# Code Description
N/A [C-01] If there is a simultaneous demand for
space heating/cooling and domestic hot
water heating (by heat pump), which
operation mode has priority?
▪ 0: The operation mode with the
highest request has priority.
▪ 1: Always space heating/cooling has
priority.
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
failure. Therefore, it is recommended to always enable this function.
If the power supply might get interrupted (e.g. preferential kWh rate
power supply), always enable the auto restart function. Continuous
control of the hydro part of the outdoor unit can be guaranteed
independent of the preferential kWh rate power supply status, by
connecting the hydro part of the outdoor unit to a normal kWh rate
power supply.
# Code Description
[A.6.1] [3‑00] Is the auto restart function of the unit
allowed?
▪ 0: No
▪ 1 (default): Yes
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.
# Code Description
[A.6.2.1] [D‑00] Which heaters are allowed to operate
during preferential kWh rate power
supply?
▪ 0 (default): None
▪ 1: Booster heater only
▪ 2: Backup heater only
▪ 3: All heaters
See table below.
Settings 1, 2 and 3 are 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 and booster heater are
NOT connected to the preferential kWh
rate power supply.
[D‑00] Booster heater Backup heater Compressor
0 (default) Forced OFF Forced OFF Forced OFF
1 Permitted
2 Forced OFF Permitted
3 Permitted
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 nor domestic
hot water demand). 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.
