ABSTRACT:
The heating and cooling system for a multiple coil installation includes a bypass passage or conduit provided with a check valve which is closed when the pump of either the heating circuit or the cooling circuit is energized and which is opened when the pumps of the heating circuit and the cooling circuit are not energized whereby a third pump which operates continuously, is effective when the check valve is open to continuously circulate the water in a closed path through the bypass circuit which is interconnected to the inlet and outlet sides of the multiple coil installation, thus bypassing the heating and cooling circuits.
