INFORMATION
In case of preferential kWh rate power supply, the
necessity of a separate normal kWh rate power supply to
the hydro part of the outdoor unit X3M/5+6 depends on the
type of preferential kWh rate power supply.
A separate connection to the hydro part of the outdoor unit
is required:
▪ if preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption by the hydro part of the
outdoor unit is allowed at the preferential kWh rate
power supply when active.
