Product Overview

The CLW-DIMUEX-P is a Cameo® in-wall universal phase dimmer that controls the following load types: LED, incandescent, magnetic low voltage, and electronic low voltage. Its design matches the entire line of Cameo products, making it a great addition to new or retrofit installations.

Universal Phase Dimming
The CLW-DIMUEX-P features auto-load detection to automatically select the appropriate dimming method for the attached load. Auto-load detection allows for broad load type compatibility even if future changes to the load are made.

Integrated Keypad
Supporting up to four buttons, the CLW-DIMUEX-P is configurable for a variety of applications. Because the dimmer is attached to the Crestron® control network, it can function as a keypad to trigger remote actions.

Remote Dimmer
The CLW-DIMUEX-P supports dimming control of the same lights from more than one location. The CLW-SLVU-P remote dimmer connects to the traveler wire in a traditional three- or four-way circuit and dims the load attached to the CLW-DIMUEX-P.

Multigang Expansion
Devices may be installed side-by-side in a multigang electrical box with a compatible decorator faceplate (sold separately).

NOTE: Derating is required for multigang installations. Refer to the CLW-DIMUEX-P Quick Start at (Doc. 8482) for derating information.

infiNET EX Communications
infiNET EX wireless technology provides two-way RF communications throughout a residential or commercial structure without the need for physical control wiring. Each infiNET EX device acts as an expander by sending command signals to other infiNET EX devices in range (approximately 150 ft (46 m) indoors) to ensure reliability and stability.1

The CLW-DIMUEX communicates with a control system via a CEN-GWEXER or newer infiNET EX Wireless Gateway (sold separately). Up to 100 infiNET EX devices may coexist on a single wireless network.

Field-Replaceable Button Caps
The preinstalled rocker button cap (CLW-BTN-RKR) on the CLW-DIMUEX-P is field-replaceable with the included small (CLW-BTN-SM) and large (CLW-BTN-LG) button caps, allowing for engravable multi-button configurations.

Streamlined Installation
In addition to field-replaceable buttons, the CLW-DIMUEX-P features screwclamp connectors for simplified wiring that reduces installation time and material costs. The CLW-DIMUEX-P can be installed in standard gang boxes, making them the perfect choice for both new and retrofit projects.

  1. Any infiNET EX device that provides expander functionality will effectively extend the range of the wireless network beyond the initial range of the gateway. Battery-powered infiNET EX devices do not provide expander functionality. A dedicated infiNET EXWireless Expander, model CLW-EXPEX, is also available.
