■ In conjunction with on-site energy con-
sumption (use of power generated by
the PV system to meet own require-
ments):
Note
During the power-OFF period, it is
not possible to operate the compres-
sor with power generated on site.
■ Protect the power supply to the heat
pump control unit with a fuse of 16 A
(max.).
■ For accessories and external compo-
nents that are not connected to the
heat pump control unit, connect the
power supply with the same phase as
the heat pump control unit, ideally
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.
