COOLING and HEATING CONTROL

 

CT-HT-2

Independent Outlets

 

This 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 controller power cord into 110V outlet. Plug cooling equipment into left side outlets. Plug heating equipment into right side outlets. Standard thermostats are accurate to 7. If your 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 . Do not exceed power handling capacity of your wall outlet.

Installation Example

Independent control of heating and cooling equipment. High amperage relays ( HAR-1 ) are available for large draw fans and heaters. Transformers available for low voltage gas fired heaters.
When the temperature falls below the predetermined setting the heating units are activated and CO2 enrichment will be unaffected. The left clock on the 24 Hour Dual Timer is set to "On" for the hours in which CO2 enrichment is desired. The right clock may be used for lighting or other independently timed equipment. The IR-1 is used to monitor output from CT-HT-2 and the 24 Hour Dual Timer. Current is switched between the left and right outlets depending on timer position and atmospheric condition. When the CT-HT-2 determines that venting is necessary, carbon dioxide generation is momentarily halted. If the 24 Hour Dual Timer is in the "Off" position CO2 generation is defeated, but the venting process will continue as needed. The CST-1 is used to time the frequency and duration of the CO2 emissions.
