1. A control adapted to be mounted in a heating and cooling system having a combustion air blower, a gas valve, an igniter, a compressor relay and a circulating air blower, the control comprising:

  • a receiver means for receiving transmitted sensed temperature and temperature set point information from one or more remote temperature sensors within the space;

    a plurality of switching means for switching power to the combustion air blower, igniter, gas valve and circulating air blower to establish heating operation;

    a plurality of switching means for switching power to the compressor relay and circulation air blower to establish cooling operation; and

    a microcomputer for receiving transmitted temperature information from the one or more remote temperature sensors and for controlling the plurality of switching means, wherein the microcontroller responsively controls the plurality of switching means to establish heating operation when at least one remote temperature sensor transmits a sensed temperature that is more than a predetermined amount below a desired heating set point temperature, and responsively controls the plurality of switching means to establish cooling operation when at least one remote temperature sensor transmits a sensed temperature that is more than a predetermined amount above a desired cooling set point temperature.
