3.16 Nominal d.h.w. temperature setpoint

• D.h.w. is heated only if there is demand for it.
• Possibility of using 2 different d.h.w. temperature setpoints
Setting range
TBWR...TBWmax
TBWR Reduced setpoint of the d.h.w. temperature (setting on operating line 770)
TBWmax Maximum nominal setpoint of the d.h.w. temperature (setting on operating line 750
The temperature setpoint during normal d.h.w. operation will be changed.

EXP
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 770): 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
operating lines 771, 773 and 774.
In the event of a sensor with an open-circuit, the d.h.w. will not be heated (risk of
scalding).
