Green Air Products has designed
a complete line of atmospheric controllers. We are certain one of them is right for you.
They are designed to monitor temperature and humidity and operate fans, air conditioning,
humidifiers, dehumidifiers and misting systems etc.. Our controls are mounted in brush
finish anodized aluminum housings which provide superior resistance to corrosive humid
atmospheres for years of dependable service. Illuminated switches and function indicator
lights mounted in a black housing with an easy to read white dial face make our equipment
an attractive addition to your system. Green Air Products atmospheric controllers are
designed to easily plug into wall outlets or each other for easy installation. All
controllers are fully assembled and ready to use and no hard wiring is required. Green Air
Products uses only high quality UL listed components chosen to meet the specialized
needs of a greenhouse or grow room climate. Most of our controllers are dual function and
designed to work alone as an independent control or connect to other controls to
simultaneously coordinate other functions. Thermostats are available in several styles and
ranges. Generally controllers operate on 110 volts, however, units that operate at 240
volts may be specified by adding 240V to the model number (i.e. CT-DH-1-240V). High
capacity relays (up to 30 amps) are also available upon request for either configuration.
When ordering equipment to be installed in countries other than the U.S. please be sure to
note this so the equipment may be properly wired for that country. Review the following
pages for specific information on the equipment that you need. The following examples
define only some of the operations and combination possible for synchronized control. Any
of our many controllers can be interconnected with any others with no fear of equipment
damage or malfunction. There is no wrong way only different ways. Feel free to experiment.

The following
descriptions will explain the features of the various models available. This will help you
choose the controller most suited to your needs. The CT-DH-3P is the most popular model
for operating your intake and exhaust fans based upon temperature and humidity, while
coordinating ventilation with CO2 enrichment.

EXAMPLE:
CT-DH-3P
Cooling Thermostat (CT)
Dehumidifying Humidistat (DH)
Synchronized Outlets (3)
Photo Sensor (P)
Integrated Outlets:
The left outlet is an alternate power outlet for the thermostat
Independent Outlets:
The right and left outlets work independently ( i.e. humid for left - temp for
right)
Synchronized Outlets:
The right outlet works alternately (defeats) the left outlet
Split Duplex Outlet:
The individual duplex receptacles are split and to control various synchronized
or independent functions.

Optional Thermostat Sensors
|
*External Coil (Optional sensor type "X")
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 |
*Remote Bulb (Optional sensor type "R")
This unit has all of the great features of the external
sensor with the added advantage of a flexible bulb extension. This lends itself applicable
to soil or nutrient heating or cooling systems. Suitable for propagation heating mats or
hot water heating circuits. Allows controller to be mounted outside greenhouse or growth
chamber with sensor inside. Extra long 10ft. flexible sensor lead provides versatile
applications. Four degree differential between on / off functions.
* Refer to this option by adding an "R" after the model number. Example : CT-DH-3R |
