The Ranco A12-701 A12 Constant Cut-In Temperature Control A12 is a mechanical control unit that is used to keep a pre-set minimum temperature in equipment that is compatible with it. It reacts to the temperature sensed by its temperature probe, and switches the circuit at a fixed cut-in point to enable it to perform heating or cooling work as needed. This control is attached to the equipment housing. It is a component of the temperature control system that assists in controlling the operation cycles through constant cut-in operation.
