Benefit kWh power supply
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.
# Code Description

supply or a Safety thermostat
▪ 0 No: The outdoor unit is connected to
a normal power supply.
▪ 1 Open: The outdoor unit is connected
to a 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.
▪ 2 Closed: The outdoor unit is
connected to a preferential kWh rate
power supply. When the preferential
kWh rate signal is sent by the
electricity company, the contact will
close and the unit will go in forced off
mode. When the signal is released
again, the voltage-free contact will
open and the unit will restart
operation. Therefore, always enable
the auto restart function.
