Setting "Maximum nominal setpoint of d.h.w. temperature”
D.h.w. heating has 2 different setpoints that can be used:
Nominal setpoint of d.h.w. temperature: It ensures the d.h.w. temperature required
during main occupancy times
Reduced setpoint of d.h.w. temperature (setting on line 120): It ensures the d.h.w.
temperature required outside main occupancy times
The times at which these d.h.w. setpoints shall apply can be set with the d.h.w.
program on line 121.
