REMOTE FLOW TEMPERATURE SET POINT
The hot water temperature is controlled by connecting an external 0-10 VDC signal to the water heater (connec-
tions 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.
The graph is only for illustration purposes, parameter values in the water heater can deviate.
