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 system can have EITHER preferential
kWh rate power supply OR a safety thermostat.
