Abstract

A system that allows a contractor to remotely monitor and/or interact with its customers' building control systems, such as heating, ventilating and air conditioning (HVAC) systems, and analyze information obtained from the building control systems over time. Such a system may help the contractor monitor and diagnosis customer building control systems, setup service calls, achieve better customer relations, create more effective marketing opportunities, as well as other functions. In some cases, the disclosed system may help a contractor pro-actively identify possible issues with its customer's building control systems, and only then schedule maintenance as required. In some cases, based on the analysis of information obtained from the building control systems over time, the system may output indications of abnormalities in the operation of the building control systems from which information may be received.

First claim

What is claimed is:

1. A remote contractor system communicates with a plurality of client heating, ventilation, and air conditioning (HVAC) controllers over a network, wherein each of the client HVAC controllers is part of a corresponding client HVAC system that services a corresponding client building, the remote contractor system including a plurality of client accounts wherein each of the client HVAC systems corresponds to a particular client account, the remote contractor system comprising:
a communications port operatively communicates with a plurality of client HVAC controllers, and receives data related to the operation of a plurality of client HVAC systems;
a memory for storing the received data related to the operation of the plurality of client HVAC systems;
a controller operatively coupled to the memory, wherein the controller includes a processor for processing at least some of the received data related to the operation of the plurality of client HVAC systems and to:
identify one or more trends over time using the received data from two or more of the client HVAC systems, wherein the one or more trends includes a trend over a period of time in one or more of humidity level, temperature level, fan activation, and particle count;
based on the identified one or more trends, identify one or more abnormalities in the operation of a particular one of the client HVAC systems using the received data;
generate an alert for one or more of the abnormalities in the operation of the particular one of the client HVAC systems;
associate the alert with the client account that corresponds to the particular one of the client HVAC systems; and
provide easy access to the alert via the client account that corresponds to the particular one of the client HVAC systems.

2. The remote contractor system of claim 1 , wherein the controller repeatedly identifies one or more trends over time based on the received data related to operation of the plurality of client HVAC systems.

3. The remote contractor system of claim 1 , wherein the controller also outputs an expected cause of the identified one or more abnormalities in the operation of the particular one of the client HVAC systems.

4. The remote contractor system of claim 3 , wherein the expected cause of the identified abnormalities is a degradation or failure of one or more HVAC components of the particular one of the client HVAC systems.

5. The remote contractor system of claim 4 , wherein the expected cause of the identified one or more abnormalities is a degradation or failure of one or more HVAC components other than an air filter of the particular one of the client HVAC systems.

6. The remote contractor system of claim 3 , wherein the expected cause of the identified one or more abnormalities is related to a structure that is serviced by the particular one of the client HVAC systems and not one or more HVAC components of the particular one of the client HVAC systems.

7. The remote contractor system of claim 1 , wherein the controller further outputs a suggested solution for fixing the identified one or more abnormalities.

8. The remote contractor system of claim 7 , wherein the suggested solution comprises a suggestion to replace one or more identified HVAC components of the particular one of the client HVAC systems.

9. The remote contractor system of claim 7 , wherein the plurality of client heating, ventilation, and air conditioning (HVAC) controllers are programmable HVAC controllers, and the suggested solution comprises a suggestion to reprogram the client HVAC controller that corresponds to the particular one of the client HVAC systems in a way identified by the suggested solution.

10. The remote contractor system of claim 7 , wherein the suggested solution comprises a suggestion to modify a building configuration of the client building that is serviced by the particular one of the client HVAC systems.

11. The remote contractor system of claim 1 , wherein the controller outputs a plurality of reports of alerts over time, wherein each of the plurality of reports presents results in a consistent format.

12. The remote contractor system of claim 11 , wherein the controller formats the plurality of reports differently for each of a first audience and a second audience.

13. The remote contractor system of claim 1 , wherein the controller processes the at least some of the received data related to the operation of a first client HVAC system to identify one or more trends in the operation of the first client HVAC system over time, and based on the identified one or more trends in the operation of the first client HVAC system over time, identify one or more abnormalities in the operation of the first client HVAC system.

14. The remote contractor system of claim 1 , wherein the two or more client HVAC systems from which the one or more trends are identified are associated with client buildings that have similar building characteristics.

15. The remote contractor system of claim 1 , wherein the two or more client HVAC systems from which the one or more trends are identified are each associated with client buildings that have occupants with lifestyle characteristics that are similar.

16. A remote contractor system communicates with a plurality of client heating, ventilation, and air conditioning (HVAC) controllers, wherein each of the HVAC controllers is for controlling one or more HVAC components of a corresponding client HVAC system, the remote contractor system including a plurality of client accounts wherein each of the client HVAC systems corresponds to a particular client account, the remote contractor system comprising:
a communications port for sending and/or receiving data related to the operation of two or more HVAC systems;
a memory for storing information comprising the received data related to the operation of the two or more HVAC systems;
a controller operatively coupled to the communications port and the memory; and
wherein the controller:
processes at least some of the received data related to the operation of the two or more HVAC systems to identify one or more trends, wherein the one or more trends includes a trend over a period of time in one or more of humidity level, temperature level, fan activation, and particle count;
identifies one or more abnormalities in the operation of a particular HVAC system based on the processing of the received data related to the operation of the two or more HVAC systems;
generates an alert for one or more of the identified abnormalities in the operation of the particular HVAC system, along with one or more suggested causes of the identified one or more abnormalities in the operation of the particular HVAC system;
associates the alert with the client account that corresponds to the particular one of the client HVAC systems; and
provides easy access to the alert via the client account that corresponds to the particular one of the client HVAC systems.

17. The remote contractor system of claim 16 , wherein the controller identifies in the alert one or more previously successful solutions for curing the identified one or more abnormalities in the operation of the particular HVAC system.

18. A remote contractor system comprising:
a communications port for sending and/or receiving data related to operation of two or more heating, ventilation, and air conditioning (HVAC) controllers of two or more HVAC systems;
a memory for storing the received data related to the operation of the two or more HVAC systems;
a controller operatively coupled to the communications por
