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. Thus, the
preferential kWh rate power supply OR a safety
thermostat.
4.4.4 To connect the backup heater power
supply
WARNING
The backup heater MUST have a dedicated power supply
and MUST be protected by the safety devices required by
the applicable legislation.
CAUTION
To guarantee the unit is completely earthed, always
connect the backup heater power supply and the earth
cable.
The backup heater capacity can vary, depending on the indoor unit
model. Make sure that the power supply is in accordance with the
backup heater capacity, as listed in the table below.
