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 in the heat pump
control unit. The compressor
and
instan-
taneous heating water heater (if instal-
led) are "forced" off when power-OFF is
enabled.
The instantaneous heating water heater
cannot be switched on during power-
OFF; parameter
"Output for instant.
heating water heater at power-OFF
790A"
has no effect.
Note
Observe the technical connection condi-
tions of the relevant power supply util-
ity.
