Abstract
A compressor discharge pressure control for a unitary outdoor fan, multi-split air conditioning system having multiple compressors, multiple evaporator coils, multiple condenser coils and a single outdoor fan. Pressure comparison circuitry compares the discharge pressures of the compressors to predetermined pressure levels to generate a plurality of pressure state signals. On/off monitoring circuitry monitors the on/off states of the compressors to generate a plurality of compressor state signals. Control circuitry controls the fan in accordance with both sets of signals under a predetermined priority scheme.
