Abstract

A system for controlling the operation of an air distribution fan and the operation of a motorized outside air damper of an air conditioning system, having heating and/or cooling and/or humidifying and/or dehumidifying operating modes. The system includes a fan recycling control for periodically energizing and de-energizing an air distribution fan in an air conditioning system in order to operate the air distribution fan for a first selectable time period after a second selectable time period from the end of the last operation of the air distribution fan. The last operation of the air distribution fan could have been due to the heating or cooling or humidifying or dehumidifying or constant fan modes of the air conditioning system, or due to fan operation initiated by the fan recycling control. The system includes an outside air damper recycling control that can open a motorized outside air damper, for the purpose of drawing in ventilation air, each time the air distribution fan operate
