▪ [1-00]: Low outdoor ambient
temperature. −40°C~+5°C (default:
−10°C)
▪ [1-01]: High outdoor ambient
temperature. 10°C~25°C (default:
15°C)
▪ [1-02]: Desired leaving water
temperature when the outdoor
temperature equals or drops below
the low ambient temperature.
[9‑01]°C~[9‑00]°C (default: 35°C).
Note: This value should be higher
than [1-03] as for low outdoor
temperatures warmer water is
required.
▪ [1-03]: Desired leaving water
temperature when the outdoor
temperature equals or rises above
the high ambient temperature.
[9‑01]°C~min(45, [9‑00])°C (default:
25°C).
Note: This value should be lower
than [1-02] as for high outdoor
temperatures less warm water is
required.

▪ [1-06]: Low outdoor ambient
temperature. 10°C~25°C (default:

▪ [1-07]: High outdoor ambient
temperature. 25°C~43°C (default:

▪ [1-08]: Desired leaving water
temperature when the outdoor
temperature equals or drops below
the low ambient 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.
[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.
Leaving water temperature: Additional zone
Only applicable if 2 leaving water temperature zones are present.
# Code Description
[A.3.1.2.1] N/A LWT setpoint mode:
▪ Fixed (default): The desired leaving
water temperature is:
▪ NOT weather-dependent (i.e. does
NOT depend on the outdoor
ambient temperature)
▪ fixed in time (i.e., NOT scheduled)
▪ Weather dep.: The desired leaving
water temperature is:
▪ weather-dependent (i.e. depends
on the outdoor ambient
temperature)
▪ fixed in time (i.e., NOT scheduled)
▪ Fixed/scheduled: The desired leaving
water temperature is:
▪ NOT weather-dependent (i.e.,
does NOT depend on the outdoor
ambient temperature)
▪ according a schedule. The
scheduled actions are On or OFF.
Remark: This value can only be
set in leaving water temperature
control.
▪ WD/scheduled: The desired leaving
water temperature is:
▪ weather-dependent (i.e., does
depend on the outdoor ambient
temperature)
▪ according a schedule. The
scheduled actions are On or OFF.
Remark: This value can only be
set in leaving water temperature
control.
