Abstract: A building control device comprising a wireless interface and a controller configured to monitor when the wireless interface becomes disconnected from the network. When the wireless interface becomes disconnected from the network, the controller may attempt to reconnect the wireless interface to the network and if successful, return to monitoring for when the wireless interface becomes disconnected from the network. If not successful, the controller may switch the wireless interface into a configuration mode to establish a direct wireless connection with a remote device, receive updated network credentials from the remote device while in the configuration mode, exit the configuration mode, and connect the wireless interface to the network or another network using the updated network credentials.

Abstract: Devices, methods, and systems for disinfecting air and surfaces are described herein. The systems may include a source of light, a reflector, a motor, and a controller. The source of light may provide ultraviolet germicidal irradiation light and the light may be selectively provided. The reflector may extend along and/or around the source of light. The motor may be coupled to the reflector and cause the reflector to adjust relative to the source of light so as to direct light at different target locations. The controller may determine occupancy in a room in which the system is located. When the room is not occupied, the controller may cause the reflector to be adjusted to an unoccupied position. When the room is occupied, the controller may cause the reflector to be adjusted to an occupied position.
