0-10V DC remote flow temperature set point
The hot water temperature is controlled by connecting an external 0-10V DC signal to the water heater (connections 15-16).
P5BB Analogue input Config (0=off 1=temp) (display D1).
This parameter must be set at "1" so the supplied 0-10 V dc signal will control the temperature set point.
Possible settings are:
0 = 0-10V control off
1 = 0-10V temperature set point control active
See also the following graph for the relation between the temperature and the control signal.
