5.36.2 D.h.w. temperature control with 2 sensors
The d.h.w. temperature is acquired with 2 temperature sensors connected to terminals
B3 and B31.
The control considers the actual values of the sensor for the higher and the lower
temperature as follows:
D.h.w. ON: TBWx of both sensors = TBWw – SDBW
D.h.w. OFF: TBWx of both sensors = TBWw
If the d.h.w. temperature is controlled with 2 sensors, the respective setting must be
made on line 174.
