1. A wall mountable thermostat having a housing assembly for use in controlling an HVAC system of a building or other structure, the building or other structure having a local gateway coupled to a communications network, the thermostat comprising:

  • a user interface for allowing a user to interact with the thermostat;

    a wireless transceiver in the housing assembly for wirelessly communicating with the local gateway of the building or other structure, wherein the local 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 one or more control parameters, the thermostat controller configured to receive an electrical signal from the wireless transceiver to allow a user to control the HVAC system as a function of user inputs received from a remote location on the communications network via the local gateway and the wireless transceiver separate from any utility based control application, to override user inputs received via the user interface.
