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.
4.8.1 To set the weather dependent settings
Prerequisite: You switched the permission level to Advanced end

Outdoor temperature
a Low outdoor ambient temperature
b High outdoor ambient temperature
c 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.
