Controls Two Separate Circuits

Simply Automated's SimplyBrilliant Universal UPB Dual Dimmer Controller Base (model US22-40) provides ultra-reliable control and energy saving timed-off control of new and existing lighting fixtures, lamps, fans and other electrical devices, including LED fixtures. Each unit has two dimmers that control two separate loads of 1W min. to 550W max. each. It can also transmit and receive lighting scene commands with other Universal Powerline Bus (UPB) switches, plug-in modules, fixture modules as well as any PC, security, home automation controller that provides a UPB serial driver option – to control virtually anything that connects to AC power anywhere in the home.

The model US22 is the ideal solution to reduce the number of switches and j-boxes in the home. The dual load output works well in paddle fan and bathroom light and fan applications. The response time function is adjustable down to 300mSec so lights come on quickly. The energy saving timer function automatically turns off the switch load after a pre-set period of 1, 5 or 30 seconds, 1, 2, 4, 10, 20, 30, 40, or 50 minutes, 1, 2, 3, or 4 hours. The timer can be disabled so the US22 functions like a standard dimmer (no timer function) or enabled to activate with a rocker push. In addition, another button or rocker on the US22 (or another UPB switch) can command any of the timer functions of the US22, via a lighting scene-link command, to enable any selection of timed off options (e.g. buttons for 1 minute, 4 minutes, 10 minutes, 1 hour).
