Power supply with power-OFF: Without on-site load disconnect
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 remains
operational during the power-OFF period.
Note
Observe the technical connection conditions of the rel-
evant power supply utility.
