Electrical addition - maximum output
On delivery, the immersion heater is connected for a
maximum of 7 kW (3x400V and 1x230V) or 9 kW
(3x230V). For 3x400V the immersion heater cannot be
switched to 9 kW.
The immersion heater's output is split into seven steps
(four steps at 3x230V or if the immersion heater for
3x400V is switched to maximum 9 kW), according to the
table below.
Setting max electrical output
Setting maximum output in the electrical addition is done
in menu 5.1.12.
The tables display the total phase current for the immer-
sion heater.
Switching to maximum electrical output
NOTE
This switch only applies to 3x400V.
If more than the maximum output for the immersion
heater connected on delivery is needed, the heat pump
can be switched to maximum 9 kW.
Move the white cable from terminal block X7:23 to ter-
minal block X3:13 (the seal on the terminal block must
be broken) on the immersion heater card (AA1).

If the current sensors are connected, the heat pump
monitors the phase currents and allocates the electrical
steps automatically to the least loaded phase.
Emergency mode
When the heat pump is set to emergency mode (SF1 is
set to ) only the most necessary functions are activated.
The compressor is off and heating is managed by the
immersion heater.
Hot water is not produced.
The load monitor is not connected.
NOTE
Switch (SF1) must not be moved to " " or "
until F1145 has been filled with water. Other-
wise the temperature limiter, thermostat, com-
pressor and the immersion heater can be dam-
aged.
