3.5.2 Setpoint
Depending on the unit configuration, the system control can be
based on the water or air setpoint control.
To achieve greater comfort, you can adjust the room temperature
setpoint (remote user interface) or the water temperature setpoint
(local user interface) according to your needs. Please note that the
temperature value can only be adjusted within the range defined
for each occupation mode.

The calculation of the water setpoint can be based on:
Predefined climatic curves
based on the OAT: climatic curves
already defined in the control logic.
Fixed water setpoint:
by entering a fixed value for each occupa

tion mode.
Custom climatic curve
based on the OAT: defines climatic curves
customized according to the application.
Offset on climatic curves (predefined and user-defined)
Default climatic curves

postata su "0", "1" o "2", the water set point will be calculated based
on the selected cooling climatic curve.
