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 ”œOff”œ and come back ”œOn” again. Temperature or humidity rise will activate the right hand (Exhaust Outlets) outlets and deactivate the left hand outlets (CO2 Outlets). 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.
