2.41 Boost of flow temperature setpoint for
d.h.w. heating (UEBW)
Efficient d.h.w. heating.
To allow the d.h.w. to be heated up, the boiler temperature must be higher than the
d.h.w. setpoint.
Setting range
0...30
The setting will raise the boiler temperature setpoint when there is demand for d.h.w.
Increase: Heating up time will become shorter
More overshoot
Decrease: Heating up time will become longer
Less overshoot
Using the two settings, the controller generates the boiler temperature setpoint for
d.h.w. heating.

For d.h.w. control, refer to "switching differential of d.h.w." in index.
