A climate control system having a heating and cooling unit is provided
that includes one or more remote temperature sensors for transmitting
sensed temperature, a combustion air blower, a burner, an igniter, a gas
valve, a compressor relay and circulating air blower. A control mounted
on the heating and cooling unit has a receiver for receiving the
transmitted information, a plurality of switching devices for switching
power to the combustion air blower, igniter, gas valve and circulating
air blower to establish heating operation, and a plurality of switching
devices for switching power to the compressor relay and circulation air
blower to establish cooling operation. The control responsively controls
the plurality of switching devices to establish heating operation where
the sensed temperature of at least one remote sensor is below the heating
set point, or to establish cooling operation when at a sensed temperature
is above the cooling set point.
