10 Configuration
Equilibrium temperature
Based on the ambient temperature, energy prices and the required
leaving water temperature, the user interface is able to calculate
which heat source can deliver the required heating capacity most
efficiently. However, to maximise the energy output of the heat
pump, it is possible to prevent the gas boiler from operating when
the ambient temperature exceeds a certain point (e.g. 5°C). This can
be useful to avoid too much gas boiler operation in case of incorrect
settings. When an equilibrium temperature is set, domestic hot water
operation is NEVER prohibited.
#
Code
N/A
[5‑00]
Defines if gas boiler operation is allowed
when the ambient temperature exceeds
the set equilibrium temperature during
space heating operation.
▪ 0: allowed.
▪ 1: NOT allowed.
N/A
[5‑01]
Equilibrium temp.
When the ambient temperature is higher
than this temperature, the gas boiler is
NOT allowed to work. Only applicable if
[5‑00] is set to 1.
Range: –15°C~35°C
NOTICE
In case of third-party gas boiler:
▪ To allow more heat pump operation, it is highly
recommended NOT to change the default setting of
[5‑00], and keep the value at "1".
▪ If there is a capacity shortage, you can allow more gas
boiler operation by increasing [5‑01].
▪ Make sure to set the value of [5‑01] at least 1°C higher
than the value of [C‑03].
Boiler only ambient temperature
#
Code
[A.5.2.3]
[8-0E]
Boiler only ambient temp
When the ambient temperature is lower
than this temperature, the heat pump is
NOT allowed to work.
Range: –15°C~25°C
NOTICE
▪ If you install the bottom plate heater, you may lower the
operation range of the heat pump to Ta≥–15°C using
field setting [8-0E]=–15°C.
▪ If you do not install the bottom plate heater, keep
[8-0E]=–5°C.
For more information about the bottom plate heater, see
"5.2.2 Bottom plate heater" on
page 12.
System settings
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the remote controller settings at the time of the
power failure. Therefore, it is recommended to always enable the
function.

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.

Code
[A.6.4]

Outdoor average timer:
▪ 0: No averaging
▪ 1: 12 hours
▪ 2: 24 hours
▪ 3: 48 hours
▪ 4: 72 hours
Offset temperature external outdoor ambient sensor
Only applicable in case of an external outdoor ambient sensor is
installed and configured.
You can calibrate the external outdoor ambient temperature sensor.
It is possible to give an offset to the thermistor value. The setting can
be used to compensate for situations where the external outdoor
ambient sensor cannot be installed on the ideal installation location
(see installation).

Forced defrost
You can manually start a defrost operation.
The decision to execute the manual defrost operation is made by the
outdoor unit and depends on ambient and heat exchanger
conditions. When the outdoor unit accepted the forced defrost
operation,
will be displayed on the user interface. If
displayed within 6 minutes after forced defrost operation was
enabled, the outdoor unit ignored the forced defrost request.
