ELECTRICAL ADDITION - MAXIMUM OUTPUT
Number of steps, maximum electrical power and supply on
connection for the immersion heater varies depending on
model, see tables.
The electric additional heat may be restricted depending on
the selected country.
The immersion heater’s power is set in menu 7.1.5.1 - "Int
elec add heat".
Power steps of the immersion heater
The table(s) displays the total phase current for the immer-
sion heater.
In addition to this, there is the current for compressor oper-
ation.

When the current sensors are connected, S1155PC monitors
the phase currents and allocates the power steps automat-
ically to the least loaded phase.
NOTE
If the current sensors are not connected, S1155PC
calculates how high the currents will be if the rel-
evant power steps are added. If the currents are
higher than the set fuse size, the power step is not
allowed to cut in.
