PERATE
Plug controller power cord into a surge protector and then plug the
surge protector into a 110V wall outlet. Plug cooling equipment into left
side outlets. Plug heating equipment into right side outlets. This
controller offers a 7° differential. That means, 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 50° and the cooling
thermostat for 70°. Then, if the temperature drops to 50°, the controller
will activate your heating equipment until the temperature reaches 57°.
Conversely, if the temperature reaches 70° the controller will activate
cooling equipment until the temperature drops to 63°. Do not exceed
power handling capacity of your wall outlet or the controller.

The CT-HT-2 features fully independent sensors for cooling and heating
equipment. The cooling thermostat activates the left outlets of the
controller and the heating thermostat activates the right outlets. If you
require tighter temperature control than the internal thermostats allow,
external coil and remote bulb thermostats with a 3° differential are
available. Operates on 115VAC with 15 Amp switching capacity.
Approved for indoor use only.
