Control4® Square Dual Load Wireless Adaptive Phase Dimmer

The Control4® Square Dual Load Wireless Adaptive Phase Dimmer combines elegant dimming with a configurable keypad for the
ultimate in lighting control of up to two lighting loads. Unlock the power of one-touch automation by simply replacing an existing light
switch with a wireless dimmer.



Provides independent dimming control of up to two lighting circuits.
• Turns a standard light switch or dimmer into a fully customizable keypad and dimmer.
• Wireless communication and standard wiring provide easy installation in new construction and retrofit environments.
• Compatible with a variety of load types including LEDs, incandescent, halogen, electronic low-voltage (solid state)
transformers, magnetic (iron core) low-voltage transformers, fluorescents, compact fluorescents.
• Supports both forward-phase (leading edge) and reverse-phase (trailing edge) dimming.
• Automatically detects load type and determines the appropriate dimming type.
• Protection circuitry prevents device damage in case of short circuit or excessive load.
• Continuously measures energy being used by the attached load.
• Configure with two to seven buttons using five different button sizes for a total of 38 possible configurations.
• Easy reconfiguration means there's no need to worry about how many buttons will be needed on a specific dimmer before (or even
after) installation.
• Elegant, sophisticated design makes a beautiful addition to any home or business.
• Custom engraving available to clearly identify each button.
• Backlit button engraving with programmable color control for easy readability regardless of time of day or light level.
• Programmable RGB LEDs provide status feedback for lighting and other devices in the system.
• Ambient light sensor can automatically adjust backlight and status LED brightness depending on the light level in the room.
• Ships as "neutral" device with no buttons included. Keypad-style button kit and rocker-style button kits sold separately in a variety
of colors (see "Available accessories").
• Control4® screw-less faceplates, sold separately, provide a sleek profile (see "Available accessories").
• Installs in standard square (UK/China-style) single-gang wall box.
• Not compatible with round (EU-style) or UK-style double-gang wall boxes.

Model numberC4-SDAPD240-N
Power requirements230VAC +/-10%, 50/60 Hz
This device can function with or without a neutral AC connection
depending on load type. Wiring with a neutral is always the
preferred wiring method (if possible).
When wired without a neutral:
• Load 1 will be forced into a switch-only mode. It will not be
possible to dim load 1.
• The minimum wattage requirements increase. See "minimum load"
section below.

^{1} Important! When dimming magnetic (MLV) loads, each transformer must be loaded to at least 50% of its maximum load.
^{2} Incandescent and mains-voltage halogens should be dimmed using reverse phase. If forward-phase dimming is forced
with either of these load types and the dimmer is wired without a neutral, load 2 must be derated to 150W.
^{3} The minimum and maximum load requirements for fluorescent, CFL, and LED loads can vary greatly, depending
upon the specific fixture and/or bulb being used. The quality and performance of these load types varies greatly from
manufacturer to manufacturer. At higher wattages, in-rush current spikes may cause an overcurrent fault on the dimmer.
At low wattages, particularly when the dimmer is wired without a neutral, the light may not be able to completely turn
off, may flicker, or may cause the dimmer to power starve. Control4 strongly recommends bench testing the actual loads
being used in the exact wiring configuration that will be used before performing the installation.
