A temperature control system used in association with a heating and cooling system supplying warm or cool air to a duct system for maintaining accurate temperature in a zone of multiple zones utilizing a microcomputer based thermostat for modulating a damper assembly in the duct system feeding the zone, thereby controlling the volume of air flow in the duct system to the zone to match the load in each zone. The thermostat has a digital readout display thereon indicating the temperature to be maintained in the zone and which can selectively display the duct temperature of air and/or the zone temperature of the air. The thermostat controls a damper assembly which includes a stepper motor for pivoting the damper blade between open and closed positions with the duct temperature sensor located before the damper blade in the duct. Calibration to provide setting of the zone temperature to conform with an accurate thermometer is provided in the thermostat, as well as selectable stop positions for the damper blade.
