Description
The Onset Two-Wire, Low-Voltage Dimmer is a digital, micro-touch preset dimmer, designed
for use with low-voltage (600VA-1000VA) incandescent, magnetic low-voltage, neon, and
cold cathode. The unit is equipped with an automatic fade and LED readout, providing fullfunction, three-way and multi-location dimming control when used with Onset Remotes.
Onset Masters and Master Remotes have the ability to control up to four Onset dimmers
simultaneously, offering an economical way to create preset lighting scenes.
Features
• Installation requires only two wires. A neutral connection is not required.
• LED readouts, including:
- A soft green LED which indicates the current preset
- A bright green LED which indicates the current level
- A blinking red LED which indicates a fading off process
- A glowing red LED which indicates that the dimmer is off
• As an individual device, the Onset Two-Wire, Low-Voltage Dimmer has the capability
to recall two presets—a user-selected “on” level and full brightness.
• Manual override—allows the lights to be adjusted to any level without affecting the
preset level(s), including full brightness.
• Automatic fade—gently turns the lights on and off, thereby preserving the unit’s lamp life.
• Power failure memory—a feature that returns the dimmer to the level of lighting the unit
held before the power failure occurred.
• Full-Function, Onset Remotes allow total dimming control from multiple locations.

The Onset Two-Wire, Low-Voltage Dimmer is UL Listed to U.S. and Canadian safety standards
for 120VAC, 60Hz, 600VA/1000VA operations to control magnetic low-voltage, neon, cold
cathode, quartz halogen and incandescent lighting loads. Only two wires are required for
installation. (Neutral connection not required.) Device operations include:
• Fade to preset
• Fade to full brightness
• Fade to off
The unit has the capability of storing two presets in its memory—a user-selected preset and
full brightness. Through the use of an Onset Master controller, it is possible to control up to
four devices simultaneously, and to recall two preset scenes. This dimmer also allows manual
override of any preset level, without affecting the level set into memory.
The Onset Two-Wire, Low-Voltage Dimmer has LEDs that indicate the preset lighting level,
the user preset and the off status. Following a power interruption, the Onset Two-Wire,
Low-Voltage Dimmer returns to the lighting level it maintained before the interruption. It also
accepts full-function commands from an unlimited number of multi-location Onset Remotes.
The unit’s toroidal filters are used to suppress RFI and EMI. Its air gap is used to open the
circuit completely. However, the air gap is unobtrusive and is not required for normal
operations.
This device mounts in a single-gang wall box and can be combined with a designer-style
faceplate, as well as Compli® Screwless Faceplates which come in the colors of white, ivory,
grey, almond or black. (sold separately)
