Preferential kWh rate power supply
#
Code
Description
[A.2.1.6]
[D‑01]
Connection to a preferential kWh rate
power supply:
▪ 0 (default): The refrigerant part of the
outdoor unit is connected to a normal
power supply.
▪ 1: The refrigerant part of 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: The refrigerant part of 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.

Which heaters are allowed to operate
during preferential kWh rate power
supply?
▪ 0 (default): None
▪ 2: Backup heater only
See table below.
Setting 2 is only meaningful if the
preferential kWh rate power supply is of
type 1 or the hydro part of the outdoor
unit is connected to a normal kWh rate
power supply (via X3M/5+6) and the
backup heater is NOT connected to the
preferential kWh rate power supply.

Power saving function
Defines whether the power supply of the refrigerant part of the
outdoor unit can be interrupted (internally by Hydro part control)
during stand-still conditions (no space heating/cooling). The final
decision to allow power interruption of the outdoor unit during
standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E‑08] needs to be
enabled on the user interface in combination with the removal of the
power saving connector at the outdoor unit.
NOTICE
The power saving connector at the outdoor unit shall only
be removed when the main power supply to the application
is switched OFF.
