■ The heat pump control unit/PCB
must be supplied without power-OFF;
tariffs that are subject to possible shut-
down must not be used here
■ Protect the power supply to the heat
pump control unit with max. 16 A
■ For accessories and external compo-
nents that are not to be connected to
the heat pump control unit, connect the
power supply with the same phase as
the heat pump control unit; we recom-
mend using the same fuse/MCB.
Connection to the same fuse/MCB
provides additional safety when the
power is switched off. Observe the
power consumption of the connected
consumers
