INFORMATION
Some types of preferential kWh rate power supply require
a separate normal kWh rate power supply to the outdoor
unit. This is required in the following cases:
▪ if the preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption of the hydro module of the
outdoor unit is allowed at the preferential kWh rate
power supply when active.
