Abstract: A system for controlling an HVAC system and for monitoring energy usage at a premises is described. The system includes an energy meter at a electrical distribution panel, where the energy meter connected to one or more current transformers monitoring the current in one or more input lines and load lines and collecting current information for each of the monitored lines. The energy meter is further including a wireless radio to transmit the current information. An intelligent thermostat is operable to control the HVAC system at the premises according to environmental data sensed by the intelligent thermostat, and to receive the current information from the energy meter and to transmit the current information to a remote server for processing. A remote server is operable to process the current information from the energy meter by applying a scaling factor to the current information to determine energy usage. The remote server can also group the energy usage information according the load types being monitored.

Abstract: A system and method are described for conserving energy in HVAC systems. During certain temperature requests, ambient air can be supplied to a conditioned space and the HVAC compressor can be turned off to conserve power. During certain temperature requests, supply air can be adjusted through cycling of heating or cooling elements to conserve power and maintain desired space temperature. In various embodiments, supply air temperature, coil temperature, cabinet temperature and other values can be monitored for their effect on cooling and/or heating, and taken into account for determining how to best cool or heat a conditioned space.

Abstract: A networking thermostat is described that includes a main processor and a communications processor. The main processor includes a network manager function, a master messaging function and a slave messaging function while the communications processor includes a wireless radio enabling the thermostat to communicate with other networking thermostats. The networking thermostat is able to operate in a master mode or a slave mode, where the master mode allows the networking thermostat to act as a main gateway between other networking thermostats and a remote server. When in the master mode the networking thermostat can default to a slave if communication with the remote server is lost, thereby allowing one of the other networking thermostats to become a master.
