Setting The Functional Parameters - Riello ALU PRO power Series Instructions For The Installer And The Technical Assistance Centre

If an outdoor temperature sensor is connected, the controller uses the heating curve to generate the CH flow tempera-
ture setpoint, thus enabling the boiler to maintain a constant room temperature even without the use of an ambient unit
.The steeper the slope of the heating curve, the higher the flow temperature setpoint at low outdoor temperatures (see
"Installer" parameter 532).
