Abstract

An HVAC control system that accommodates and/or facilitates control from a remote location. The HVAC control system may include a web-enabled building control appliance that has a controller, a first port and a second port. The controller may implement a web server that is coupled to the first port for serving up one or more web pages on a first network and for receiving a number of responses. The controller may also be coupled to the second port so as to communicate with one or more communicating thermostats via a second network. The web server may be adapted to provide one or more web-pages via the first port that solicit information including schedule and/or non-schedule thermostat configuration information, and for receiving the information via one or more of the responses.

Claims

1. A web enabled building control appliance, comprising:

a controller;

a first port coupled to the controller, the first port can communicate over a first network;

a web server implemented by the controller and coupled to the first port for serving up one or more web-pages on the first network via the first port and for receiving a number of responses;

a second port coupled to the controller, the second port can be coupled to one or more thermostats via a second network, wherein each of the one or more thermostats can communicate with the controller over the second network via the second port;

the web server configured to provide one or more web-pages via the first port that solicit information including;

user information for defining each of a plurality of users;

one or more settings for each of the one or more thermostats;

the web server further configured to receive the information via one or more of the responses, and in response, to configure the web server to provide the plurality of users with access to the one or more settings of one or more of the thermostats that are coupled to the second port.

2. The web enabled building control appliance of claim 1, wherein the second port is configured to be coupled to two or more thermostats via the second network.

3. The web enabled building control appliance of claim 1, wherein the controller provides at least some of the information solicited by the one or more web-pages to at least selected ones of the one or more thermostats via the second network.

4. The web enabled building control appliance of claim 1, wherein the web server provides one or more web-pages that solicit information including non-schedule thermostat configuration information for each of the one or more thermostats.

5. The web enabled building control appliance of claim 4, wherein the controller provides at least some of the non-schedule thermostat configuration information solicited by the one or more web-pages for each of the one or more thermostats to corresponding ones of the one or more thermostats via the second network.

6. The web enabled building control appliance of claim 1, wherein the web server provides one or more web-pages via the first port that display status information.

7. The web enabled building control appliance of claim 6, wherein the status information includes a current set point and a current setback state of at least one of the one or more thermostats.

8. The web enabled building control appliance of claim 1, wherein the web server provides one or more web-pages via the first port that solicit temperature scheduling information, and for receiving temperature scheduling information via one or more of the responses.

9. The web enabled building control appliance of claim 1, wherein the one or more web-pages provided by the web server that solicit information include a number of predetermined configuration options for selection by the user.

10. The web enabled building control appliance of claim 9, wherein at least some of the number of predetermined configuration options are presented in a pull-down menu.

11. The web enabled building control appliance of claim 9, wherein the number of predetermined configuration options include one or more of a thermostat model option, a number of cooling stages option and a number of heating stages option.

12. The web enabled building control appliance of claim 1, wherein at least some of the received information is downloaded from the controller to one or more of the thermostats via the second network.

13. The web enabled building control appliance of claim 1, wherein the controller receives sensor information from the one or more thermostats via the second network.

14. The web enabled building control appliance of claim 13, wherein the controller is programmed with a control algorithm that issues commands to the one or more thermostats via the second network to activate or deactivate HVAC equipment that is connected to the one or more thermostats, based at least in part on one or more of the received sensor information.

15. The web enabled building control appliance of claim 1, wherein at least one of the one or more thermostats has a controller that is capable of issuing commands to HVAC equipment that is connected to the at least one thermostat, based at least in part on a programmed local schedule, but the programmed local schedule of the at least one thermostat is not used in favor of a programmable schedule of the web-enabled building control appliance.

16. The web enabled building control appliance of claim 1, wherein the controller automatically discovers at least one of the one or more thermostats on the second network.

17. The web enabled building control appliance of claim 1, wherein the controller is programmed with a control algorithm that issues commands to the one or more thermostats via the second network to activate or deactivate HVAC equipment that is connected to the one or more thermostats, based at least in part on the temperature schedule.

18. The web enabled building control appliance of claim 1, wherein the web server is further configured to provide one or more web pages via the first port that solicits information related to a temperature schedule, and to receive the information via one or more of the responses, wherein at least some of the information related to the temperature schedule is downloaded from the controller to one or more of the thermostats via the second network.
