Desig. Details
Implausibly low current at the current probe or fault on the
inverter board at compressor start (can occur with compressor
damage)
Missing phase conductor on the compressor
Overcurrent fault (primary side) - check power supply / fuse
for the EMI board
Compressor overtemperature (OLP). Probe value greater than
115°C (below 12.7 kohm). Can be caused by a jammed
expansion valve
Refrigerant quantity / refrigerant loss malfunction
Power ratings for the com. kit board (IM) and the motherboard
(AM) differ - check board versions.
S06 Open contact - 2. mixed heating cycle return flow temp.
S06 Short circuit - 2. mixed heating cycle return flow temp.
The temperature difference when the heat generator is active
is implausible
Communication between operating unit SMT 1 and power unit
SMT 1 I/O was interrupted.
Desig. Details
The collector temperature is at least 60K higher than the
storage tank temperature
A collector temperature of at least 45°C (113 °F) occurred
overnight
The flow rate has dropped below the target flow rate
Low pressure. The compressor is disabled temporarily
The active operating mode is safety mode because the com-
pressor is active without demand
Compressor start error
EVD EVO probe fault
Driver offline
Device offline - please check the data connection between the
controller board and the inverter
The anti-freeze protection function is currently active - check
the room climate mode set
The hot water storage tank set temperature was reduced due
to low outside temperatures
