Abstract
A control system for a compressor is provided. The control system includes a controller and first and second control portions. The first control portion is configured to assess an actual temperature of an evaporator and a target temperature of the evaporator and to generate a first compressor speed command signal. The second control portion includes a pressure calibration value and is configured to receive a pressure reading of the climate system, to compare the pressure reading to the pressure calibration value and to generate a second compressor speed command signal. The controller device includes data and is configured to receive the first compressor speed command signal and the second compressor speed command signal and to transmit a control signal to the compressor for causing the compressor to operate at a commanded compressor speed based on the first compressor speed command signal, the second compressor speed command signal, and the data.
