While the CT-DH-3 has many applications, it was primarily developed to be used with CO2 equipment and exhaust type fans. Internal sensors will allow a 7 temperature comfort zone and a 7% humidity (differential) between the time the fans go Off and come back On again. Temperature or humidity raise will activate the right hand outlets and deactivate the left hand outlets. The CT-DH-3 has an internal relay that automatically switches power from the left side (CO2 Outlets) to the right side (Exhaust Outlets) of the unit when either temperature, humidity or both are in excess of the dial settings. Plug the controller into a power surge protector to protect your valuable equipment, and then plug the surge protector into a 110 wall outlet. Set the temperature and humidity to the desired settings. The left side of the controller is normally in the ON position and is able to activate CO2 equipment as needed.
