INFORMATION
Maximum and minimum setpoints
You cannot configure the curve with temperatures that are higher or lower than the
set maximum and minimum setpoints for that zone or for the tank. When the
maximum or minimum setpoint is reached, the curve flattens out.
To fine-tune the weather-dependent curve
The following table describes how to fine-tune the weather-dependent curve of a
zone or tank:

Preset leaving water temperature
You can define preset leaving water temperatures:
▪ economic (denotes the desired leaving water temperature which results in the
lowest energy consumption)
▪ comfort (denotes the desired leaving water temperature which results in the
highest energy consumption).
Preset values make it easy to use the same value in the schedule or to adjust the
desired leaving water temperature according to the room temperature (see
modulation). If you later want to change the value, you ONLY have to do it in one
place. Depending on whether the desired leaving water temperature is weather
dependent or NOT, the desired shift values or the absolute desired leaving water
temperature should be specified.
NOTICE
The preset leaving water temperatures are ONLY applicable for the main zone, as the
schedule for the additional zone consists of On/OFF actions.
