CT-DH-3(P) Cooling and Dehumidifying Controls - Synchronized Outlets

While the CT-DH-3 has many applications, it was primarily developed for use with CO₂ equipment and exhaust/ventilation fans. The left side (or equipment) outlets of the controller are normally "on" until defeated when the right side outlets are activated. Internal sensors will allow for 7°F temperature zone and a 5% humidity differential between the time that the fans come "on" and then turn "off" again. When temperature or humidity rises above your dial set points, the right outlets will activate and the left outlets will deactivate. The right side outlets will remain "on" until the temperature drops 7° and/or the humidity drops 5% below your set points. At which time, the right outlets will shut "off" and reactivate the left outlets.

Exhaust or ventilation fans, cooling or dehumidifying equipment should be plugged into right side outlets. CO₂ enrichment systems or other equipment you want to defeat during exhaust cycles, should be plugged into left side outlets.

The CT-DH-3 operates on 120V AC with 15A maximum switching capacity and is intended for indoor use only. Be sure to locate your atmospheric controller where it will accurately sample and respond to the average air conditions. Good air circulation around the controller and in your garden space is essential. Avoid locating the controller in a draft or in direct sunlight.

Optional Photosensor

The CT-DH-3 is also available with a built in photo sensor (CT-DH-3P) to defeat the left outlets during periods of darkness. This optional feature is especially useful when using the controller in conjunction with CO₂ enrichment systems.
