5.4.3 Auxiliary heat source provides addional heang
If the units outlet temperature is too low, the auxiliary heat source provides addional heang to raise the water temperature
to the set temperature. An addional 3-way valve is required. When the units outlet temperature is too low, the 3-way valve is
open and the water ows through the auxiliary heat source. When the unit’s outlet temperature is high enough, the 3-way valve
is closed.
