Connection to a preferential kWh rate power
supply or a safety thermostat:
▪ 0: The outdoor unit is connected to a normal
power supply.

preferential kWh rate power supply. When the
preferential kWh rate signal is sent by the
electricity company, the contact will open and
the unit will go in forced off mode. When the
signal is released again, the voltage-free
contact will close and the unit will restart
operation. Therefore, always enable the auto
restart function.

preferential kWh rate power supply. When the
preferential kWh rate signal is sent by the

contact will open and the unit will restart
operation. Therefore, always enable the auto
restart function.
