Code
Description
N/A
[4-03]
Defines the operation permission of the
booster heater depending on ambient,
domestic hot water temperature or
operation mode of heat pump. This
setting is only applicable in reheat mode
for applications with separate domestic
hot water tank.
▪ 0: Booster heater operation is NOT
allowed
except
for
"Disinfection
function" and "Powerful domestic
water heating".
Only use this in case the capacity of
the heat pump can cover the heating
requirements of the house and
domestic hot water over the complete
heating season.
If the outdoor temperature is below
setting [5-03] and [5-02]=1, the
domestic hot water will not be heated.
The domestic hot water temperature
can be maximum the heat pump OFF
temperature.
▪ 1: Booster heater operation is allowed
when required.
▪ 2: The booster heater is allowed
outside the operation range of the heat
pump
for
domestic
hot
water
operation.
Booster heater operation is only
allowed if:
▪ Ambient temperature is out of the
operating
range:
T
a
<[5-03]
or
T
a
>35°C
▪ Domestic hot water temperature is
2°C lower than the heat pump OFF
temperature.

ON, the booster heater will be restricted
even when T
a
<[5-03]. See [C-02].
▪ 3 (default): The booster heater is
allowed when the heat pump is NOT
active in domestic hot water operation.
