Abstract:
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; 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; a thermostat housing and a thermostat base, wherein the thermostat housing is removably coupled to the thermostat base such that when the thermostat housing is coupled to the thermostat base, one or more electrical signals can be communicated between the thermostat housing and the thermostat base; and the thermostat housing carrying the user interface, the temperature sensor and the thermostat controller, and the thermostat base carrying the wireless transceiver.
