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.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/3+4) as the safety
thermostat. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.
7.10.10 To connect the user interface
▪ If you use 1 user interface, you can install it at the indoor unit (for
control close to the indoor unit), or in the room (when used as
room thermostat).
▪ If you use 2 user interfaces, you can install 1 user interface at the
indoor unit (for control close to the indoor unit) + 1 user interface
in the room (used as room thermostat).
The procedure differs slightly depending on where you install the
user interface.
