INFORMATION
In case of preferential kWh rate power supply, connect
X11Y to X11YB. The necessity of separate normal kWh
rate power supply to indoor unit (b) X2M/5+6 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.
