17 Troubleshooting
39 - Solar setting Max. tank temperature bottom
can trip safety temperature limiter
The message is triggered when the parameter
Maxi-
mum tank temperature bottom
is set higher than 82°C
in the solar settings of the control. CAUTION: The bur-
ner cannot start at the next request.
40 – Ignition not possible
This message appears after two unsuccessful ignition
attempts.
Cause / action:
–
Pellet storage tank is empty / > check whether pel-
lets are being conveyed.
–
The combustion chamber or flue gas pipe to the
chimney are full of ash / > check
–
The combustion chamber door is not closed pro-
perly / > check
–
The combustion grate is covered with ash and
should be cleaned / > check
–
The combustion chamber is worn, pellets are fal-
ling through / > visual inspection inside the com-
bustion chamber / ash container.
–
Defective ignition device / > qualified personnel.
–
An auger is defective (pellet auger, tank auger, sto-
rage area auger) / > contact qualified personnel
41 - FUSE F1 or F8 defective
Fuses on the electrical power section of the boiler.
Message is triggered when the 24 V DC supply is not
available for the digital outputs; possible cause: Fuse
F1 or F8 defective.
42 - Warning! Shortage of pellets in storage area
Message triggered, if at the automatic suction probe
switching unit only two suction probes are marked as
full
(if a total of only two probes is present, then if only
one probe is still marked as
full
).
43 - Suction probe switching unit error
Communication between the boiler control and the
electronic module of the diverter for suction heads
(DFSH) is functioning, but...
Cause:
–
- One of the two switches (proximity switch, refe-
rence switch) in the DFSH is defective, or there is
a disruption, short-circuit.
–
Cabling fault between DFSH (motor, switches)
and electronic module.
–
Input/output at the electronic module is defective.
–
A fuse in the electronic module is defective.
–
The motor of the DFSH is defective.
44 - Communication error cascade
46 - The ash box is full and must be emptied
47 - Warning! Maintenance– inspection
48 - Boiler cleaning recommended
49 - Boiler door or ash box is open
Check the cladding door and the cover of the ash box
for correct seal.
50 - The boiler door is open A burner start is not
possible
Check the cladding door for correct seal.
51 - Battery in operating element is dead
A replaceable buffer batter (CR2032) ensures that data
(time, settings) are retained when the supply voltage is
switched off.
73- Error in reference switch for suction heads
During the zero point search of the diverted for suction
heads, the reference switch was not actuated by the
intended mechanism.
Cause:
–
The reference switch in the DFSH is defective, or
there is a disruption, short-circuit.
–
Cabling fault between DFSH (reference switch)
and electronic module.
–
Inaccurate position of the reference switch.
