10 FAULT REPORTS AND THEIR CORRECTION
You should always take particular note of the safety instructions!
For all faults arising the fault must first be rectified and then re-set by switching on again. Should several
faults arise at the same time, these are displayed in the order they arose.

Suggestions for rectifying
Fault 01
F:Checksum
X
Checksum not correct
Replace control
Fault 02
F:Adjustmentdata
HZS 621/622
X
Checksum not correct
Replace control
Fault 03
F:Adjustmentdat
HZS 631
X
Comparison of data not correct
Replace control
Fault 04
F:STL
X
Mains voltage faulty
 Safety temperature limiter
(STL) has gone off
Let the system cool off and leave
the STL.
Fault 05
F:Boiler temperature
X
Broken sensor for boiler
temperature
Replace the boiler sensor
Fault 06
F:CAN-failure
X
Failure at transmission via CAN
Bus
Check CAN-connection (Cabeling)
Fault 07
F:EEProm
X
Error at writing / reading at
EEProm
Replace control
Fault 08
F:Stack HZS 621/622
X
Overflow from the stack pointer
Replace control
Fault 09
F:Stack HZS 631
X
Overflow from the stack pointer
Replace control
Fault 10
F:Fluegas temperature
X
Broken sensor for flue
temperature PT1000
Replace flue temperature probe
Fault 11
F:Lambda calibration
X
Fault in lambda calibration
Lambda value is outside the
defined range.
Carry out calibration again or
renew the lambda probe
Fault 12
F:Suction speed
X
 Suction blower speed
monitoring fault
 false number of pulses
Check suction and speed
feedback
Fault 13
Door contact
Door is open
Information only – No failure
Fault 14
F:Ready
Boiler temperature above boiler
maximum (90°C)
 Boiler loaded with too much
wood
 Return flow pump or return
flow mixer defective
 Buffer storage construction
too small
 Put in less wood
 Renew return flow pump or
return flow mixer
 Increase buffer volumes
Fault 15
F:Lambda probe
X
Lambda probe is defective or
out of line
Renew lambda probe and /or
check clamping.
Fault 16
F:Backflow sensor
X
Broken sensor for return flow
temperature
Replace return flow temperature
