# Code Description
[7.7.1.2] [1‑06]
[1‑07]
[1‑08]
[1‑09]
<< continuation
▪ [1‑06]: Low outdoor ambient temperature.
10°C~25°C (default: 20°C)
▪ [1‑07]: High outdoor ambient temperature.
25°C~43°C (default: 35°C)
▪ [1‑08]: Desired leaving water temperature
when the outdoor temperature equals or
drops below the low ambient temperature.
Between minimum and maximum leaving
water temperature [9‑03]°C~[9‑02]°C
(default: 22°C).
Note: This value should be higher than [1-09]
as for low outdoor temperatures less cold
water suffices.
▪ [1‑09]: Desired leaving water temperature
when the outdoor temperature equals or
rises above the high ambient temperature.
Between minimum and maximum leaving
water temperature [9‑03]°C~[9‑02]°C
(default: 18°C).
Note: This value should be lower than [1-08]
as for high outdoor temperatures colder
water is required.
INFORMATION
In order to optimise comfort as well as running costs, it is recommended to choose
weather-dependent setpoint operation. Set the settings carefully; they have
significant influence on heat pump as well as boiler operation. Too high leaving water
temperature can result in constant boiler operation.
Leaving water temperature: Additional zone
Only applicable if 2 leaving water temperature zones are present.
# Code Description

depend on the outdoor ambient
temperature)
- fixed in time (i.e., NOT scheduled)
▪ Weather dep. (default): The desired leaving
water temperature is:
- weather-dependent (i.e. depends on the
outdoor ambient temperature)
- fixed in time (i.e., NOT scheduled)
