Abstract
The disclosed apparatus includes separate 'heat' and 'cool' registers and selective switching means that connects the output of a thermal energy computer to one register or the other in accordance with use of a room heat-exchanger to produce heating or cooling. The switching means also interchanges the connections of inlet and outlet fluid temperature sensors in the computer corresponding to heating or cooling operation of the system. The temperature sensors control the switching means for automatic selective operation. The flow meter is in the outlet of the room heat-exchanger, to undergo a minimized range of temperatures under all conditions, and the computer provides correction for temperature-induced error of the flow meter.
