CT-DH-4P Atmospheric Controller 		CT-DH-4P Atmospheric Controller
The CT-DH-4 and 4P is 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 offering independent outlets for temperature and humidity control. It is ideally suited for use with dehumidifiers. Temperature raise will activate the right hand outlets and deactivate the CO2 outlet. Humidity rise will activate the dehumidifying outlet. Internal sensors will allow a 7° temperature comfort zone and a 7% humidity (differential) between the time the equipment goes "Off "and comes back "On" again. Plug the controller into 110V wall outlet. 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. The photosensor will defeat CO2 enrichment during darkness hours. 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. This diagram shows how to install the CT-DH-4 for independent control of exhaust fans for cooling and a dehumidifier for removing unwanted humidity while synchronizing ventilation with CO2 enrichment. When the temperature raise above the predetermined setting, the CT-DH-4 initiates a venting cycle and CO2 generation is momentarily halted. 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 Cyclestat-4 timer has a built in photo sensor that prevents CO2 operation during darkness periods. If you are using a CO2 timer that does not have a photosensor you can get that option built into as a CT-DH-4P. The CO2 generator or emitter system are plugged into the Cyclestat and the Cyclestat is plugged into the CO2 outlet of the CT-DH-4. The dehumidifier is plugged into the left dehumidifying outlet. The exhaust fan is plugged into the right side.
