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 be coupled to the
second port so as to communicate with one or more communicating
thermostats via a second network. The web server may provide one or more
web-pages via the first port that display a graphical floor plan of the
building, and permit a user to drag and drop individual building control
device images that correspond to the one or more building control devices
onto the floor plan.
