Johnson Controls A421GEF-01C Temperature Control NEMA 4X 24 VAC

The Johnson Controls A421GEF-01C Temperature Control NEMA is an ideal device that is used in HVAC systems in order to control the temperature. It has a temperature control between 40°F and 212°F and works at 24V with the SPDT connection type for managing heating or cooling. This control signal works in two positions to make sure that temperature is well regulated. Mainly applied in commercial and industrial air conditioning systems, this control unit provides stable output for the temperature control within a certain range. Its fail safe mode which has a spring return mechanism with a closed position is safer than the other types since it has a default setting in case of power failure or system malfunction.
