Green Air CT-DH-3P Cooling thermostat & Dehumidistat
Green Air Synchronized Cooling Thermostat & Dehumidistat Model CT-DH-3P
With Light Activated Photosensor 4 Outlets
CT-DH-3P (Photo Sensor Option)
| The CT-DH-3P is installed for cooling and dehumidifying control. This unit may be used independently or with many other Green Air Products controls to create an integrated system. When the temperature or humidity raise above the predetermined setting, the CT-DH-3P initiates a venting cycle and CO2 generation is momentarily halted. The Cyclestat is used to time the frequency and duration of the CO2 production. In the event of an exhaust cycle the Cyclestat will reset and immediately replenish CO2 enrichment upon completion of the exhaust function. The CT-DH-3P has a built in photo sensor that prevents CO2 operation during darkness periods. |
|
The CO2 generator or emitter system are plugged into the Cyclestat and the Cyclestat is plugged into the left outlets of the CT-DH-3P. The fan is plugged into the right side.
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 7ºF 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 7º and/or the humidity drops 5% below your set points. At which time, the right outlets will shut “OFF” and reactivate the left outlets.
PHOTOSENSOR
The CT-DH-3p has a built in photosensor 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.
|
| 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. |
 |
Installation Example
 |
The CT-DH-3 operates on 120 Volt AC with 15 Amp 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. |
