If the system water pressure of your Ferroli Boiler is incorrect, it could be too high or too low. If the pressure is too high, check the system, the safety valve, and the expansion tank. If the pressure is too low, fill the system and check the sensor.
Why is overtemperature protection activating on my Ferroli ATLAS D ECO UNIT Boiler?
If the overtemperature protection is activated in your Ferroli Boiler, it could be due to a damaged heating sensor, in which case you should check its positioning and operation. It may also be caused by no water circulation in the system, so you should check the circulating pump. Another cause could be air in the system, so vent the system.
What causes a flame present signal when Ferroli Boiler burner is off?
If your Ferroli Boiler shows a flame present signal when the burner is off, it could be due to a photoresistance short circuit, in which case you should replace the photoresistance. Alternatively, extraneous light might be striking the photoresistance, so eliminate the light source.
Why is the circulating pump in my Ferroli ATLAS D ECO UNIT blocked due to external causes?
If the circulating pump of your Ferroli Boiler is blocked due to external causes, it might be due to overvoltage (>270V) or insufficient voltage (
What to do if delivery sensor 1 is faulty on my Ferroli ATLAS D ECO UNIT?
If there is a fault with delivery sensor 1 on your Ferroli Boiler, it could be that the sensor is damaged. Check the wiring or replace the sensor. Other causes can be wiring shorted or disconnected.
What to do if the DHW sensor is faulty on my Ferroli Boiler?
If there is a fault with the DHW sensor on your Ferroli Boiler, it could be that the sensor is damaged. Check the wiring or replace the sensor. Other causes can be wiring shorted or disconnected.
What to do if delivery sensor 2 is faulty on my Ferroli ATLAS D ECO UNIT Boiler?
If there is a fault with delivery sensor 2 on your Ferroli Boiler, it could be that the sensor is damaged. Check the wiring or replace the sensor. Other causes can be wiring shorted or disconnected.
Why is the circulating pump in my Ferroli ATLAS D ECO UNIT blocked due to internal causes?
If the circulating pump of your Ferroli Boiler is blocked due to internal causes, it could be that the motor is blocked or the electronics are damaged. In either case, replace the pump.
How to fix a heating sensor fault in my Ferroli ATLAS D ECO UNIT Boiler?
If there is a heating sensor fault in your Ferroli Boiler, it could be that the sensor is damaged. Replace the sensor.
What causes an external probe fault in a Ferroli Boiler?
If there is an external probe fault in your Ferroli Boiler, it could be that the probe is damaged or the wiring is shorted, so check the wiring or replace the sensor. Another cause can be that the probe was disconnected after activating the sliding temperature, so reconnect the external sensor or disable the sliding temperature.
