Power supply with power-OFF: Without on-site load disconnect
The power-OFF signal is connected directly to the heat
pump control unit. When power-OFF is enabled, the
compressor is "forced" off; in the 2-stage version (type
BW 301.B + BWS 301.B), this applies to
both
com-
pressors.
Parameter
"Output for instant. heating water heater
at power-OFF 790A"
determines whether and at what
stage an instantaneous heating water heater (if instal-
led) remains operational during power-OFF.
