Weather dependent operation
In space heating control, the leaving water temperature setpoint
mode can be:
▪ Fixed
▪ Weather dependent (the leaving water temperature is determined
automatically depending on the outdoor temperature)
You can change the setpoint mode for the:
▪ Main zone [2.4]
▪ Additional zone (if available) [3.4]
To modify the parameters for the weather-dependent curve ([2.5] for
the main zone and [3.5] for the additional zone, see below.
4.8.1
Detailed screen with weather-dependent
curve
When weather dependent operation is active the desired tank
temperature is determined automatically depending on the averaged
outdoor temperature. When the outdoor temperature is lower the
tank temperature will need to be higher as the water pipes will be
colder and vice versa.
The weather-dependent curves are defined by two setpoints:
▪ Setpoint (X1, Y2)
▪ Setpoint (X2, Y1)
Weather-dependent curve:
