The WTDC Wireless Thermostat Damper Control eliminates overheating or overcooling in a space, and reduces the wasted energy heating and cooling unoccupied spaces. The WTDC uses the Set To temperature set by the user and the space temperature to automatically control a modulating damper to adjust the amount of heating or cooling airflow to the space for optimum comfort and energy savings. 
Automatic control of airflow to the space.
