POSSIBLE TROUBLESHOOTING
In the event of problems the boiler stops automatically and runs the shutdown process and the display shows text regar-
ding the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
To start the boiler up again after a shutdown, let the shutdown procedure end (10 minutes marked by a beep) tand then
press the button 0/1.
Do not turn the boiler on again before checking the cause of the malfunction and CLEANING/ EMPTYING the crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES:
1) Signalling:
H2O PTC_FAULT
Problem:
Shuts down due to the water temperature sensor being broken or disconnected.
Actions:
- Check connection of the sensor to the control board.
- Verify functionality by means of a cold test
Problem:
Shutdown for smoke extraction speed fault detection
Actions:
3) Signalling:
Stop/Flame:
Problem:
Turns off due to drop in smoke temperature
Flame may fail for any of the following reasons:
- lack of pellets
temperature) (DEALER)
4) Signalling:
Block_FI/NO Start:
or if ignition temperature is not reached).
Problem:
Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
Flame does NOT appear
Actions:
Check: - combustion chamber position and cleanliness;
- arrival of combustion air in the combustion chamber;
- if the heating element is working (DEALER);
Flames appear, but AF appears on the display after Ar.
Actions:
Check: (only by the Dealer)
- if the thermocouple is working (DEALER);
- start-up temperature setting in the parameters (DEALER).
5) Signalling:
Black Out: (not a defect of the boiler).
Problem:
Turns off due to lack of electricity
Actions:
6 ) Signalling: Fault/RC: (intervenes if the thermo coupling has failed or is disconnected).
Problem:
Turns off due to thermo coupling failed or disconnected
Actions:
7) Signalling: smoke °C/high.: (turns off due to exceeding maximum smoke temperature).
Problem:
Spegnimento per superamento temperatura massima fumi.
Check (only by the Dealer):
8 ) Signalling: H2O TEMPALARM
Problem:
Shuts down due to water temperature being higher than 90 °C.
An excessive temperature may occur because of the following:
(this trips if the smoke extraction speed sensor detects a fault)
- 42
