Abstract
An apparatus and method for controlling continuously and discretely the speed of an indoor evaporator fan motor and the speed of the compressor as a function of the fan speed for regulating the dry bulb temperature and relative humidity of a conditioned space includes a programmed control device which produces a first signal for driving a fan inverter connected to the evaporator fan motor. A second signal, which is a function of the first signal, is also provided by the control device to drive a compressor inverter coupled to the compressor. A microprocessor having a program is operatively connected to the programmed control device for controlling its operation to effect the measured temperature of the conditioned space.
