INFORMATION
In case of preferential kWh rate power supply, connect
X6Y to X6YB. 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.
