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 for the additional zone. It is only possible for the
system to have EITHER preferential kWh rate power
supply OR a safety thermostat for the additional zone.
# 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)
[9.8.2] [D-00] Allow heater: Which heaters are allowed
to 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] Allow pump:
▪ 0 No: Pump is forced off
▪ 1 Yes: No limitation
Do NOT use 1 or 3.
