Johnson Controls A72AA-1 DPST Electro Mechanical Temperature Control 3030°F 6 425F Diflow

The Johnson Controls A72AA-1 DPST Electro Mechanical Temperature Control is a switch designed to regulate temperature within a specific range in HVAC systems. It works by using a bimetallic strip that reacts to changes in temperature. As the surrounding temperature rises, the strip bends, triggering the switch to open or close an electrical circuit. This, in turn, controls the operation of HVAC equipment like heating elements or cooling compressors. The A72AA-1 offers a temperature range of -30°F to 30°F, with an adjustable differential between 4°F and 25°F. This allows for precise control over temperature fluctuations. It can handle up to 24 amps and is compatible with 120/208/240 volt AC power supplies. The DPST (Double Pole Single Throw) design ensures a clean and reliable switching operation. the A72AA-1 is its simplicity. It's an electro-mechanical device, meaning it doesn't require complex programming or external controllers. This makes it a cost-effective solution for maintaining consistent temperatures in various HVAC applications.
