Abstract
A thermostat has a thermostat housing that includes circuitry to control HVAC equipment and first and second dampers, and a first temperature sensor. A second temperature sensor is operatively connected to the thermostat, and a microcomputer enables the thermostat to perform the following steps: receiving a desired temperature; receiving first and zone temperatures; activating or de-activating the heating and cooling equipment responsive to a comparison between the first zone temperature relative to the desired temperature; and adjusting the first and second dampers as required to direct airflow to the first and second zones to adjust the second temperature until it is equal to or within an allowed deviation of the first temperature.
