Abstract
An electronic thermostatic control for a heat/cool air conditioning unit and with variable temperature anticipation useful when the unit is located above or below the room's normal zone to compensate for different effects of air stratification as between heat and cool operating modes. A comparator circuit output switches the compressor on and off and a portion of the comparator output is fed back to one of the comparator inputs to effect a degree of temperature anticipation. The feedback is altered by a load impedance switch and into and out of the comparator output circuit to vary the voltage swing on the comparator output and thus to vary the feedback. The amount of alteration of the feedback is selected to achieve the desired variation of temperature anticipation between heating and cooling operating modes.
