CT-DH-4XP Atmospheric Controller w/ External Coil 		CT-DH-4XP Atmospheric Controller w/ External Coil
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. This feature is available on all of our thermostat apparatus. This sensor coil operates on the expansion of fluids much like a mercury thermometer and is very sensitive to subtle changes. With the sensor mounted externally it has better reference to room temperature. Extra stable performance especially in high load applications. Four degree differential between on/off functions. The best sensor choice for greenhouse installations where intense sunlight can create radiant heat. * Refer to this option by adding an "X" after the model number. Example : CT-DH-3X
