Priorities (for systems with a domestic hot water tank)
# Code
N/A [5-02] Space heating priority.
Defines whether domestic hot water is
made by booster heater only when
outdoor temperature is below space
heating priority temperature. It is
recommended to enable this function to
shorten tank heating operation time
and guaranteed domestic hot water
comfort.
▪ 0: disabled
▪ 1: enabled
[5‑01] Equilibrium temperature and
[5‑03] Space heating priority
temperature are related to backup
heater. So, you must set [5‑03] equal or
a few degrees higher than [5‑01].
N/A [5-03] Space heating priority temperature.
Defines the outdoor temperature which
below the domestic hot water will be
heated by booster heater only.
Range: –15°C~35°C (default: 0°C).
N/A [5-04] Set point correction for domestic hot
water temperature: set point correction
for the desired domestic hot water
temperature, to be applied at low
outdoor temperature when space
heating priority is enabled. The
corrected (higher) set point will make
sure that the total heat capacity of the
water in the tank remains
approximately unchanged, by
compensating for the colder bottom
water layer of the tank (because the
heat exchanger coil is not operational)
with a warmer top layer.
Range: 0°C~20°C (default: 10°C).
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.

[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
[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
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
operation. Therefore, always enable
the auto restart function.
▪ 2: The refrigerant part of the outdoor
unit is connected to a preferential kWh
rate
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
operation. Therefore, always enable
the auto restart function.
[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.

Average timer
The average timer corrects the influence of ambient temperature
variations. The weather-dependent set point calculation is done on
the average outdoor temperature.
The outdoor temperature is averaged over the selected time period.
