  • Patent number: 9655268
    Abstract: An operating control unit for an electrical appliance with an operating field is mounted on an underside of the operating field. The operating control unit includes a frame body, a flat component carrier being mounted to the frame body from behind and having piezo-active sensor elements, and a back support mounted to a back side of the frame body and enclosing the component carrier. The operating control unit has after pre-assembly two different assembly states. In a pre-mount state the back support is fixed to the frame body enclosing the component support, and some locking means of the frame body are formed as pre-mount locking means and are holding the back support against disassembly. In a final-assembly state the back support is pressed against the frame body with less distance between the two, and final-assembly locking means of the frame body are holding the back support in a closer position than the pre-mount locking means.

    Abstract: A room heater is controlled according to a difference between a detected temperature detected by a first room-temperature detector and a predetermined set temperature. When a detected temperature detected by a second room-temperature detector falls below a first reference temperature, the operation is started on receiving an on-command from a thermostat. When the detected temperature by the second room-temperature detector has raised above a second reference temperature which is set higher than the first reference temperature, the operation is stopped on receiving an off-command from the thermostat. The room heater is controlled to raise a set temperature by a predetermined value if it does not receive the off-command by passing of a first predetermined period of time after having received the on-command or if the detected temperature detected by the first room-temperature detector has been at the set temperature or higher without receiving the off-command for a second predetermined period of time.

  • Patent number: 8870087
    Abstract: An environmental control device is disclosed and includes a temperature sensor, an audio module, an input/out module operatively connected to an environmental system, a memory module, and a processor in communication with the temperature sensor, the audio module, and the memory. The memory stores a control routine comprising processor executable instructions and an audio file associated with a predefined event related to the environmental system. The processor executable instructions are configured to receive a current state signal corresponding to one of a temperature sensor signal from the temperature sensor and an environmental system output signal from the input/output module, determine whether the current state signal corresponds to the predefined event, and generate, via the audio module, an audible signal based on the audio file in response to determining that the current state signal corresponds to the predefined event.

  • Patent number: 8868219
    Abstract: A thermostat for controlling an HVAC system is described, the thermostat having a user interface that is visually pleasing, approachable, and easy to use while also providing ready access to, and intuitive navigation within, a menuing system capable of receiving a variety of different types of user settings and/or control parameters. For some embodiments, the thermostat comprises a housing, a ring-shaped user-interface component configured to track a rotational input motion of a user, a processing system configured to identify a setpoint temperature value based on the tracked rotational input motion, and an electronic display coupled to the processing system. An interactive thermostat menuing system is accessible to the user by an inward pressing of the ring-shaped user interface component. User navigation within the interactive thermostat menuing system is achievable by virtue of respective rotational input motions and inward pressings of the ring-shaped user interface component.

  • Patent number: 8850348
    Abstract: Methods and devices for controlling a heating, ventilation, and air conditioning (HVAC) system by a thermostat are provided. Input can be received from a user via a thermostat, the input being indicative of an adjustment of an HVAC-related setting. On a real-time basis, the HVAC-related setting that is being adjusted can be compared against a feedback criterion designed to indicate a circumstance under which feedback is to be presented to the user. The circumstance can be indicative of an achievement of a HVAC-related setting of a predetermined responsibility level with respect to an energy usage of the HVAC system. Upon a real-time determination that the feedback criterion is satisfied, visual feedback can be caused to be presented to the user in real-time. The real-time feedback can include a visual icon having a visual appeal corresponding to a desirability of the satisfaction of the feedback criterion.

  • Patent number: 8770491
    Abstract: A thermostat includes a plurality of HVAC (heating, ventilation, and air conditioning) wire connectors including a connection to at least one call relay wire. The thermostat may also include a powering circuit, including a rechargeable battery, which is configured to provide electrical power to the thermostat by power stealing from a selected call relay wire. The power stealing may comprise an active power stealing mode, in which power is taken from the same selected call relay wire that is used to call for an HVAC function, and an inactive power stealing mode in which, in which no active call is being made. The powering circuit may be configured to substantially suspend (or at least reduce the level of) power stealing for at least a first time period following each transition of the thermostat from between operating states.

  • Patent number: 8757507
    Abstract: A thermostat for controlling an HVAC system and related systems, methods, and computer program products for facilitating user-friendly installation of the thermostat are described. For one embodiment, automated installation verification is performed by the thermostat by automatically sensing which wires have been inserted, selecting a candidate HVAC operating function (e.g., heating or cooling) that is consistent with a subset of HVAC signal types indicated by the inserted wires, applying control signals to the HVAC system to invoke that HVAC operating function, and processing a time sequence of acquired temperature readings to determine whether that HVAC operating function was successfully carried out. For one embodiment, the initial automated testing of the heating and cooling functions are only carried out at times for which such heating or cooling function would normally be invoked during normal operation of the thermostat. Automated determination of a heat pump call convention is also described.
