5. Shutoff flue gas temp. in Heating mode
too low (21)
Cause:
Temperature fell below the minimum
temperature in Heating mode operating
status
The following circumstances might lead to this:
No pellets present
The screw conveyor is not rotating, it is
jammed, the screw conveyor motor is
defective or the chute is not clear
The required combustion air cannot be
supplied to the stove e.g. via a vapour
extractor hood that is located in the
vicinity of the installation site and is
switched on.
Room too airtight
– required combustion
air cannot be replenished in the room
Suction filter dirty
Burner dirty
Poor seals on the pellet stove (door,
seals)
Flame temperature sensor defective
Flue gas temperature sensor defective
Correction:
Refill pellets
Check that the chute between the pellet
tank and the burner is clear.
Clean the burner and suction filter.
Check whether there is a vapour
extractor hood present and whether it is
in operation
Make sure for instance that a window is
left open a crack to supply the required
combustion air
Contact the service engineer
6. Shutoff flue temp. in Heating mode too
high (22)
Cause:
The highest permitted flue gas
temperature was exceeded
The following circumstances might lead to this:
Too much fuel is being supplied to the
burner
Flue gas temperature sensor defective
Correction:
Contact the service engineer
7. Shutoff, combustion chamber door open
(6) or (9)
Cause:
The door is open for longer than 1 minute
during operation
The damper at the bottom of the door is
not in the right position
Cable broken in the electric wiring to the
door contact switch
The connector has come out on the door
contact switch or on the central unit
Correction:
Close the door
Move the damper at the bottom of the
door to the right position so that the
switch is operated when the door is
closed
Check door contact switch, cable and
connector
8. Flue gas sensor interruption (7)
Cause:
Flue gas temperature sensor defective or
not connected
Correction
Contact the service engineer
9. Flue gas sensor short circuit (8)
Cause:
Flue gas temperature sensor defective
Correction:
Contact the service engineer
10. Room temperature sensor interruption(11)
Cause:
Room temperature sensor defective or
not connected
Correction:
Contact the service engineer
11. Room temperature sensor short circuit
(12)
Cause:
Room temperature sensor defective
Correction:
Contact the service engineer
12. Flame temp. sensor interruption (23)
Cause:
Flame temperature sensor defective or
not connected
Correction:
Contact the service engineer
