CT-DH-3P Atmospheric Controller 		CT-DH-3P Atmospheric Controller
Synchronized Outlets 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 equipment side to the exhaust side of the unit when either temperature, humidity or both are in excess of the dial settings. Plug the controller into 110V wall outlet. Set the temperature and humidity to the desired settings. The left or equipment side of the controller is normally in the "On" position and is able to activate CO2 equipment if needed. Equipment to be used for CO2 generation should be plugged into the left outlet. All equipment needed to exhaust the growing area should be plugged into the right outlet which is the exhaust side of the controller. The left outlet (CO2) is defeated whenever the exhaust outlet is activated. See optional thermostat sensors. Also available with built in photo sensor to defeat equipment (left) outlet during darkness periods. Indicate this option with a "P". (CT-DH-3P) Operates on 120VAC with 12 amp switching capacity.
