Green Air CT-HT-2 (formerly CT-HT-1) Cooling and Heating

More products from:   Green Air

The Green Air CT-HT-2 controller features fully independent sensors for cooling and heating equipment. The cooling thermostat activates the left outlet of the controller and the heating thermostat activates the right outlet. 

If you require a tighter control of your temperature than the internal heating \ cooling thermostats allow, alternate sensors are available with a 4° differential. Operates on 110VAC with 15 Amp switching capacity.

Plug cooling equipment into left side outlets. Plug heating equipment into right side outlets. Standard thermostats are accurate to ± 7°.

If your growing situation requires the temperature to be no cooler than 50° and no hotter than 70° you would set your heating thermostat to 57° and the cooling thermostat for 63° to allow for the thermostat differential.

This would give you a minimum buffer zone of 6° and a maximum of 20°. Do not exceed power handling capacity of your wall outlet.
