CT-DH-3P
The CT-DH-3 was primarily developed to be used with exhaust fans and CO2 equipment. The internal sensors allow a 7° temperature comfort zone and a 7% humidity differential between the time the fans go "Off "and come back "On" again.

When the fans come on, the CO2 equipment outlet is turned off. The built in photo sensor defeats equipment CO2 equipment outlet during darkness periods. These features ensure that you are not wasting CO2.

The CD-DH-3p is very easy to use. Plug the controller into a 110V wall outlet. Set the temperature and humidity to the desired settings. The left or equipment side of the controller is normally in the "On" position and is able to activate CO2 equipment if needed.

Equipment to be used for CO2 generation should be plugged into the left outlet. All equipment needed to exhaust the growing area should be plugged into the right outlet which is the exhaust side of the controller.

The left outlet (CO2) is defeated whenever the exhaust outlet is activated.

The CT-DH-3p is designed for 15 amp output. Do not exceed a total power draw of over 15 amps directly thru the unit.
