Code Description
Sensor error T5 (water temperature sensor)
Evaporator temperature sensor error T3.
Room temperature sensor error T4.
Compressor discharge TP temperature sensor error.
Compressor intake TH temperature sensor error.
Open circuit error on the immersion heater (IEH (dif­
ference in current between ON and OFF on the im­
mersion heater) < 1 A).
Protection against high discharge temperatures:
Tp > 115: Protection active.
Tp < 90: Protection inactive.
Protection against overloads on the compressor (ten
seconds after switching on the compressor, the cur­
rent overload control starts up).
1. If the compressor is running: if the current load is
> 7 A, the compressor is shut down and the pro­
tection activated.
2. If the compressor and the immersion heater are
running: if the current load is > IEH + 7, the com­
pressor is shut down and the protection activated.
Load value when the compressor and the electric
water heater start up at the same time: 14 A
(1550-W electric water heater).
