Three different possible water temperature set-point configuration modes for each zone
• OTC Points: Water target is selected by an Outside Temperature Compensated (OTC) control that is defined by 4
different points (Minimum and maximum water outlet temperature vs Minimum and maximum outdoor ambient tempe-
rature).

OTC Gradient (Only for heating space): Water target is selected by an Outside Temperature Compensated (OTC)
control that is defined by a different gradient of the curve. The initial point of the curve is always 20ºC-20ºC (Water
outlet target 20ºC at outdoor ambient temperature of 20ºC).
