Power-OFF with on-site load disconnection
The power-OFF signal is connected to
the on-site contactor of the economy tar-
iff power supply and to the heat pump
control unit. When power-OFF is ena-
bled, the compressor
and
the instanta-
neous heating water heater (if installed)
are "forced" off, and in the 2-stage ver-
sion (type BW + BWS),
both
compres-
sors
and
the instantaneous heating
water heater are switched off.
Note
Observe the technical connection condi-
tions of the relevant power supply util-
ity.
