Abstract: An HVAC system for controlling the temperature and humidity of air supplied to a comfort zone includes a heater and a cooler operating concurrently. In response to a supply air temperature sensor, a PID control loop with substantially constant gain controls the cooler to maintain the zone air at a certain comfortable temperature. The heater, also under PID control, is controlled in response to a humidistat.

When the cooler is operating above the predetermined limit, the multiplier varies linearly between positive-one and negative-one and does so inverse-proportionally with the cooling load to smoothly change the heater's PID control from direct acting to reverse acting as the cooler approaches its maximum capacity.
