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 having 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 an overview or summary web-page via the first port that displays information regarding the one or more thermostats, where the information that is displayed may be customized for a particular user.

7. The web enabled building control appliance of claim 6, wherein the information that is displayed on the summary web-page is limited to information regarding thermostats that are assigned to the particular user.

8. The web enabled building control appliance of claim 1, wherein the information that is displayed on the summary web-page is selected in accordance with a technical proficiency and/or a desired responsibility of the particular user.

9. The web enabled building control appliance of claim 8, wherein the particular user is a tenant of a space of a building, and one or more of the thermostats are located in the tenant'"'"'s space of the building, and wherein the information displayed on the summary web-page is limited to information that corresponds to the one or more thermostats are located in the tenant'"'"'s space of the building.

10. The web enabled building control appliance of claim 8, wherein the particular user may be an HVAC contractor and the information displayed on the summary web-page may include configuration and/or setup information.

11. The web enabled building control appliance of claim 1 wherein the information that is displayed on the summary web-page includes one or more of a thermostat identifier for one or more of the thermostats, a current inside temperature reported by one or more of the thermostats, a current outside temperature, a current set point for one or more of the thermostats, a schedule related parameter for one or more of the thermostats, a humidity related parameter that is reported by one or more of the thermostats, a current operating mode of HVAC equipment that is connected to one or more of the thermostats, an alarm related parameter for one or more of the thermostats, a discharge air temperature of HVAC equipment that is connected to one or more of the thermostats, a plenum related pressure of HVAC equipment that is connected to one or more of the thermostats, a relay output related parameter of HVAC equipment that is connected to one or more of the thermostats, a lockout status of HVAC equipment that is connected to one or more of the thermostats;

a fan switch status of HVAC equipment that is connected to one or more of the thermostats, a throttle range of one or more of the thermostats, an integral time of one or more of the thermostats, a derivative time of one or more of the thermostats, and an anticipator authority of one or more of the thermostats.

12. The web enabled building control appliance of claim 1 wherein the information that is displayed on the summary web-page includes two or more parameters or settings, wherein each parameter or setting is displayed in a corresponding column in the summary web-page.

13. The web enabled building control appliance of claim 1 wherein the information that is displayed on the summary web-page includes two or more parameters or settings, wherein each parameter or setting is displayed in a corresponding column in the summary web-page, and wherein at least some of the parameters or settings include a hyperlink that, when selected, the web enabled building control appliance displays another web-page that includes additional information that is related to the selected parameter or setting.

14. A method of providing a summary web-page for a web-based HVAC control system having one or more HVAC control devices, the method comprising the steps of:
