ADVICE IN THE EVENT OF PROBLEMS
H1) Low pressure alarm (this trips if the ow sensor detects insufcient combustion air ow)
The ow may be insufcient 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 ow sensor components):
- clean the ow 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)
- ow 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 ow 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
- Check speed sensor connection
- Make sure the smoke duct is clean
- Verify functionality of the control board
- 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 ames)
There may be no ames because
- there are no pellets
- too many pellets have smothered the ames
- 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 ames appear and the start-up temperature is not reached within a maximum of
15 minutes).
There are two distinct cases:
the ame does NOT appear
Flames appear, but AF appears on the display
after Ar.
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 relighter)
and damp
Try to light with a relighter.
Check: (only for Dealer)
- if the thermocouple is working
- start-up temperature set in the parameters
H5) Power failure stoppage
Check the electrical connection and for voltage drops.
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”.
