This patent describes a temperature control system for maintaining the temperature of a zone at a predetermined set point by controlling air flow into the zone comprising a damper assembly remote from the zone and oriented partially in a duct supplying conditioned air to the zone for controlling the air flow into the zone, and a thermostat located in the zone to be controlled. The thermostat includes movable means adjusted to the predetermined set point to be maintained in the zone and operatively connected to the remote damper assembly. The damper assembly includes a damper blade means movable between open and closed positions in the duct and further include a motor assembly remote from the zone and the duct for driving the damper blade means selectively in either direction between open and closed positions, the motor assembly including an electrical stepper motor. The damper assembly includes an actuating arm connected to the damper blade means, and means drivingly connecting the motor to the actuating arm to move the damper blade means in response to actuation of the motor in either direction between open and closed positions. The thermostat includes logic means for providing a series of logic pulses to the stepper motor for controlling the operation of the stepper motor and varying the position of the damper blade means to reduce or increase the volume of air flowing through the duct into the zone to be controlled.
