Abstract

A number of methods for testing an HVAC system for a building structure from a remote location outside of the building structure are disclosed. Generally, the HVAC system has a primarily active component and a primarily dormant component. The method includes the steps of transmitting a test request to the HVAC system from the remote location, performing a test on the primarily dormant component of the HVAC system in response to the test request, and producing a test result. The test result can then be transmitted to a location outside of the building structure.

First claim

What is claimed is:

1. An HVAC controller for controlling an HVAC system that services a space of a building, comprising:
an input/output port for sending and/or receiving information to and from outside the building;
a memory;
a controller operatively coupled to the input/output port and the memory, the controller configured to send and/or receive information via the input/output port to/from one or more HVAC components of an HVAC system to perform a test using the HVAC system that produces a test result, the controller configured to transmit the test result to a remote computer outside the building for analysis, the controller configured to receive the analysis of the test result from the remote computer via the input/output port, the controller is further configured to identify an expected time when the space serviced by the HVAC system is expected to be unoccupied, and to perform the test during the identified expected unoccupied time; and
wherein the HVAC system includes a heating component and a cooling component, the heating component being active during a heating season and the cooling component being active during a cooling season, wherein the test activates a dormant component of the HVAC system, the dormant HVAC component being the heating component during the cooling season and the cooling component during the heating season.

2. The HVAC controller of claim 1 , wherein the test is a self-test performed by the controller.

3. The HVAC controller of claim 2 , wherein the self-test is initiated by the remote computer outside the building via the input/output port.

4. The HVAC controller of claim 1 , wherein the test produces a test result that is related to a heating capacity and/or a cooling capacity of the HVAC system.

5. The HVAC controller of claim 1 , wherein the space includes a thermal mass, and the test produces a test result that is related to an effect of the HVAC system on the thermal mass.

6. The HVAC controller of claim 1 , further comprising a display.

7. The HVAC controller of claim 1 , wherein the HVAC system includes a heating component and a cooling component, the heating component being active during a heating season and the cooling component being active during a cooling season, wherein the test activates a dormant component of the HVAC system, the dormant HVAC component being the heating component during the cooling season and the cooling component during the heating season.

8. An HVAC controller for controlling an HVAC system that services a space of a building, comprising:
an input/output port for sending and/or receiving information to and from outside the building;
a memory;
a controller operatively coupled to the input/output port and the memory, the controller configured to send and/or receive information via the input/output port to/from one or more HVAC components of an HVAC system to perform a test using the HVAC system that produces a test result, the controller configured to transmit the test result to a remote computer outside the building for analysis, the controller configured to receive the analysis of the test result from the remote computer via the input/output port, the controller is further configured to identify an expected sleep time when the occupants of the space are expected to be sleeping in the space, and to perform the test during the identified expected sleep time; and
wherein the HVAC system includes a heating component and a cooling component, the heating component being active during a heating season and the cooling component being active during a cooling season, wherein the test activates a dormant component of the HVAC system, the dormant HVAC component being the heating component during the cooling season and the cooling component during the heating season.

9. The HVAC controller of claim 8 , wherein the test is a self-test performed by the controller.

10. The HVAC controller of claim 9 , wherein the self-test is initiated by the remote computer outside the building via the input/output port.

11. The HVAC controller of claim 8 , wherein the test produces a test result that is suitable for evaluating a heating capacity and/or a cooling capacity of the HVAC system.

12. The HVAC controller of claim 8 , wherein the space includes a thermal mass, and the test produces a test result that is suitable for evaluating an effect of the HVAC system on the thermal mass.

13. The HVAC controller of claim 8 , wherein the HVAC system includes a heating component and a cooling component, the heating component being active during a heating season and the cooling component being active during a cooling season, wherein the test activates a dormant component of the HVAC system, the dormant HVAC component being the heating component during the cooling season and the cooling component during the heating season.

14. The HVAC controller of claim 8 , further comprising a display.
