boiler was required due to the fact that it does not see the opening of the contacts on the thermostat. Reboot doesn't help. It works as it did by maintaining the temperature that was manually set. When connecting, I had to install a jumper, since he did not want to start due to attempts to track the readings temperature sensor... Now there is
the need to restore this function. What should I do?

Remove the shroud and note the terminal box to the right of the board. Find there two white wires attached to the board. There, from below, they must be connected by wiring - this is the very jumper. A thermostat can be installed instead. If you have two terminal blocks available, then one of them is for outside temperature... Look for exactly the one where there is extra wiring.

I decided to do Maintenance heating boiler Ferroli Diva C 32. Reason: during secondary heat exchanger two gaskets of four flowed down. After examination, I was left puzzled technical solution: why only 2 bolts are installed on all four gaskets. I tried to tighten them, but it didn't change anything. And even at the beginning of the cycle, when heating is in progress, the unit emits an incomprehensible loud noise.

This problem happens on other models as well. The reason is an unidentified mixer. Parsing the water went through ball valve, and the pressure in the system is 4 atm. If the tap was cut off abruptly, then a water hammer occurred. In your case, installing mixers will help to limit the flow rate.

Tell me how the pressure in the system is measured with a gas wall-mounted boiler Ferroli Domina N, and also, more importantly, is its transmission over the OT interface implemented in it? This is why I need it. I have installed the OpenTherm interface. It is set to a pressure of 1.4 bar. When I add water or there is a drop in pressure in my system, the pressure gauge is working correctly. As I understand it, this may be due to rather warm weather and a rare start of the unit? But yesterday, in general, the system stopped by mistake, as the pressure became lower than the set one.

OT support is not implemented on Domina H models of the first years of release. It all depends on what the fee is. 39848640 - DBM33 control board for model F (without OpenTherm). 39848641 - DBM33 control board for model C / F N (with OpenTherm). Your boiler has a simple on / off control relay. And it reacts only to changes in the set pressure. Namely, at a pressure of 0.8 bar, a closure occurs. And from Open Therm it cannot receive anything physically, since it is not a hall sensor.

I want to private house install the boiler and the planned place of installation is basement... I originally chose gas model with a closed chamber and coaxial chimney... But the store told me that in my case, its installation was impossible, since the top of the chimney must be raised above the ground by at least 2 meters. In my case, this is technically impossible to implement. To resolve this
situations in the store, I was asked to pay attention to the Ferroli Fortuna F24 Pro, arguing that its design will allow them to mount systems without violating the installation rules. I would like to understand why he is so good?

This model has no special design differences. This is the most common unit, which has two heat exchangers and closed chamber combustion. Working power 24 kW. There is a table that shows all the recommended distances from the place of emission of combustion products into the atmosphere through outer wall a gasified room without a vertical channel from a heating gas-using
equipment with a sealed combustion chamber and a device for forced removal of combustion products. Absolutely any hinged gas boiler can be equipped with a separate smoke exhaust system. It's just that on the model recommended to you, the necessary connections are already included in the kit.

The Ferroli Diva F24 boiler is in operation. Mounted two-pipe system 32 with bottom inlet 25. House area 52 sq. M. The unit system is filled with water. Pressure in cold system 1, and when everything heats up to 70 C, then 5. All equipment is not more than a month. The rooms are equipped with a thermostat. At first everything worked fine, but recently the following problem appeared. When heating from 54 to 70, an extraneous sound appeared, somewhat reminiscent of the sound of a boiling kettle. Moreover, it is present only when the burner is operating at medium modulation. If you reduce the power of the flame, then there is silence. I tried to bleed the air, reduced the power of the entire heating system - it did not help. The water entering the unit is very hard (determined by inner walls ordinary teapot - they are all covered with scale). The filter that protects against dirt is installed only on the return pipe, but it is clean, I have already examined it. The installation and installation of the boiler was done by a specialist, but he did not adjust the pressure on the burner. Really for such short term clogged heating radiator?

The first thing you should do is adjust the gas valve. If you are convinced that everything is in order there, and the problem persists, then do the following: Focusing on the display, reduce the power in test mode to 70 degrees; then (if the sound persists) you can temporarily remove the diaphragm (43 mm in diameter) from the chimney. If all these manipulations do not help, then you will have to change
heat exchanger.

With the help of specialists, I made the connection and installation of the Ferroli Domina N gas boiler. It has been in operation for two winters and it is making me happy. For all the time of work, not a single mistake. But now there is a need to increase the heated area by 50%. As I understand it, all similar devices are structurally the same. Can I reset my 16 kW unit to 24?

Yes, you can do it. In your case, you just need to reset the heating power by parameter P06 in the control menu. Perhaps the setting is carried out in the TEST mode.

I installed a Ferroli Diva F24 boiler (power 24 kW). This power is enough for me in abundance. I wanted to buy a less powerful system (16 kW), but when buying, the seller discouraged and recommended taking with a margin, so that it would be enough for DHW heating... Already sorting out at home, I realized that all parameters are subject to adjustment. The first thing I did was set the minimum and maximum pressure values. Then, using
programs, set the maximum power limit. I set it to 12 kW. But the hot water supply still continues to consume 24 kW of power.

All models of this type have a special service menu. Working in it, you need to find the parameters P06 and P12. Parameter P06 is responsible for the maximum power consumption by heating, and P12 regulates the water supply. All parameters are set and displayed as a percentage. If you have not changed anything, then according to the factory settings, it is set to 100%. These parameters are controlled independently of each other. That is, if you reduce the value of DHW, then the power supplied to heating will remain unchanged and vice versa. It is important to return all boiler settings to the factory settings before manipulating these parameters. Only in this case will we be able to understand exactly what value we are setting. For example, the standard power of the unit is 32 kW, and it reaches its maximum value when the system pressure is 12 mbar. After that, the problem is solved simply by 32 - 100%, therefore, for example, 80% is 25.6 kW.

I'm having trouble feeding hot water... In this mode, the Ferroli DivaTech gas boiler is fired up only the second time. After the first ignition, the flame must go out. I studied the instructions for use, namely the section on cleaning the electrode, but did not find instructions on how to carry out this event. I decided that cleaning with a piece of alcoholized cotton wool would be the right decision... It did help in part, but not completely. Than in service centers this electrode is cleaned. And yet, earlier, when I watched the ignition process, I noted that the spark always strikes from one point and in the same place. And today the first few sparks flew out as standard, and the next ones were from the sides of the electrode. Is this the correct way to work? When I turn on the hot water supply, there are no problems with ignition, but a slight pop is heard. When I started a stopped and cold (it stood for about 10 hours) unit at -25C, it started up smoothly and without any extraneous sounds. I immediately got involved in the work. Before that, I cleaned the electrode like this, there were problems with starting every second time, and after that not more often than once a day.

There is a popping noise due to the very weak electric arc. You just need to clean the electrode one more time. Also remember that the gap needs to be set on a well-heated electrode. If this condition is violated, damage is possible.

In the presence of a gsm-module with a thermostat and a sensor that measures the temperature in the room. It has the function of controlling parameters via SMS, by closing and opening a contact. Can it work with the Diva f13 gas boiler (if I'm not mistaken, then the connection is made through the terminals for the remote control). What kind of remote control can be connected to it (is ROMEO suitable for wired)? Is the burner flame regulated?
established room thermostat, if so, by what principle?

Yes, in your case, you can use both a wired and a wireless remote control. However, modulating the burner flame is only possible with the installation of the ROMEO wireless remote control. See Open Therm. However, if the DBM32 board is installed on the Diva model, then work is possible only with wired consoles. On modern versions, the DBM32A board is already installed, which allows you to choose the type of connection
ROMEO. Also note that if an OSCAR thermostat is installed, then the OpenTherm protocol cannot be enabled.

I am choosing a gas boiler for a private house and I tend to think that the Diva F24 will suit me. I do not need a unit of such power, but as I figured it out, it can be adjusted according to needs by setting the maximum gas supply. That is, having bought it for 24 kW, I can use it as 16. Moreover, they are at the same price. I would like to understand what then the differences between the Divatop and the simple Diva in terms of quality and service life. Connectivity additional equipment are not important to me.

The main difference is the lack of individual firmware. We recommend taking any device of the Diva series (power from 11 to 24 kW). But be sure to install and connect the boiler so that it works for heating as 13 kW (optimal for your area), and for DHW as 24 kW.

It is required to repair the Ferroli Divatech gas boiler. Problem: ignition is delayed. Is there any way to fix this?

You have two bullet solutions to the problem. Pressure setting. Cleaning the electrode itself. You may need to do both. Also check the "electrode-board" circuit, you can still clean the heat exchanger itself. It would also not hurt to check the chimney, since in the warm season, the draft always deteriorates.

The Ferroli Diva F24 gas boiler has broken down. For repair, specialists from the service center were called. After examining them, the conclusion was that the board was faulty and replacement was required. Bought a new DBM32 board. While I was reading the instructions, everything was simple and clear. I did everything as it was written there, however, when I tried to start the unit, error 04 appeared, indicating an incorrectly configured board. At attempts to start, the noise of the fan turned on is heard, but ignition does not occur. Errors F 05 also appear (problems with the air relay). When setting up, I set the following parameters: b01 - 0, b02 - 2, b03 - 0, p16 - 0. After the third start attempt, appeared new error A015, and the boiler is blocked. I could not find what this error means. Tell me where did I go wrong?

You installed correct settings, which means that your problem is not at all with the board. Consider error F05, it denotes a problem in the dum removal system. We must look at the pipes themselves. A malfunction of the manostat is also possible. You can also check the presence and need of a diaphragm. The initial incorrect installation of the chimney is possible, and the tightness in it is broken. It is also possible to have
condensation in the monostat tube, or poor connection. There may be a problem with the fan due to its breakdown or too low voltage in the network. If you have an old model manostat, then the problem is probably in it, they often fail. By the way, errors F04 and F05 on the same unit cannot appear at the same time.

Possible errors and causes of occurrence

This article contains all possible malfunctions and options for their elimination, as well as error codes for Ferroli boilers. All information is read in next order: code - name - possible malfunction. If you have any additional questions, please leave them in the comments to this article.

Error A01 - There is no signal about the presence of a flame.

Find out the price and buy heating equipment and related products you can contact us. Write, call and come to one of the shops in your city. Delivery throughout the territory of the Russian Federation and the CIS countries.

The number of ignition attempts is assumed, which directly depends on the type of combustion chamber and the gas used.

Error A02 - False signal about the presence of a flame.

If the burner is off, and the flame monitoring system within 20 sec. finds the ionization current, then the automation of the Ferroli boiler fixes the error. If there are currently no requests to ignite the burner, the torch icon flashes, if there is a request, the icon is on.

Error A03 - Ferroli boiler overheating.

The error occurs if the emergency thermostat overheats. If at the moment of overheating the burner does not work, an error will not occur.

The temperature of the emergency thermostat is more than 105 C (if there are no requests for ignition at the current time, the error is not recorded).
The burner went out due to a high temperature in the heating system (90C - in heating mode; 95C - in test and hot water mode), but the heat exchanger continues to heat up, the automation blocks the boiler, if within 10 seconds. the temperature on the protection sensor will be more than 105 C.
If the safety sensor registers a temperature of more than 105C (heating / frost protection mode), the boiler automation will count down a 30-second interval. If during this period the temperature of two sensors (the heating temperature and the emergency thermostat) does not drop to 100C, the automatics generates an error.
The boiler is blocked when there is a request to ignite the burner. If, during the occurrence of a flame, the temperature of the emergency thermostat is higher than 100 C, the automation enters a 10-second standby mode, and only then gives an error signal.

Error A06 - The flame goes out 6 times within 10 minutes.

Low pressure in the gas circuit. Check the gas inlet pressure. The nominal gas inlet pressure must be 20 mbar.

Damaged or malfunctioning ignition / ionisation electrode - Replace the ignition / ionisation electrode if necessary.

The fan blows out the flame on the burner. The fan is not working properly. Check the voltage supplied to the fan (voltage should be 220V).

Malfunction of the control board. Restart the boiler. If the error is repeated, replace the control board.

Error A09 - Defective gas valve.

During operation, the automation monitors the operation of the gas valve (checks the current). If a discrepancy is found, then a malfunction signal is generated.

Break in the gas valve supply wire. Check the gas valve wires for damage.

Gas valve defective (gas valve). Ring the gas valve coils for interturn short circuit and open circuit. The coil resistance of the modulating valve should be ≈24 Ohm, shut-off 65 Ohm. Replace the gas valve if faulty.

Error A16 - Gas valve malfunction.

If the burner flame does not extinguish within 5 seconds after the gas valve is closed, the boiler automation generates a fault signal.

Defective gas fittings (gas valve) - Ring the gas valve coils for interturn short circuit and open circuit. The coil resistance of the modulating valve should be = 24 ohms, shut-off 65 ohms. Replace the gas valve if faulty.

Error A23 / A24 - Failure of board parameters.

The value of the email parameter is set incorrectly. boards.

Error A41 - Lack of dynamics of temperature change (heat carrier or hot water supply).

Preset time interval Combustion control is carried out by measuring resistance to plans.

Error A51 - Malfunction of the air intake / smoke exhaust system.

The error occurs if the heater goes out within 10 seconds after the expiry of the control time. Before restarting the boiler, the automation maintains a pause "d4" for 5 minutes.

Error F04 - Overheating of the flue gas thermostat (Ferroli Domiproject DC).

If at the moment of boiler operation the contacts of the flue gas thermostat are disconnected, the burner immediately goes out and gives an error signal.

After 20 minutes, the microprocessor monitors the status of the flue gas thermostat. If the contact is closed, the burner will start up. If there is no contact, the boiler will remain blocked.

Pneumatic resistance in the smoke exhaust system is increased. Check the smoke exhaust system for mechanical contamination. Check the boiler draft interrupter for dirt.

Overheating of the flue gas thermostat - you need to wait for the sensor to cool down and restart it.

The thrust is overturned. When installing, consider the "wind rose" of your area.

Incorrect control board setting. When starting up for the first time or when replacing the control board, it is recommended to set the value of parameter b03. For open chamber combustion b03 = 1.

Error F05 - The fan is not connected (only in boilers Ferroli Domiproject DF).

When a request is made to ignite the burner, the control equipment checks the fan load. If the load is not detected, then after 15-20 seconds the automation generates an error. During operation and the presence of ionization, the absence of fan load leads to the immediate shutdown of the discharges for the ignition of the burner. If the connection is not restored within 15-20 seconds, then a fault signal is generated.

If an error occurs during the initial start-up of the boiler, the chimney may have been installed incorrectly.

Check the polarity of the connectors to the contacts of the air pressure switch.
The diaphragm is incorrectly selected for the boiler (the diaphragm allows to narrow the cross-section of the smoke exhaust channel). Replace the diaphragm. When choosing a diaphragm, follow the instructions for the boiler.

Error F08 - Overheating of the heat exchanger of the extract air.

When the temperature in the heating circuit exceeds 99 C (for 5 seconds), the extract air temperature sensor is triggered. The error disappears when the coolant temperature drops to 90 ° C.

The control is carried out by an overheating sensor and an extract air temperature sensor. The error is saved in the error history menu. It is not displayed on the display and Ferroli does not lead to blocking of the boiler. The error is recorded by the extract air temperature sensor.

Error F08 has the same reasons as A03, it occurs before the appearance of error A03. You can find out that the F08 error occurred during operation by going to the Hi error history menu (see the service parameters menu).

Error F10 / F14 - Short circuit or open circuit of the target of the heating water temperature sensor.

If there is a short circuit or a break in the target of the extract air temperature sensor (the signal disappears for 3 seconds), a command is sent from the control board to turn off the burner.

Check the resistance of the semiconductor sensor. Nominal resistance of the sensor at room temperature~ 10 kOhm.

Short circuit in the circuit "Heating air temperature sensor - control board", if necessary, replace the sensor.

No signal between the contacts of the extract air temperature sensor and the connector of the control board. Disconnect the extract air temperature sensor connector from the connector on the control board, and then reconnect them for normal contact.

Short circuit in the connecting cable;
Break in the connecting wire.

Error F11 - Short circuit or open circuit of the DHW sensor.

If there is a short circuit or an open circuit in the DHW temperature sensor (lasting 3 seconds). The burner will not light up only in DHW mode. The Ferroli boiler is able to continue operating in heating mode.

Error F14 - Malfunction of the safety NTC sensor of the heating circuit.

The combined extract air temperature sensor consists of 2 identical sensors, both sensors have an overheating protection function. A malfunction of one of the sensors (short circuit or open circuit for 3 seconds) entails the disconnection of the burner ignition commands. Check the resistance of the semiconductor sensor. The nominal resistance of the sensor is 10 kOhm.

Short circuit of the extract air temperature sensor. Check the quality of the connection of the connector of the extract air temperature sensor to the control board.

Error F20 - Combustion control.

The error is related to the quality control of combustion (only in Domiproject D F boilers).

Combustion control is carried out by measuring the flame resistance.

The smoke exhaust system is not working correctly.

The fan is defective or not working correctly.

Gas valve defective or not working correctly.

The low voltage in the network (alternating current) has dropped below 180 V, the boiler automation generates an error. The error is cleared as soon as the voltage rises above 185 V.

Error F35 - Current frequency error.

The control board is powered by alternating current frequency 50Hz / 60Hz. If there is a discrepancy between the selected frequency and the frequency of the current in the network, the boiler automation generates an error.

Error F37 - Pressure drop in the heating system

The pressure switch contacts opened for more than 5 seconds. The pressure in the heating circuit has dropped below 0.8 bar.

Leakage of coolant in the heating system. Check the heating system for leaks. Repair leaks and energize the system.

The extract air pressure switch is defective. Replace the extract air pressure switch if necessary.

Error F39 - Short circuit or open circuit of the outdoor temperature sensor

The error occurs if an outside temperature sensor is connected and the weather-compensated function is active. A sensor malfunction does not result in the shutdown of the burner ignition commands.

Error F43 / F41 - Activation of the heat exchanger protection.

The fault occurs both in heating and DHW modes. If, when the burner is turned on, the heating intensity of the heat exchanger is higher than that set by parameter (P15), the extract air temperature sensor will signal a fault. Burner shutdown occurs with a delay (12 s - in heating mode; 20 s - in DHW mode, 0 s - in "Comfort" mode. The error clears itself as soon as the temperature of the heating circuit sensor drops to 45 ° C.

There is no circulation of the coolant (the pipeline is clogged, the pump is faulty);
Air in the heating system;
Same reasons as A03.

Error F42 - Protection in the event of a difference in the readings of the extract air overheating sensor and the extract air temperature sensor (combined sensor)

If the difference in readings between the emergency thermostat and the extract air temperature sensor in absolute value exceeds 12 ° C, the boiler automation generates an error.

Error F50 - Malfunction of the gas valve modulation coil

If the current on the modulation coil is below the minimum threshold, or if the circuit is open, the Ferroli boiler automation generates an error.

Check the circuit Ignition / ionization electrode - control board for short circuit.
The ignition / ionisation electrode is in contact with the burner.
Control board defective - replace.

Ignition sequence

First attempt: voltage is applied to the gas valve and ignition transformer (P01).
If a flame is found, then the boiler automation starts to control the modulation. If no flame is found, then after the end of the d03 timeout, a second ignition attempt is made.
At each next start, the sequence of the automatic functions is the same as described earlier. If, upon completion of all ignition attempts, the flame is not found, the automation gives a signal about a malfunction, the error A01 lights up on the screen.
If the burner has been successfully ignited, but then the flame has gone out, then before starting the ignition again, the Ferroli boiler automation waits for about 50 seconds, d03 lights up on the screen.
If one of the burner starts was successful (the torch was found), and then the power supply to the gas valve disappeared, then the ignition must be repeated.
If there is an excess of moisture in the combustion chamber, the electrode of the ignition transformer will be shorted to ground.

During the operation of any equipment, it is important to know about possible malfunctions, how they manifest themselves. Thanks to the use of high-tech equipment, it is quite easy to detect this or that deviation. The sensors will be informed about this. No matter how reliable the Ferolli boiler is, errors can occur. In such situations, it is important to eliminate the cause as soon as possible.

Description

One of the most popular models of the company is the Ferolli Pegasus boiler. Error and malfunction messages are displayed both on the display of the unit itself and on the remote control. Errors are displayed as code. With the help of sensors, it is much easier and more convenient to determine the place where the malfunctions have occurred.

Types of errors in the Ferroli boiler

At its core, all errors in the Ferolli boiler and malfunctions are divided into two types:

critical;
non-critical.

As a result of the first type of errors in the Ferroli boiler, a complete blocking of work occurs. To restore operability, you need to eliminate the cause of the operation. After that, the system is rebooted in manual or automatic mode. This is done using a special "reset" button.

Restarting will not work if you press the button right away. Any serious error will take at least 30 seconds. Only after such a pause (designated by the D4 code) can a restart be carried out. This is one of the security points of the device.

Critical errors of the Ferolli boiler, requiring a restart, start with the letter "A", followed by the code number.

If the system detects any minor flaws in its work, then it is automatically locked and unlocked. And only in the case of repeated repetition of some kind of malfunction, electronics may require human participation. The code for such errors begins with the letter "F".

Pause

In addition to the Ferroli boiler error codes "A" and "F", there is "D". They represent different intervals. It is not some kind of malfunction.

For example, the “D3” code can be seen in between attempts to ignite the flame. This code is quite common. It denotes an interval of 50 seconds.

Ferroli boiler errors category "A"

"A01" is highlighted when the system fails to ignite or hold. This code can be caused by the following factors.

Defective electrode.
The gas valve is out of order.
Reduced ignition power.
Lack of gas.

"A02" warns of the presence of a flame when the burner is off. This signal could be caused by a defective electronic board or electrode.

"A03" is overheating protection. It should be noted that each operating mode has its own operating temperature values. In general, the system gives 10 to 50 seconds of temperature stabilization time. If at this time there is a decrease to 100 degrees, then the shutdown does not occur. The increased temperature does not lead to an error, only if the burner is not ignited.

The reason for overheating, due to which the Ferroli diesel boiler can shut down, lies in:

pump malfunctions;
lack of normal circulation;
the presence of air in the system;
sensor malfunction.

"A06" indicates flame instability. Most often, this error appears if 6 or more extinguishing of the burner flame occurred in 10 minutes of time. May be caused by low fuel pressure or clogged passages.

"A09" informs about the failure of the gas valve.
“A16” denotes a gas valve malfunction, namely gas leak in closed position.
"A21" occurs if the combustion process is not correct. Appears if the "F20" error occurs 6 or more times in 10 minutes. Leads to restart.
"A34" informs about voltage surges, increase or decrease.
"A41" error in the temperature sensor, which may indicate a malfunction of the temperature sensor. If the sensor does not register an increase in temperature as a result of the test, the boiler will be locked out.
"A51" obstruction of the flue or air duct.

Ferroli boiler errors categories "F"

"F08" indicates overheating in the system, but unlike "A03" does not turn off the boiler. The error appears when the sensor detects a temperature of 99 degrees. When the value drops below, "F08" will disappear from the display, but the record about it can be found.
"F20" check combustion. If the system detects that the combustion process deviates from the norm, then adjustment takes place. When it was not possible to adjust the combustion, the burner is turned off and an error appears. After 50 seconds, the system automatically starts up.
"F35" can indicate a discrepancy between the current frequency and the system settings. To do this, you need to make the appropriate settings and the error will disappear.
"F50" informs about improper operation of the modulation coil or an open circuit.

Unspecified faults

The absence of a programmed code does not mean that other breakdowns do not exist in nature. Does the Ferolli boiler have faults that are not included in the database? Yes, it has. To determine them, you will have to work seriously, you will need a good knowledge of all the elements of the system. Otherwise, you need to call the master.

One of the most common reasons for this is the banal closure and disconnection of the contact on sensors and any other electrical parts. Failure or lack of contact on the water pressure switch also belongs to the list of critical situations.

The work of electronics is possible only in a complex. If a sensor starts to show an incorrect value, this will affect the operation of the entire system. Upon detecting this deviation, it will shut down.

In conclusion

Diesel boilers Ferolli are one of the most reliable. The quality of materials and workmanship does not cause complaints from the most demanding users. Their use at home brings warmth and comfort to the house, and most importantly, they are quite multifunctional and capable of performing additional functions.

If in your gas boiler ferroli, there are faults, it is not necessary to immediately call the technician for repair. It is worth looking into the instruction manual and find the error code displayed on the screen. There are indicated possible reasons the appearance of this code and methods of their elimination.

Ferroli gas boiler error codes and how to eliminate them

The domiproject, diva, domina models are the most popular among users of Ferroli gas boilers. If a malfunction occurs, its code appears either on the display of the unit or on the control panel. Codes are divided into several types:

Critical - are designated by the letter "A". When they appear, the operation of the unit is completely blocked. To eliminate such an error, you must eliminate the cause of the code on the display. You can try to reboot the unit using the "Reset" button. Reboot will occur in 30 seconds.
Non-critical - marked with the letter "F". These include minor errors that the user can fix.
Pauses are coded with the letter "D" and mean the intervals between different operating modes.

Consider what codes mean what and how you can troubleshoot. Critical "A" have the following meanings:

A01 (in domina models the red light is blinking) - problems with the burner or no ignition. You can eliminate the malfunction in the following ways: check if gas comes from the gas pipeline - if not, call the gas supply company; make sure that the fuel pressure level is normal; when air accumulates in the line, their excess is drained; adjust the power.
A02 (green light is on or flashing) - message about the presence of a flame in its absence. Remedies: restarting the unit, adjusting the power, checking the electrode wires.
A03 (red indicator flashes) - overheating protection has triggered (if the temperature of the coolant rises above 105 ° C, then the equipment is turned off). This error appears if the temperature has not returned to normal within 50 seconds. Restart the gas boiler. If the unit still does not turn on, then you need to take the following measures: replace the main module, check the overheating sensor, diagnose the operation of the pump, release excess air, check the fluid circulation, check the connection to the mains.
A06 - unstable flame. The problem can be eliminated by the following methods: readjust the gas supply, replace the burner diaphragm, change the ignition sensor, normalize the fuel pressure.
A09 - malfunction of the fuel supply valve.
A16 - the valve allows gas to pass when closed. The valve should be repaired or replaced.
A21 - malfunctions in combustion. The system needs to be rebooted.
A34 - voltage drops. You can solve the problem like this: install a voltage stabilizer, connect a new coolant temperature sensor.
A41 - the temperature does not rise. Tighten the sensor connectors.
A51 - the chimney is clogged. It is advisable to check the presence of a draft in the chimney: if there is one, check the operability of the draft sensor; if not, you need to clean the chimney.

Non-critical errors "F " have such codes :

F04 (green light is blinking) - smoke extraction is activated. Correct the position by stripping the contacts or replacing the smoke detectors or reconfiguring the module.
F05 - incorrect fan connection. Inspect the wiring of this item. If necessary, tighten it.
F08 - circuit temperature is above 99 ° C. The error will disappear if the heat exchanger cools down to 90 ° C.
F10 / F14 - open or short circuit of the thermistor. Eliminated by repairing or replacing a broken part.
F11 - the burner does not operate in DHW mode, as the DHW thermistor has shorted. The problem is solved by replacing the faulty theristor.
F20 - malfunctions of the electronic board. The reasons are as follows: incorrect parameter settings or board malfunction. In the first case, the boiler is reconfigured, and in the second, the board is replaced.
F34 - a malfunction of the ferroli domiproject gas boiler means a decrease in the voltage in the network below 180 V. After the normalization of electricity, the error will disappear or a voltage stabilizer should be installed.
F35 - current mismatch in the network and on the control board. Replace the existing board with a new one that matches the current frequency reading.
F37 (yellow indicator flashes) - pressure drop in the heating system. Make sure the unit is not leaking. Change the relay if necessary.
F39 - short circuit of the external thermometer, breakdown of the thermistor. The problem is eliminated by the following actions: checking the contacts, insulating the damaged wiring, installing a new thermometer.
F40 - the pressure in the heating system exceeds the norm. In this case, remove the filter relief valve and rinse it from clogging. If this part is defective, it must be replaced. You also need to check the performance of the expansion tank.
F42 - overheating sensor and temperature show different meanings... It is necessary to measure the resistance of the DHW thermistor. Normal readings are 10 kΩ. If they deviate from the norm, the element should be replaced.
F43 - the heat exchanger safety system has been triggered. Checking the operation of the circulation pump, bleeding air from the system.
F50 - malfunctions of the gas fittings. The situation can be corrected by restarting the boiler. If this does not help, the electronic board should be repaired.
Fh - air is removed by a circulation pump. Usually disappears after three minutes.

Most errors block the operation of the gas unit. In some cases, restarting the heating device solves the problem. But still, you need to find out the true cause of the failures and eliminate it. Timely elimination of the cause of the malfunction will prevent significant damage to the unit and extend its service life.

Gas boilers of the Ferroli trademark are especially widespread in the domestic market. heating appliances... Not least due to the moderate price for them, which at the same time corresponds to good quality of these products. Ferroli has been manufacturing products since 1958.

Thus, it should be assumed that all consumer novelties are reflected in the products of this brand in a timely manner. Instructions for the use of gas boilers Ferroli, which can be found below, will help you understand the application.

Features of this product line

The basis of the model range of wall-mounted gas boilers of the trademark are the Diva and Domina N units, the delivery of which has been carried out since 2013. The main specifications products of approximately the same power are shown in the table.

Such a review of Ferroli gas boilers shows that both sizes belong to the double-circuit category. These are products that provide guaranteed heating of premises up to 100 sq.m. and hot water supply.

The external characteristics of such boilers generally correspond to lineup, while their dimensions are one of the smallest among the analogues. Reviews of gas boilers Ferroli indicate primarily their compactness. Appliances can be installed even in small kitchens, which is an undoubted advantage of these products.

The low-cost design of products from the Ferroli trademark is manifested in the fact that the Diva series units are equipped with pressure control sensors - pressure switches - only optionally, like some other diagnostic devices.

It is assumed that the automation system, adjusted to certain conditions operation, itself will quickly respond to changes in pressure, pressure and other parameters that affect the normal operation of the boiler. In fact, everything is determined by the quality factor of the transportation and installation conditions.

Analysis of some design solutions

Since the market for household gas boilers is quite densely filled, there is always an opportunity to compare the main operating parameters competing boilers. In units from the Ferroli brand, the heads of the injection burners are made of of stainless steel AISI 304 (for comparison - AISI 310S steel is used in German-made boilers).

Significant disadvantages of AISI 304 steel are its inability to withstand high temperatures for a long time, as well as insufficient mechanical strength... Let us give for comparison the chemical compositions of both grades of steels indicated above, precisely from the point of view of the required durability:

Comparison chemical composition clearly shows: although formally both steels belong to the low-carbon class, the strength of AISI 310S steel is 40% higher than that of AISI 304 steel. - up to 900 ° С, and for a long time - up to 600 ° С.

There are similar questions regarding the selected material of heat exchangers: Ferroli boilers use an aluminum alloy, while similar products from Vissmann use cast iron. Although this circumstance somewhat increases the mass of the boiler, the durability of cast-iron heat exchangers is almost 1.5 times greater than the durability of aluminum ones. In some models, copper heat exchangers are used, but their strength is inferior to cast iron. This decision can be the reason for the malfunction of Ferroli gas boilers.

Burner type

The devices from the Ferroli trademark use a conventional atmospheric burner, whose parts are characterized by sharp temperature changes during operation. This provokes thermal deformation, accompanied by a change in size with the subsequent risk of microcracking. Fan burners implemented in the designs of German gas boilers operate with constant water cooling, which:

increases the service life of the burner;
reduces the emission of harmful gases into the atmosphere to the European fixed environmental standards.

Of course, the operating instructions for gas boilers Ferroli are silent about these, as well as others design features these units.

Unit capabilities

The instruction for gas double-circuit boilers Ferroli describes some of the features of the start-up process, as well as the operation of control systems. Here is the instruction manual.

To switch on, you need to open the gas valve, then turn on the power supply.
Put the knobs regulating the temperature of heating and hot water in desired position... After that, the boiler will automatically turn on when the room temperature drops or when hot water is needed.
If you turn both knobs to the minimum, the boiler will not work, but it still consumes power. This is due to the "anti-freeze" function, which includes heating the water in the heating system in the event of a strong drop in temperature. environment... In this case, the signal lamps do not light up.
By adjusting the knobs, you can set summer or winter modes.
There are three modes: Summer (only heating water for hot water supply), Winter (heating and DHW), as well as a mode in which DHW is turned off and only heating works.

It is worth knowing some of the nuances of starting the heating system. They are listed below.

The ability to work on any type of gas - liquefied and natural.
Chimney freeze protection. At the same time, the instructions contain an indication of draining water from the corresponding circuits when the boiler is not working in winter.
Electronic ignition and a microprocessor-based boiler control system are really useful technical innovations. Its implementation allows avoiding unnecessary risks in case of insufficient qualifications of the user of the heating unit.
Ferroli boilers are not supplied with shut-off valves, which increases the risk of flooding the room when the pressure in the network is exceeded, when the unit is turned off, but the coolant supply does not stop.
The process of installing adapters to chimneys is quite complicated. Instructions and photos of Ferroli gas boilers show the algorithm and sequence of replacement. But the complexity of the calculations requires calling a specialist licensed to work with these units, since some initial data are not given in the instructions.

Typical malfunctions

The above-described features also predetermine the malfunctions characteristic of the Ferroli gas double-circuit boiler. Among the most common breakdowns in people, the following can be distinguished.

The Ferroli gas boiler does not turn on - such a malfunction may occur due to the lack of gas in the network, the presence of air in the pipelines, a malfunction of the gas valve or ignition electrode.
In the Ferroli gas boiler, the water pressure drops. A malfunctioning circulation pump is the main cause. In the absence of a pressure switch (but in the presence of a coolant in the system), such a malfunction may manifest itself with insufficient ignition power, which should be increased. Damage to the electronic board of the boiler is also possible.

Many reviews mention modern design and appearance products, which is generally typical for any Italian goods. At the same time, it is indicated that the products are not highly reliable. At one time, such a malfunction of the Ferroli Domiproject F24 gas boilers became the main reason for their discontinuation. However, the quality of the new line of models is not much superior to the previous one.

Malfunctions heating systems are often repeated in new models. Reviews indicate underdevelopment service: existing specialized repair firms do not know much about the design of boilers, and optional products for them (for example, a sensor for monitoring the connection of a boiler, etc.) are very difficult, if not impossible, to acquire.

Particularly unreliable are the nodes of the circuit responsible for the operation of the water heater: electronic boards often fail, the heat exchanger is unstable, and you have to use gas cock... At the same time, prices for Ferroli double-circuit gas boilers depend on their capacity and start at 30,000 rubles.
