Each Universal UPB Dimmer Transceiver Switch has one rocker/ button that controls a single load of up to 900W. Any faceplate option will control the local load 'out of the box' (factory default). UPB switches and modules are added to a UPB powerline network and configured using UPStart (PC based) software and Computer Interface Module (model UMC). By default the US2 is set to dim incandescent, halogen and magnetic low-voltage lighting. Dimming can be disabled for On/ Off control of fluorescent lights, fans, motors and other non-dimmable loads. The adjustable response time feature and fade rate function sets how quickly the output responds and dims lights on and off. The switch base accepts any one of the 13 faceplates. Any of the faceplate buttons or rockers can be configured to control the local load or lighting scene-links. Up to 250 UPB device and 250 scene- links can be used on a powerline network to control virtually anything connected to the household wiring.
