ADVICE IN THE EVENT OF PROBLEMS
H1) Low pressure alarm (this trips if the flow sensor detects insufficient combustion air flow)
The 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 with frequency according to the type of pellet)
- smoke duct (clean)
- installation (if it does not comply with regulations or the smoke outlet has too many 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 low pressure alarm may also occur during ignition, since the flow sensor starts monitoring 90 seconds after the ignition cycle
starts.
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
- Verify functionality of the control board (Performed solely by the Dealer)
- Verify functionality of the earthing system of the electrical system
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 also be an excessive smoke temperature).
AF(H4) Ignition failed ((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:
the flame does NOT appear
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.
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 for 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.
Flames appear, but AF appears on the display
after Ar.
Check: (only for Dealer)
- if the thermocouple is working
- start-up temperature set in the parameters
- 24
