The THC-2 can be switched between humidify and dehumidify for removing unwanted atmospheric moisture accumulating within an enclosed area or to add needed moisture to the air by means of humidification. The THC-2 humidity switch controls humidity equipment by providing power when humidity varies from the adjustable set point. In the dehumidifying mode high humidity conditions will activate fans or other dehumidifying apparatus until level drops approximately 5% in relative humidity. At this point dehumidifying equipment is disabled until humidity increases again 5%. In the humidifying mode this control operates fogging or other humidifying equipment by activating switches, motors, valves or pumps. Humidifiers can be precisely controlled according to atmospheric humidity to create ideal conditions for any environment. The 110V outlet receptacle receives power when atmospheric moisture content becomes less then your preset minimum allowable percentage. Switches 120 V at 15 amp maximum. Sensor allows a 5% (differential) comfort zone between "on" and "off" functions. If your humidifier or dehumidifier already has a humidity control, turn it to full on position and set the humidity dial to your minimum desired level. The THC-2 can also be used with many other types of humidity equipment or any other electrically triggered appliances.
