The main load control device may adjust the threshold based on line/load conditions of the multiple location load control system.
A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three- wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.
A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be configured to be mounted over an installed mechanical switch having a paddle actuator and may include a base and a control unit that is configured to be removably attached to the base. The base may include a frame, a clamp arm, a screw, and/or a sleeve. The clamp arm may be configured to secure the base to a protruding portion of the paddle actuator. The clamp arm may be attached to the frame at a pivot joint. The clamp arm may be configured to pivot about the pivot joint. The pivot joint may be located proximate to an endpoint or a midpoint of the frame.
A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g, capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g, capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).
A load control system may include a control device, such as a control-target device and a control-source device. A control circuit of a computing device(s) may execute a load control system configuration tool. The control circuit executing the load control system configuration tool may display first level details associated with the load control system in a project. The first level details may include one or more of square footage, energy code, building function, or construction type associated with the project. Based on the first level details, the control circuit of the computing device(s) executing the load control system configuration tool may generate one or more load control system configurations. Each one of the one or more load control system configurations may include one or more load control instructions. The one or more load control instructions may control the control -target devices in the load control system in the project.
A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may switch from controlling one characteristic of the electrical loads to controlling another characteristic of the electrical loads based on the position of one or more components of the load control device. Such a position may be manipulated by moving the one or more components relative to an idle position of the load control device. The load control device may be a wall-mounted device or a battery-powered remote control device.
A control device configured for use in a load control system to control an external electrical load may provide simple feedback regarding the operation of the control device. For example, the control device may comprise a base portion configured to be mounted to an electrical wallbox or over a mechanical switch, and a control unit connected to the base portion. The control unit may comprise a rotation portion rotatable with respect to the base portion, an actuation portion, and a light source. The control unit may be configured to control the light source to illuminate at least an illuminated portion of the actuation portion in response to actuations of the rotation portion and the actuation portion. In addition, the control unit may provide a limit indication on the illuminated portion by blinking the illuminated portion when the electrical load has reached a limit.
Systems and methods are disclosed for communicating via a communications network with a load control system of a respective user environment, receiving information on the load control system via the communications network, displaying graphical user interfaces based on the received information, and controlling and configuring the load control system via graphical user interfaces by communicating via the communications network messages the load control system.
Color temperature in a space may be adjusted by controlling lighting control devices and motorized window treatments. A position of a motorized window treatment may be controlled based on a control mode or user preference. Outside color temperature values may be limited from entering the space by closing the shade fabric of the motorized window treatment when the outside color temperature exceeds a threshold. A color temperature of outside light entering the space may be determined after the shades are adjusted. The color temperature of outside light entering the space may be determined by considering the shade fabric characteristics. The color temperature of light emitted by one or more lighting fixtures may be adjusted based on the color temperature of the light entering the space.
