ABSTRACT:
A pressure control override apparatus for overriding a conventional pressure control starting switch on a refrigeration system is provided. The apparatus includes a power supply that receives power only when the valve in the liquid line of the refrigeration system is open. The apparatus also includes a temperature sensor for sensing the ambient temperature in the area of the compressor and condenser. The apparatus further includes a circuit to start the compressor that is separate from the normal pressure control starting switch when the apparatus is energized and the ambient temperature sensed by the temperature sensor is lower than a preselected temperature.
