CT-DH-4 Cyclestat -- Cooling and Dehumidifying Controls - Independent Outlets with CO₂

The CT-DH-4 and CT-DH-4P are designed to be used with CO₂ equipment, dehumidifiers, and exhaust fans. While it is similar to the CT-DH-3 it has the added feature of independent outlets for temperature and humidity control. It is ideally suited for use with dehumidifiers. Temperature above your set point will activate the right hand outlets and deactivate the bottom left "CO₂" outlet. Humidity will activate the top left "Dehumidify" outlet. Internal sensors will allow a 7°F temperature comfort zone and a 5% humidity (differential) between the time the equipment comes "on" and goes back "off" again. Set the temperature and humidity to the desired settings. The CO₂ outlet is normally in the "on" position and is able to activate CO₂ equipment as needed. An optional photo sensor will defeat CO₂ enrichment during darkness hours. Intended for indoor use only. The CT-DH-4 operates on 120Vs AC with 15A max switching capacity.

The CT-DH-4 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 exceeds the dial set points, the CT-DH-4 initiates a venting cycle and CO₂ generation is temporarily defeated. The Cyclestat-4 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 CO₂ generator or emitter system is plugged into the Cyclestat and the Cyclestat is plugged into the bottom left CO₂ outlet of the CT-DH-4. The dehumidifier is plugged into the top left "dehumidify" outlet. The exhaust fans are plugged into the right outlets.

Optional Photosensor

The Cyclestat-4P timer has a built in photo sensor that prevents CO₂ operation during darkness periods.
