Crestron CLCI-DIMUEX-W – In-Ceiling Wireless Dimmer, infiNET EX, 230VAC

Product Overview

The Crestron CLCI-DIMUEX-W is a wireless in-ceiling dimmer module that operates at 230VAC and communicates via the infiNET EX encrypted mesh wireless protocol. It installs directly into a standard back box above the ceiling plane, eliminating the need for Cresnet wiring to the dimmer location while maintaining full Crestron control. AV integrators and lighting control programmers use this module to add wireless dimming to lighting circuits in rooms where new low-voltage wiring is impractical.

Product Description

The CLCI-DIMUEX-W connects to the load-side mains wiring at the luminaire or junction box and controls the brightness of compatible dimmable 230VAC loads including forward-phase (leading-edge) and reverse-phase (trailing-edge) dimmers depending on the specific module variant. The infiNET EX wireless link connects to any Crestron infiNET EX gateway, placing this dimmer into the Crestron programming environment for scene control, occupancy-based dimming, and daylight harvesting integration. The module is designed for concealed in-ceiling installation, making it invisible from the occupied space once installed.

Key Features

• In-ceiling installation — mounts inside ceiling cavity at junction box, invisible from the occupied space
• infiNET EX wireless — encrypted 2.4 GHz mesh, two-way communication with Crestron processors and gateways
• 230VAC operation — designed for international and European mains voltage installations
• No Cresnet wiring required — wireless installation reduces cabling cost in retrofit and new-build projects
• Two-way feedback — actual load state reported back to Crestron for programming and diagnostics
• Compatible with Crestron lighting scenes — integrates into programmed lighting presets and occupancy control
• Compact form factor — fits standard European back boxes for concealed installation

Typical Applications

• Retrofit lighting control in existing buildings where running new Cresnet wiring is not feasible
• Conference rooms and breakout spaces requiring dimming without wall panel low-voltage wiring
• Hospitality guest rooms with Crestron scene-based lighting control over wireless infrastructure
• Open-plan offices where ceiling-mounted luminaires require centralized dim control from a Crestron processor
• 230VAC installations in international projects using Crestron infiNET EX wireless networks

FAQs

Does the CLCI-DIMUEX-W require a separate Crestron infiNET EX gateway?

Yes. The module communicates over infiNET EX wireless and requires a Crestron processor or gateway with infiNET EX capability, such as a 4-Series controller or a CENI-GWEXER module, to be present on the network.

What types of 230VAC loads can this dimmer control?

Refer to the Crestron product datasheet for the specific dimmer version to confirm compatible load types (forward-phase, reverse-phase, or universal). Using an incompatible load type can result in flickering, noise, or device damage.

Can this module be used in 120VAC North American installations?

No. The CLCI-DIMUEX-W is a 230VAC module intended for international installations. For North American 120VAC applications, Crestron offers separate in-ceiling dimmer models rated for 120VAC.
