This CT-DH-1 is designed to turn “On” and “Off” exhaust fans and/or intake fans to remove unwanted atmosphere due to heat or humidity. This device is intended as a cooling and dehumidifying control. This controller is ideal for situations where excess heat and humidity need to be exhausted. Internal sensors will allow a 7° temperature comfort zone and a 7% humidity span (differential) between the time the fans go “Off” and come back “On” again. When either temperature or humidity exceeds the dial settings, all four outlets will turn “ON”, activating any cooling or exhaust equipment plugged into the controller.
