Description
The Schneider Electric (Barber Colman) TK-4012 is an electromechanical temperature controller intended primarily for HVAC equipment such as air conditioners and furnaces. It regulates the flow of heating or cooling fluids to keep the temperature within a specific range (30°F to 90°F). This gadget consists of a capillary bulb filled with a liquid that expands and contracts in response to temperature variations. These changes activate an internal switch that turns on or off the associated equipment, maintaining consistent comfort and energy efficiency. Simply said, the TK-4012 functions as a smart switch, automatically maintaining your set temperature by managing your HVAC system. This keeps you comfy and saves energy.
