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.
