  • Patent number: 10627123
    Abstract: A thermostat for a building space includes a communication interface and a processing circuit. The communications interface is configured to communicate with one or more user devices and a master device. The processing circuit is configured to determine a master temperature setpoint based on input received from the master device via the communications interface and determine a non-master temperature setpoint based on input received from the one or more user devices via the communications interface. The processing circuit is configured to select one of the master temperature setpoint and the non-master temperature setpoint based on an operating mode of the thermostat. Based on the selected temperature setpoint, the processing circuit is configured to generate and provide control signals for building equipment. The control signals cause the building equipment to control an ambient temperature of the building space to the selected setpoint.

  • Patent number: 10619876
    Abstract: A device includes a memory configured to store a preexisting schedule and one or more processors configured to perform operations including controlling a temperature within an enclosure according to a first setpoint, wherein the first setpoint is from the preexisting schedule and represents a temperature for when the enclosure is occupied. The operations also include accessing occupancy data indicating occupancy within the enclosure and automatically changing the first setpoint to a second setpoint upon expiration of a predetermined time interval during which no occupancy has been detected. The second setpoint requires less energy to maintain than the first setpoint, and the predetermined time interval is modified based at least in part on received manual settings that indicate occupancy following the changing to the second setpoint.
