The heating setpoint is calculated based on the outside temperature via the outdoor air temperature sensor.
To select the curve, the two below parameters as well as parameter 740 & 741 must be set:
-
Parameter 720: Heating Curve Slope
Each slope value identifies one of the different curves shown in the above diagram.
-
Parameter 721: Shifting Heating Curve
Each curve can be shifted vertically (higher or lower) to modify the setpoint.
For example:

Analogue Input 0-10v
This setup is designed for an analogue input 0-10v control system to be connected to terminals M & H1(+) which will
activate the heat pump and define the heating setpoint.
The analogue input defines the setpoint on the return
temperature (water inlet to the unit).
The setpoint is calculated as a function of the value of this
analogue input by the linear interpolation between 2
setpoint values (for 0 and 10v) defined by the user.
