WATER OUTLET SET POINT COMPENSATION BASED ON OUTSIDE AIR TEMPERATURE, HEATING CURVE (SLOPE).
Parameter
number
Description
The heating curve compares the outside temperature and the water outlet temperature fort heating.
The slope can be modified to allow correct operation of the heat pump based on the type of heating circuit
(radiant panels, radiators etc.).
Example: Selecting heating curve 1.5, with an outside air temperature of -5°C, gives a water outlet tempera-
ture of +55°C.
To display the calculated outlet temperature set point, press the info
button, then turn the knob until dis-
playing “outlet set point 1”.
Select the desired slope of the heating curve using parameter 720.
A heating curve that is too high means an excessive outlet temperature, a curve that is too low may mean the
desired room temperature is not reached.
Default setting
720 = 1,5

OUTLET TEMPERATURE SET POINT LIMIT
Parameter
number
Description
Parameters 740 and 741 define the temperature limits (minimum and maximum) for the circuit that will never
be exceeded, as shown in the following graph:
TVw Outlet temperature set point
740 = Tvmin Minimum outlet temperature set point
741 = TVmax Maximum outlet temperature set point
Default setting
740= 10°C
741= 60°C
