8.2.5 Space heating control
The basic required settings in order to configure the space heating of
your system are described in this chapter. The weather-dependent
installer settings define the parameters for the weather-dependent
operation of the unit. When weather-dependent operation is active,
the water temperature is determined automatically depending on the
outdoor temperature. Low outdoor temperatures will result in warmer
water and vice versa. During weather-dependent operation, the user
has the possibility to shift up or down the target water temperature
by a maximum of 5°C.
See the user reference guide and/or operation manual for more
details about this function.

▪ 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 consists of
desired shift actions, either preset
or custom.
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 consists of
desired
leaving water
temperatures either preset or
custom.
Remark: This value can only be

▪ [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.
Leaving water temperature: Additional zone
Only applicable if 2 leaving water temperature zones are present.
