Green Air Products Independent Cooling & Heating Thermostat w/4 Outlets - Model CT-HT-2
This controller 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 a tighter control of your temperature than the internal heating\cooling thermostats allow, alternate sensors are available with a 3º differential External Coil or Remote Bulb Thermostat.
