10.4.3 Slope-offset curve
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.
