Power supply with power-OFF
Power-OFF without on-site load disconnection
The power-OFF signal is connected
directly to the heat pump control unit.
When power-OFF is enabled, the com-
pressor is "forced" off, and in the 2-stage
version (type BW + BWS),
both
com-
pressors are switched off.
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.
