D.h.w. heating
640 Heat source strategy for d.h.w. heating:
1
D.h.w. according to the current heat source sequence
2
D.h.w. with lag heat source, lead heat source controls to space
heating setpoint during d.h.w. heating
3
D.h.w. with lag heat source, lead heat source during d.h.w.
heating OFF
4
D.h.w. with lag heat source if released, lead heat source controls
d.h.w. heating to space heating setpoint
5
D.h.w. heating with lag heat source if released, lead heat source
during d.h.w. heating OFF
