Power-OFF without on-site load disconnection
The power-OFF signal is connected
directly to the heat pump control unit.
The compressor is "forced" off when
power-OFF is enabled.
Parameter
"Output for instant. heating
water heater at power-OFF 790A"
determines whether and at what stage
an instantaneous heating water heater (if
installed) remains operational during
power-OFF.
Note
Observe the technical connection condi-
tions of the relevant power supply util-
ity.
