DVICE IN THE EVENTOFPROBLEMS
H1) No Depression (this trips if the flow sensor detects insufficient combustion air flow)
Air flow may be insufficient because the door is open, the door does not close properly (e.g. bad seal), there is an air
intake or smoke extraction problem, or the combustion chamber is clogged.
Check:
- door closure;
- combustion air intake duct (clean, paying attention to the flow sensor components);
- clean the flow sensor with dry air (like that used for PC keyboards);
- stove location: it must not be installed against a wall;
- combustion chamber position and cleanliness (clean regularly according to the type of pellet);
- smoke duct (clean);
- installation (if it does not comply with regulations or the smoke outlet has more than 2-3 bends);
- flow sensor threshold (SF in the parameters) (only by the Dealer).
If you suspect the sensor is malfunctioning, carry out cold tests. If the conditions are changed (for example by opening
the door) and the value does not change, there is a sensor problem.
The no depression alarm may also occur during ignition, since the flow sensor starts monitoring 90 seconds after the
ignition cycle begins.
H2) Smoke expulsion motor failure (this trips if the smoke extraction speed sensor detects a fault)
- Check smoke extractor operation. (Performed solely by the Dealer)
- Check speed sensor connection. (Performed solely by the Dealer)
- Make sure the smoke duct is clean
- Check the earth connection (Performed solely by the Dealer)
SF(H3) Flame stop (this trips if the thermocouple detects a smoke temperature lower than the value set, which it
interprets as the absence of flames)
There may be no flames because:
- there are no pellets;
- too many pellets have smothered the flames;
- the maximum temperature thermostat has tripped (this is very unusual since there would be an excessive smoke
temperature).
AF(H4) No start (this trips if no flames appear and the start-up temperature is not reached within a maximum of 15
minutes)
There are two distinct cases:
H5) Power failure stoppage
Check the electrical connection and for voltage drops (the block does not depend on the stove).
H6) Thermocouple failure (this trips if the thermocouple fails or is disconnected) (only by the Dealer).
Check connection between the thermocouple and the circuit board.
Check operation with cold tests.
H7) Excessive smoke temperature (shutdown due to excessive smoke temperature)
Excessive smoke temperature may be caused by:
the type of pellet, smoke extraction fault, blocked duct, incorrect installation, or gearmotor "drift".
Err. 1 - Err. 2
The heating stove will not stop, but this message appears on the display. The buffer battery on the pcb must be replaced.
Contact the DEALER.
the flame does NOT appear Flames appear, but AFappears on the display afterAr
Check:
- combustion chamber position and
cleanliness;
- arrival of combustion air in the combustion
chamber;
- if the heating element is working;
- room temperature (if lower than 3°C use a
firelighter) and damp.
Try to light with a firelighter.
Check: (only by the Dealer)
- if the thermocouple is working;
- start-up temperature setting in the parameters.
