* NOTES:
- The maximum load requirements for fluorescent, CFL and LED loads can vary greatly depending upon the specific fixture and/or bulb being used. These load types have significant in-rush current which can trip the protection circuitry on the device.
- The quality and performance of these load types vary greatly from manufacturer to manufacturer. When using these load types, we recommend testing in advance. If problems are found, simply changing ta different bulb manufacturers may solve the problem.
- Additionally, we do not recommend the use of fluorescent, CFL, or LED loads without a neutral wire connected to the dimmer due to the capacitive nature of these load types.
- Wiring with a neutral is always the preferred wiring method (if possible).

Further, Control4 is NOT liable for any damage incurred with the misuse of this product. See “Troubleshooting.” IMPORTANT! Do NOT use a power screwdriver to install this device. If you do, you may overtighten the screws and strip them. Also, overtightening the screws may interfere with proper button operation. IMPORTANT! This is an electronic device with intricate components.Handle and install with care! IMPORTANT! Control4 does not guarantee the performance of any bulb or lamp/fixture in your environment. CUSTOMER ASSUMES ALL RISKS, INCLUDING ANY DAMAGE TO CONTROL4 PRODUCTS, ASSOCIATED WITH (i) THE TYPE, LOAD RATING AND QUALITY OF THE BULB AND LAMP/FIXTURE, OR (ii) ANY USE OR INSTALLATION NOT IN ACCORDANCE WITH THE DOCUMENTATION FURNISHED BY CONTROL4, EITHER WITH THE CONTROL4 PRODUCT OR AT WWW.CONTROL4.COM. IMPORTANT! When used in conjunction with an Auxiliary Keypad (C4-KA-xx), the wire connecting the Auxiliary Keypad to the dimmer must not exceed 45 m (150 ft.) at 120V AC and 30 m (100 ft.) at 277V AC.
Installation instructions
- Ensure that the location and intended use meet the following criteria:• Do not exceed the load capacity requirements of the dimmer. In multi-gang installations, a reduction of the dimmers’ capacity is required to allow the dimmers to be installed side-by-side. Refer to the load ratings in the specifications above for details.• Install in accordance with all national and local electrical codes.• The range and performance of the wireless control system is highly dependent on the following: (1) distance between devices; (2) layout of the home; (3) walls separating devices; and (4) electrical equipment located near devices.
- If installing in a multi-gang scenario, use pliers to remove the inner-side breakaway tabs. Bend each tab forward first, and then back and forth until it breaks off. Remove the inner-side tabs ONLY on any device side that will be adjacent to another device. DO NOT remove tabs on any side that will become the outer side of a group of devices. Handle the device with care after removing the tabs, as the broken edge can be sharp.
- Turn off the local electrical power by either switching off the circuit breaker or removing the fuse from the fuse box. To ensure the wires do NOT have power running to them, use an inductive voltage detector.NOTE: The backbox wiring shown in this document is an example. Your wire colors and functions may differ. If you are not sure which wires are the LIne In/Hot, Neutral, Load, Traveler, and Earth Ground wires, have a trained electrician perform the installation.
- Prepare each wire. Wire insulation should be stripped back 5/8 of an inch from the wire end (see Figure 1).Figure 1. Strip wire insulation
- Identify your wiring application and then see the appropriate wiring diagram in the “Sample Wiring Configurations” section below. IMPORTANT! Not grounding this product, as described in the “Warnings and Considerations” section, may result in an installation less immune to damage caused by electrical disturbances, such as ESD or lightning, and may void the warranty.
- Identify and connect the dimmer wires to the backbox wires using the wire nuts. IMPORTANT! The yellow wire is not a traditional traveler. It cannot directly power a lighting load. It must be used only to connect to a Control4 Auxiliary Keypad. See “Sample Wiring Configurations.” TIP: If you are using a Control4 push-on (screwless) faceplate in a multi-gang installation, attach the black faceplate subplate to all of the devices that will be installed into the backbox prior to attaching the devices to the backbox. This will help ensure that all the devices are properly aligned and on the same plane after installation.
- Fit the wires back into the backbox. Bend the wires in a zigzag pattern so that they easily fold into the backbox (Figure 2).Figure 2. Bend the wires
- Align the dimmer to the backbox (the load rating label should be at the bottom) and fasten it with screws. Tighten the screws until the backside of the yoke plate is even with the wall surface, but no further. Overtightening can warp the dimmer and cause mechanical malfunction.
- Install the Control4 Faceplate following the instructions in the Faceplate Installation Guide or attach a standard Decora-style faceplate.
- Attach the buttons, actuator bar, and sensor bar as described in the Keypad Button Installation Guide.
- Turn on power at the circuit breaker or replace the fuse from the fuse box.
TIP: If you are using a Control4 push-on (screwless) faceplate in a multi-gang installation, attach the black faceplate subplate to all of the devices that will be installed into the backbox prior to attaching the devices to the backbox. This will help ensure that all the devices are properly aligned and on the same plane after installation.
NOTE: If the light flickers, adjust the dimmer’s max/in settings in Composer (for example, min 15%, max 85%). See ctrl4.co/ dimmer settings.
Operation and configuration
On initial power-up, all status LEDs on the dimmer will illuminate green indicating that the device has power. To set up this dimmer for use with a Control4 system, refer to the Composer Pro User Guide.To operate this dimmer as a stand-alone device prior to configuration in Composer Pro:
- If the light is off, click any button to turn the light on.
- If the light is on, click any button to turn the light off.
- Press and hold any button to ramp the light up/down. Release the button at the desired light level.
- If they split up/down buttons have been installed in the bottom button slot, the up and down arrows will ramp and fade the light respectively.
Air gap switchDuring routine lamp replacement, you should remove power from the lamp by engaging the air gap mechanism.
- To engage, press on the right side of the top actuator bar until the left side pops out. All LEDs on the dimmer will turn off and the dimmer will no longer control the light when the air gap mechanism has been engaged.
- To return power to the dimmer and lamp, press on the left side of the top actuator bar until it snaps back into place.Figure 3. Dimmer with actuator bar
