■ The
heat pump control unit/PCB
supply must be made
without
block-
ing by the power supply utility; tariffs
that are subject to possible shutdown
must not be applied to these supplies.
The power supply to the heat pump
control unit (3 x 1.5 mm
2
) and the cable
for the power-OFF signal can be com-
bined in a 5-core cable.
■ Protect the power supply to the heat
pump control unit with 16 A max.
■ For accessories and external compo-
nents that are not to be connected to
the heat pump control unit, we recom-
mend making the power connection
via the same fuse/MCB, but certainly
with the same phase as the heat pump
control unit.
Connection to the same fuse/MCB
provides additional safety when the
power is switched off. Observe the
power consumption of the connected
consumers (see from page 47
onwards).
Connecting heat pump control unit power cable (230 V~)
Note
This supply must never be blocked.
■ Recommended power cable:
3 x 1.5 mm
2
■ Max. fuse rating 16 A
■ Standard tariff (no optional economy
tariff with power-OFF)
