  • Patent number: 10152067
    Abstract: A thermostat for a climate control system includes an electronic memory in which at least three occupancy settings are stored. The occupancy settings including a pre-defined unoccupied temperature set-point associated with an unoccupied state, a pre-defined occupied temperature set-point associated with an occupied-awake state and a pre-defined sleep temperature set-point associated with an occupied-asleep state. The thermostat's microprocessor is configured to communicate with the memory, and to establish at least three time periods during the day. The microprocessor assigns to each time period one of at least three user-selectable occupancy states including an unoccupied state, an occupied-awake state and an occupied-asleep state.

  • Patent number: 9618227
    Abstract: Systems and methods of providing climate control and/or energy management in a structure having a networking thermostat. In some example embodiments the network is used to monitor a geographic location of a user device associated with a user of the structure. The monitoring may be performed to determine the location relative to a destination located apart from the structure. The network is used to control a set point of the thermostat based on the location. Additionally or alternatively, the monitoring may be performed to determine time period(s) during which the structure is unoccupied and the thermostat is set at a first set point. Energy savings that could have been realized by changing the first set point to a second set point are estimated and provided to the user.

  • Patent number: 8761944
    Abstract: A controller in communication with one or more energy consuming appliances for a premises includes a transmitter device for transmitting wireless signals to a utility meter to request an energy consumption reading, and a receiver device to receive wireless signals including energy consumption information. The controller is configured to receive a signal from an energy consuming appliance indicating the appliance was actuated, and to responsively transmit a signal to the utility meter to request an energy consumption reading and thereafter receive a signal including an energy consumption value. Following deactivation of the appliance, the controller is configured to transmit a signal to the utility meter to request an energy consumption reading, and thereafter receive a signal from the meter including another energy consumption value. The controller is configured to determine from a difference between the energy consumption values an estimate of the energy consumption level associated with the appliance.

  • Publication number: 20140163746
    Abstract: Disclosed herein are exemplary embodiments of apparatus and methods for determining and/or monitoring load of energy consuming appliances within a premises. In an exemplary embodiment, there is a thermostat for monitoring energy consumption associated with an HVAC unit having a compressor. The thermostat is configured to communicate information on energy consumption and/or information on duration of time of operation associated with the HVAC unit to a user. In another exemplary embodiment, there is a system for monitoring energy consumption for an energy consuming load in a premises that is supplied with power monitored by a utility meter. A gateway is in connection with the controller for enabling connection via the internet to a website. At least one of the gateway and the controller is configured to communicate information on energy consumption associated with the energy consuming load to an energy service provider and/or a consumer.

  • Patent number: 8016205
    Abstract: A thermostat is provided that includes a peripheral edge that, at least in part, defines an opening in the thermostat. The thermostat further includes a carbon monoxide sensor capable of sensing the presence of carbon monoxide gas in the ambient air near the thermostat, and providing a measurable output value that is indicative of the level of carbon monoxide gas. The thermostat also includes a replaceable battery that applies a voltage to the carbon monoxide sensor. The thermostat further includes a microprocessor disposed on a circuit board. The circuit board, sensor and battery are together disposed on or in the thermostat. The circuit board is configured to establish an electrical connection with the carbon monoxide sensor and the battery. The microprocessor is configured to periodically read the carbon monoxide sensor output, and to activate an audible alarm in a continuous manner to indicate an emergency upon detecting a carbon monoxide level that exceeds a predetermined value.
