5.5 AHS provides heat for space heating and DHW
Space heating application by either the unit or by AHS connected in the system. Bivalent operation is possible for both
space heating operation and domestic water heating operation. If AHS is also providing heat for domestic hot water, AHS
can be integrated in the piping work. In this condition, the unit can sent ON/OFF signal to AHS in heating mode, but AHS
control itself in DHW mode.
