INFORMATION
In case of preferential kWh rate power supply, the
necessity of separate normal kWh rate power supply to
indoor unit (b) X2M30/31 depends on the type of
preferential kWh rate power supply.
Separate connection to the indoor unit is required:
▪ if preferential kWh rate power supply is interrupted when
active, OR
▪ if no power consumption of the indoor unit is allowed at
the preferential kWh rate power supply when active.
