Detailed screen with weather-dependent
curve
When weather-dependent (WD) operation is active the desired
leaving water or tank temperature is determined automatically
depending on the averaged outdoor temperature. When the outdoor
temperature is lower the leaving water or tank temperature will need
to be higher as the water pipes will be colder and vice versa.
Slope and offset
Define the weather-dependent curve by its slope and offset:
▪ Change the
slope
to differently increase or decrease the
temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is in
general fine but at low ambient temperatures too cold, raise the
slope so that leaving water temperature is heated increasingly
more at decreasingly lower ambient temperatures.
▪ Change the
offset
to equally increase or decrease the
temperature of the leaving water for different ambient
temperatures. For example, if leaving water temperature is always
a bit too cold at different ambient temperatures, shift the offset up
to equally increase the leaving water temperature for all ambient
temperatures.
