ID7312 WKF fault code E469
Voltage probe fault in the intermediate DC circuit of the
inverter. Replace inverter board if necessary
ID7313 WKF fault code E458
Implausibly high current at the current probe or fault at the
BLDC motor for fan 1.
ID7314 WKF fault code E475 Fault at the BLDC motor for fan 2
ID7315 WKF fault code E461
Implausibly low current at the current probe or fault on the
inverter board at compressor start (can occur with compressor
damage)
ID7316 WKF fault code E467 Missing phase conductor on the compressor
ID7317 WKF fault code E462
Overcurrent fault (primary side) - check power supply / fuse for
the EMI board
ID7318 WKF fault code E463
Compressor overtemperature (OLP). Probe value greater than
115°C (below 12.7 kohm). Can be caused by a jammed expan-
sion valve
ID7319 WKF fault code E554 Refrigerant quantity / refrigerant loss malfunction
ID7320 WKF fault code E556
Power ratings for the com. kit board (IM) and the motherboard
(AM) differ - check board versions.
ID7328
Open contact -
2nd mixed heating cycle
return flow temp.
S06 Open contact - 2. mixed heating cycle return flow temp.
ID7329
Short circuit - 2. mixed
heating cycle return
flow temp.
S06 Short circuit - 2. mixed heating cycle return flow temp.
ID7333 Negative temp. differ-
ential
The temperature difference when the heat generator is active is
implausible
ID7334 Comm. signal
Communication between operating unit SMT 1 and power unit
SMT 1 I/O was interrupted.

ID8102 Temperature discrep-
ancy in solar cycle
The collector temperature is at least 60K higher than the
storage tank temperature
ID8103 Overnight collector
temperature
A collector temperature of at least 45°C (113 °F) occurred over-
night
ID8105 Target flow rate The flow rate has dropped below the target flow rate
ID8106 Low pressure Low pressure. The compressor is disabled temporarily
ID8107 Compressor status
The active operating mode is safety mode because the com-
pressor is active without demand
ID8108 Compressor start error Compressor start error
ID8109 EVD EVO probe fault EVD EVO probe fault
ID8110 Driver offline Driver offline
