14.4. Alarm THERMAL
Appears if the temperature in the pellet container or
the water temperature in the appliance-s heat ex-
changer is too high.A specialist must always be used
to analyse the cause and reset the safety tempera-
ture limiter.
Possible causes:
•
The power of the convection fan is too low. Not
enough heat is channelled to the installation
room.
Increase the speed of the convection fan in
the MAXIMALE menu (Section 10.4.11)

•
Connecting hose from the pressure cell to the
waste gas collector is faulty, kinked or not con-
nected
•
The combustion air supply is obstructed
14.6. Alarm PELLET TEMP.
This occurs if the temperature of the pellet sensor
reaches a temperature that is too high.
The cause analysis must always be conducted by a
specialist.
Possible causes:

the highest power setting.
Reduce the pellet quantity in the MAXIMALE
menu "(section 10.4.11)
