Power supply with power-OFF: With on-site load disconnect
The power-OFF signal is connected to the on-site con-
tactor of the economy tariff power supply and to the
heat pump control unit. When power-OFF is enabled,
the compressor
and
the instantaneous heating water
heater (if installed) are "forced" off; in the 2-stage ver-
sion (type BW 301.B + BWS 301.B), this applies to
both
compressors
and
the instantaneous heating
water heater.
Note
Observe the technical connection conditions of the rel-
evant power supply utility.
