Various systems and method related to home automation systems are presented. A service robot system may be present that includes a service robot that autonomously moves within a structure to perform a household task. The service robot system may include a wireless communication interface, wherein the service robot system is configured to transmit, via the wireless communication interface, an indication of robot activity indicative of the service robot moving within the structure. Such a home automation system may also include a home security system that includes one or more motion sensors that detect motion within a structure. The home security system may be configured to distinguish intrusion activity (e.g., a burglar) from robot activity based at least in part on the indication of robot activity.

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.

Thermostat user interface

The current application is directed to intelligent controllers that use sensor output and electronically stored information, including one or more of electronically stored rules, parameters, and instructions, to determine whether or not one or more types of entities are present within an area, volume, or environment monitored by the intelligent controllers. The intelligent controllers select operational modes and modify control schedules with respect to the presence and absence of the one or more entities. The intelligent controllers employ feedback information to continuously adjust the electronically stored parameters and rules in order to minimize the number of incorrect inferences with respect to the presence or absence of the one or more entities and in order to maximize the efficiency by which various types of systems controlled by the intelligent controllers carry out selected operational modes.

The disclosure provides systems and methods of use of an HVAC graphical interface dashboard. In various embodiments the dashboard includes a weather tab, wherein invoking the weather tab advances to a weather screen. The dashboard also includes an indoor humidity tab, wherein invoking the indoor humidity tab advances to a humidity screen which displays at least a current indoor humidity, wherein the humidity screen interprets a percentage of humidity for a user. A programs tab and a home tab are also provided. A button of the dashboard turns a color, such as an inverse color, when it is touched.

A motor-driven compressor includes a compression unit, an electric motor, a housing, a cover, wherein the cover includes a main body and a connector coupler, and the cover and the housing define an accommodating chamber, a motor driving circuit that is accommodated in the accommodating chamber and includes a circuit board, and a metal terminal held in the connector coupler, wherein the metal terminal includes first and second end portions. The cover has a shield including a first shield portion, which blocks electromagnetic noise and forms at least part of the connector coupler, and a second shield portion, which blocks electromagnetic noise and forms at least part of the main body. The first and second shield portions are coupled to each other. The second shield portion includes an insertion hole into which one of the first and second end portions of the metal terminal is insertable.

Motor-driven compressor

A method for configuring a controller for an HVAC system. The method comprises providing a closed loop refrigerant system and a control system to control the closed loop refrigerant system. The control system comprises a controller, an input device, and a processor including a signal sensing circuit. The input device is activated to provide one or more signals to the controller to control the components of the closed loop refrigerant system. One or more signals are sensed with the signal sensing circuit to determine whether signals are present between the input device and the controller. The signals are processed with the processor to determine what type of closed loop refrigerant system is present. The controller is then configured to control the type of system determined by the processor.

Method and apparatus to sense and establish operation mode for an hvac control

A heating control method is provided for a multi-stage heating system including a heating circuit having a compressor, a condenser and an evaporator. An auxiliary heater is provided that is selectively controlled independently of the heating circuit. During a heating cycle in which the ambient outside temperature is greater than the balance point temperature associated with the operation of the heating circuit, the auxiliary heating circuit is normally prevented from operating. However, if the heating requirements are not satisfied after a predetermined time or the compressor is non-functional or operating improperly, the auxiliary heater is enabled.

Method and apparatus to prevent low temperature damage using an hvac control

An HVAC system and method for configuring a controller to control a compressor including a detection system provided to determine a type of compressor. The detection system includes a processor; and a load sensing circuit connected between the processor and a controller. The controller has a plurality of output connections connectable to a compressor. The load sensing circuit senses whether a load is present on each output connection of the plurality of output connections and provides a load signal to the processor indicating whether a load is present on each output connection. The load signals are processed with the processor to determine the type of compressor is present. The controller is configured to control the compressor in response to the determined type of compressor.

Method and apparatus to sense and control compressor operation in an hvac system

An HVAC&R system is disclosed that utilizes energy-efficient valving. The valving controls the flow of refrigerant and may be adapted for evaporator or condenser applications, on both AC systems and heat pumps (as well as chillers and other refrigeration systems). The valving may provide simultaneous and individualized control of flow through individual coils or groups of coils for improved control of evaporation, condensation, defrosting and so forth. In some configurations a common sensor may be shared between individual coils or groups of coils and may provide sensed parameters to control circuitry for controlling the valving. Other configurations may include bypass valving to direct fluid around the flow control valving. In yet other configurations, a valve may be used to bypass tapped vapor around a heat exchanger functioning as an evaporator.
