A method comprises measuring a light intensity at a window; determining if the light intensity exceeds a cloudy-day threshold; operating in a sunlight penetration limiting mode to control the motorized window treatment to control the sunlight penetration distance in the space; enabling the sunlight penetration limiting mode if the light intensity is greater than the cloudy-day threshold; and disabling the sunlight penetration limiting mode if the total lighting intensity is less than the cloudy-day threshold. The cloudy-day threshold is maintained at a constant threshold if a calculated solar elevation angle is greater than a predetermined solar elevation angle, and the cloudy-day threshold varies with time if the calculated solar elevation angle is less than the predetermined solar elevation angle. The cloudy-day threshold is a function of the calculated solar elevation angle if the calculated solar elevation angle is less than the predetermined solar elevation angle.

Method of controlling a motorized window treatment

A load control system may include control devices for controlling power provided to an electrical load. The control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. The control devices may include a load control discovery device capable of sending discovery messages configured to discover control devices within a location. The discovered control devices may be organized by signal strength and may be provided to a network device to enable association of the discovered control devices within a location. The discovery messages may be transmitted within an established discovery range. The discovery range may be adjusted to discover different control devices. Different control devices may be identified as the load control discovery device for discovering different control devices.

Commissioning load control systems

A system includes a window treatment adjacent to a window of a room. At least one motor drive unit is associated with the window treatment, for varying the position of the window treatment. A sensor measures a light level (e.g., an outdoor light level) at the window. A controller provides signals to the motor drive unit to automatically adjust the position of the window treatment so as to control a penetration distance of sunlight into the room when the window treatment is partially opened. The controller is configured to position the window treatment in a bright override position if the measured light level is at least a bright threshold value. The controller is configured to select the bright threshold value from among at least two predetermined values. The selection depends on an angle of incidence between light rays from the sun and a surface normal of the window.

Window treatment control using bright override

A load control system may comprise load control devices for controlling respective electrical loads, and a system controller operable to transmit digital messages including different commands to the load control devices in response to a selection of a preset. The different commands may include a preset command configured to identify preset data in a device database stored at the load control device and/or a multi-output command configured to define the preset data for being stored in the device database. The system controller may decide which of the commands to transmit to the load control devices in response to the selection of the preset.

Digital messages in a load control system

A load control system may include a load control device for providing power to an electrical load and a control device that may send instructions to the load control device for providing the power to the electrical load. The control device may communicate with the load control device using a link address assigned to the load control device. The load control device may provide power to the electrical load in a manner that causes the electrical load to indicate the link address assigned to the load control device. The link address may be identified by a user or a user device. The identified link address may be associated with a load control device identifier that may identify a physical location of a load control device that is assigned the link address. A user may control a load control device at a physical location by sending instructions via the link address.

Control-source devices may be associated with control-target devices of a load control system during a configuration procedure, such that the control-target devices are responsive to the associated control-source devices during normal operation. The configuration procedure may be executed using a network device having a visual display for associating the control-source devices and control-target devices. The control-source devices may be associated with the control-target devices on an area-by-area basis using an area configuration procedure. The control-target devices may be configured to flash a controlled lighting load according to a flashing profile during the configuration procedure. The flashing profile may be characterized by at least one abrupt transition between off and on, and at least one gradual transition between off and on, where the abrupt and gradual transitions are repeated on a periodic basis.

A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.
