Abstract

A control system is provided for automatically setting up and controlling a climate control system for a building having one or more zones and one or more thermostats in communication with the associated heating or cooling components of the climate control system. In some embodiments, the climate control system comprises one or more heating or cooling systems which may be controlled by one or more thermostats. In other embodiments, the climate control system comprises a thermostat, a heating and cooling system, one or more remote temperature sensors corresponding to at least some of the one or more zones within the building, and one or more dampers corresponding to at least some of the one or more zones within the building.

Claims

1. A climate control system for conditioning one or more zones within a building having a heating or cooling system, the climate control system comprising:

one or more dampers corresponding to at least some of the one or more zones within the building, where each damper controllably permits the flow of conditioned air to at least one of the zones;

one or more remote temperature sensor devices disposed in at least some of the one or more zones within the building; and

a thermostat having a local temperature sensor, the thermostat being adapted to communicate with the heating and cooling system and one or more remote temperature sensors, wherein the thermostat includes a set-up mode that initiates the operation of the heating or cooling system and responsively assigns to the thermostat each remote temperature sensor device that detect a temperature change corresponding with temperature change sensed by the local temperature sensor.

2. The control system of claim 1 wherein the thermostat initiates the operation of the heating or cooling system and successively operates each of the one or more damper devices, such that the thermostat may responsively assign each damper device that causes an assigned remote temperature sensor to detect an associated temperature change corresponding to the opening or closing of the particular damper device.

3. The climate control system of claim 2, wherein the dampers are initially closed and the thermostat successively opens each of the one or more damper devices, such that the thermostat may responsively assign each opened damper device that causes an assigned remote temperature sensor to detect an associated temperature change corresponding to the particular damper device.

4. The climate control system of claim 2 wherein the thermostat stores identifying information for the assigned heating or cooling system, assigned remote temperature sensors, and assigned damper devices in memory.

5. A climate control system adapted to control a heating or cooling system for conditioning one or more zones within a building, the climate control system comprising:

one or more remote temperature sensor devices disposed in one or more zones within a building, being configured to detect sensed temperature information for the zone in which remote temperature sensor device is disposed, wherein each of the one or more remote temperature sensor devices is initially unassigned to any thermostat; and

a thermostat in communication with the one or more remote temperature sensors, the thermostat being configured to initiate operation of the heating or cooling system, and to receive sensed temperature information from the one or more remote temperature sensors and sensed temperature information from a local temperature sensor disposed within the thermostat, wherein the thermostat is further configured to assign to the thermostat each remote temperature sensor device that detects a temperature change which corresponds with a temperature change sensed by the local temperature sensor.

6. The climate control system of claim 5, wherein the thermostat is configured to assign to the thermostat each remote temperature sensor device that detects a temperature change within a given time period that corresponds with the temperature change sensed by the local temperature sensor.

7. The climate control system of claim 6, wherein the temperature change is an increase of a predetermined number of degrees within a given time period during which operation of the heating system is initiated.

8. The climate control system of claim 6, wherein the temperature change is a decrease of a predetermined number of degrees within a given time period during which operation of the cooling system is initiated.

9. The climate control system of claim 5, wherein the thermostat is configured to initiate heating operation and to assign to the thermostat each remote temperature sensor device that detects a temperature change of an increase of a predetermined number of degrees that corresponds with the temperature change sensed by the local temperature sensor.

10. The climate control system of claim 5, wherein the thermostat is configured to initiate cooling operation and to assign to the thermostat each remote temperature sensor device that detects a temperature change of a decrease of a predetermined number of degrees that corresponds with the temperature change sensed by the local temperature sensor.

11. The climate control system of claim 5, further including one or more dampers configured to be controllably opened to permit the flow of conditioned air to the one or more zones in the building respectively, the thermostat being configured to initiate operation of the heating or cooling system and to open only one of the one or more dampers to permit flow of conditioned air to only one zone, wherein the thermostat is configured to identify a temperature change detected by one of the remote temperature sensor devices and responsively assign the open damper to the thermostat such that the thermostat controls the operation of the assigned damper to provide conditioned air to the zone containing the corresponding remote temperature sensor device.

12. The climate control system of claim 11, wherein the thermostat successively opens each of the one or more damper devices, such that the thermostat may responsively assign each open damper device that causes an assigned remote temperature sensor to detect an associated temperature change corresponding to the particular damper device.
