The present invention relates to a self-contained air conditioning unit including a reversible refrigeration system and more particularly to a control system having a plurality of sensing means that are effective in maintaining operation of the unit in a heat pump mode when the ambient and the surface temperature of selected refrigeration components are above a preselected frosting temperature, and to energize a heating means to provide uninterrupted heating when the ambient and surface temperatures sensed are below a preselected frosting level which terminates compressor operation.
