D.h.w. values
3.11 Nominal d.h.w. temperature setpoint
• D.h.w. heating only if there is a demand for it
• Possibility of using 2 different d.h.w. temperature setpoints
1. Press the operating line selection buttons to select line 13.
2. Press the + / – buttons to adjust the nominal setpoint of the d.h.w. temperature.
Setting range Unit Factory setting

Setting "Maximum nominal setpoint of the d.h.w. temperature”
D.h.w. heating has 2 different setpoints that can be used:
• Nominal d.h.w. temperature setpoint: It ensures the d.h.w. temperature required
during main occupancy times
• Reduced d.h.w. temperature setpoint (setting on operating line 120): it ensures the
d.h.w. temperature required during the main occupancy times.
The criteria required for releasing d.h.w. heating are defined by the settings made on
lines 121 and 123 and 124.
In the event of a sensor with a short-circuit (display ”- - -” in input test, test step 1) the
d.h.w. will not be heated (protection against scalding).
