8.2.5 Space heating/cooling control
The basic required settings in order to configure the space
heating/cooling 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.

Q
[1-00]: Low outdoor ambient
temperature. –20°C~5°C (default:
–10°C)
Q

Q
[1-02]: Desired leaving water
temperature when the outdoor
temperature equals or drops below
the low ambient temperature.
Between minimum and maximum
leaving water temperature (default:
40°C).
Note: This value should be higher
than [1-03] as for low outdoor
temperatures warmer water is
required.
Q
[1-03]: Desired leaving water
temperature when the outdoor
temperature equals or rises above
the high ambient temperature.
Between minimum and maximum
leaving water temperature (default:
25°C).
Note: This value should be lower
than [1-02] as for high outdoor
temperatures less warm water is
required.
