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.

Important Note: Faceplates and buttons (color change kits) are not included. Don’t forget to order faceplates and color change kits separately.



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.
