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.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.
