4.8 Weather dependent operation
In space heating/cooling control, the leaving water temperature setpoint mode can
be:
▪
Fixed
▪
Weather-dependent (the leaving water temperature is determined automatically
depending on the outdoor temperature)
To select the setpoint mode, see the installer reference guide.
To set the parameters for the weather-dependent curve, see below.

Desired leaving water temperature when the outdoor temperature equals or drops
below the low ambient temperature.
Note:
in heating, this value should be higher
than (d) as for low outdoor temperatures warmer water is required. In cooling, this
value should be higher than (d) as for low outdoor temperatures less cold water
suffices
d
Desired leaving water temperature when the outdoor temperature equals or rises
above the high ambient temperature.
Note:
in heating, this value should be lower
than (c) as for high outdoor temperatures less warm water is required. In cooling,
this value should be lower than (c) as for high outdoor temperatures colder water is
required.
