WIRELESS CONTROLLER WITH GATEWAY
First Claim
1. A thermostat for use in controlling an HVAC system of a building or other structure, the building or other structure having a gateway for receiving one or more load shedding messages from a utility, the thermostat comprising:
- a user interface for allowing a user to interact with the thermostat;
a wireless transceiver for wirelessly communicating with the gateway of the building or other structure, wherein the gateway is located remotely from the thermostat;
a temperature sensor for sensing a temperature inside the building or other structure and for providing a signal related to the sensed temperature; and
a thermostat controller coupled to the user interface, the wireless transceiver and the temperature sensor, the thermostat controller having a control algorithm for controlling the HVAC system based, at least in part, on the signal provided by the temperature sensor, the control algorithm including a load shedding algorithm, wherein the thermostat controller employs the load shedding algorithm when the thermostat controller receives one or more load shedding messages from the remotely located gateway via the wireless transceiver.

Abstract
Remote control of energy consumption is realized using a readily installable, flexible approach. According to an example embodiment of the present invention, a remote source communicates with a wireless controller for executing energy usage control. The remote source sends signals to the wireless controller via a gateway located near or, in one implementation, forming part of the wireless controller. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump. With this approach, wired connections from the gateway to energy-consuming equipment do not necessarily need to be made in order to effect remote energy-consumption control. For instance, when used in connection with a controller wired to the energy-consuming equipment, the gateway need only communicate wirelessly with the controller and does not necessarily need to be coupled to the energy-consuming equipment. In addition, access to the energy-consuming equipment for establishing remote energy control is not necessary; rather, the remote energy control can be effected by accessing user-friendly locations, such as those where thermostats and other controllers are typically located.
