The US1W9 is a pre-configured version of the US11-40.
The SimplyBrilliant UPB Dimming Transceiver Switch, model US11-40, provides direct load control and or remote control of permanently-installed new or existing lighting fixtures, lamps and other electrical devices connected to UPB devices. Each unit has one rocker switch that directly controls a load up to 900W (see Table 1). Incandescent lamps can be turned ON or OFF, and can also be dimmed and brightened. The US11-40 can be configured to turn other types of non-dimmable loads ON and OFF.
The timer function can be used to automatically turn OFF loads, after a preset time, like bathroom fans or heat lamps. The switch may also act as a transmitter or receiver that can communicate with other UPB devices, either individually or collectively for lighting scenes.
Note: This incandescent dimmer cannot be used to dim fluorescent, electronic low-voltage or metal halide lighting, unless specifically allowed by the lighting manufacturer. Please see instructions to configure this product for ON/OFF operation with these types of lighting.
Note: With the SimplySmart pre-configured devices, each device has been hard coded with a unique ID, which means you'll only want one of each of the following in a single home: DKIT-02, DKIT-02, UML7, UML8, US1W9, US1W10, US2TP11, or US2W12. Having more than one of these in the home will make communication unstable, as these are designed to be starter devices only.
