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:
