# Code Description
[9.8.1] [D-01] Connection to a Benefit kWh power 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.
▪ 3 Safety thermostat : A safety thermostat
is connected to the system (normal closed
contact)

operate during preferential kWh rate power
supply?
▪ 0 No : None
▪ 1 Only BSH : Booster heater only
▪ 2 Only BUH : Backup heater only
▪ 3 All : All heaters
See table below.
Setting 2 is only meaningful if the preferential
kWh rate power supply is of type 1 or indoor unit
is connected to a normal kWh rate power supply
(via X2M/5‑6) and the backup heater is NOT
connected to the preferential kWh rate power
supply.
[9.8.3] [D-05]

[D-00] back to 0, as the system does not have a booster heater. Only set [D-00] to
the values in the table below:
