    Full text manual (for reference)

    Full Specifications for the SimplyBrilliant® US11-40-W (SAUS1140W) — a Standard UPB Dimmer-Controller Switch, single rocker with white faceplate and configurable countdown timer, communicating over existing home power lines via Universal Powerline Bus (UPB) technology.

    Overview

    The US11-40-W is a Standard UPB Dimmer-Controller Switch Base (model US1-40) with a gloss white faceplate (model ZS11-W) and countdown timer feature. Color options for the single rocker faceplate (ZS11 Series, sold separately) include almond, light-almond, ivory, black, or brown — faceplates are easily changed in the home. The US11-40-W provides ultra-reliable control and timed-off control of new and existing lighting fixtures, lamps, fans, and other electrical devices. Each unit has one switch that controls a load of 1 Watt minimum to 900 Watts maximum, and can transmit/receive lighting scene commands and status with other UPB switches, plug-in modules, fixture modules, and any PC/security/home automation controller with a UPB serial driver.

    Timer Function

    The timer automatically turns off the switch load after a preset period of 1, 5, or 30 seconds; 1, 2, 4, 10, 20, 30, 40, or 50 minutes; or 1, 2, 3, or 4 hours. The timer can be disabled so the US11 functions as a standard single-rocker switch, or enabled to activate with a rocker push (e.g., single push turns on with timer, double push turns on without timer, or vice versa). A UPB switch such as the model US2-40 Universal Dimmer-Controller can command any of the US11's timer functions via lighting scene-links, enabling any selection of timed-off options (e.g., buttons for 1 minute, 4 minutes, 10 minutes, 1 hour).

    Fade rates are also configurable (snap, 0.8, 1.6, 3.3, 5, 6.6, 10, 20, 30 seconds, or 1, 2, 5, 10, 15, 30 minutes), and the rocker can control both the local load and a lighting scene separately — e.g., press and hold to dim up/down, single tap to fade to 100%/0%, and double tap to send a scene link with or without affecting the local load.

    Advantages & Features

    • No new wires — communicates over existing power lines; transmits and receives UPB lighting scenes.
    • UPB technology delivers exceptional reliability, noise immunity, low installed cost vs. hardwired/RF solutions, and no interference between adjacent homes.
    • Easily configured or reconfigured with UPStart (PC) software, including an UPStart Wizard for first-time users.
    • Configurable output: dimming or on/off with dimming disabled; 900 watts / 7.5 amps max, 1 watt min; supports incandescent, halogen, fluorescent, LED, low-voltage transformers, ballasts, and motors/pumps/fans.
    • True rocker action: press and hold for 200 dimming steps and Resume Dim; single tap fades up/down; double tap snaps to 100%/0%; adjustable (faster) response time and fade rate.
    • Interchangeable rocker assemblies: change color in the field for higher flexibility and lower inventory costs.
    • Aesthetically pleasing blue/green LED indication.
    • Patented contoured heat sink for cooler operation.
    • Thermal overload protection for added safety.
    • Dedicated Remote Switch (Model USR) connection provides an inexpensive 3-or-more-way control option.
    • Rocker colors (sold separately, ZS11 Series): white, almond, light almond, ivory, black, or brown.

    Applications

    The single rocker dimming-controller is used wherever multi-rocker or multi-button switches will never be required. The adjustable response time allows these switches to turn on quickly, and light level status can be automatically transmitted whenever the rocker is pushed. These switches can be used as 'virtual' 3-way (or more-way) switches when no traveler wires are available — a traveler wire connection provides 3-or-more-way functionality when the US11 is connected to a remote switch (model USR) only.

    Bathroom fan and circulating hot water pump control are the most common timer applications: the single rocker can be configured to turn a fan/light on with timed-off at a single push, and a double push turns it on without the timed-off feature (or vice versa). Both single and double push functions can utilize scene links and the timer option — for example, a single tap turns on the local load while a double tap sends a scene link without affecting the local load. An adjacent (or remote) multi-button switch such as the US2-40 with a ZS25O faceplate can control the US11's timed-off feature this way, with labels (model ZLK-01) helping users select different off times (4 min, 10 min, 1 hr). Other uses include heat lamps, outdoor exit lighting, or relays/inputs requiring momentary AC control signals. The US11 is an excellent energy-saving solution for areas where lights are frequently left on (bath/laundry rooms, closets, garages, etc.).
