Electrical addition - maximum output
The immersion heater output is divided into steps, ac-
cording to the table.
Setting maximum output in the electric additional heat
is done in menu 5.1.12.
When switching from 3x400 V to 1x230 V, the immersion
heater is limited to 2 kW. Min. fuse rating 16 A.

The table displays the maximum phase current for the
relevant power step for the heat pump.
If the current sensors are connected, the heat pump
monitors the phase currents and allocates the electrical
steps automatically to the least loaded phase.

Output locking
F470 follows applicable building regulations (BBR). This
means that the maximum power output (maximum in-
stalled electrical output for heating) can be locked in
menu 5.1.13. To then change the maximum power out-
put, parts of the product must be replaced.
Emergency mode
When the heat pump is set to emergency mode (SF1 is
set to ), only the most necessary functions are activ-
ated.
■
The compressor and fans are off and heating is man-
aged by the immersion heater.
■
The load monitor is not connected.
