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.
