About the Crestron CLWI-DIMUEX

Universal dimming gives the CLWI-DIMUEX automatic compatibility with both forward and reverse phase loads. The dimmer also supports any third party maintained or momentary switch for remote dimming, so the light can be dimmed from that switch as well as from the dimmer itself. A bargraph LED array gives real-time status feedback.

Connected to the Crestron system, the dimmer also works as a keypad with up to six buttons, sending commands that trigger whole-room lighting scenes or distributed audio functions. It communicates using infiNET EX two-way RF wireless technology on a 2.4 GHz mesh network, in which every device acts as an expander. No physical control wiring is needed, so it can go in almost any location in a home or commercial building.

The engravable buttons can be swapped in the field with tool-free snap-on fittings, so the layout can change with the room's décor or use. The dimmer has screw-clamp connectors. This page covers the white (CLWI-DIMUEX-W) and anthracite (CLWI-DIMUEX-ANTH) versions. Crestron's Lighting Fixture Compatibility page shows which Crestron lighting devices have been tested with third party lighting fixtures.

Questions about the Crestron CLWI-DIMUEX

What is the Crestron CLWI-DIMUEX?

It is a universal phase in-wall dimmer for 230 Volt applications. It gives Crestron dimming control of lighting in new or retrofit projects, communicates over infiNET EX wireless, and can also work as a keypad with up to six buttons for lighting scenes or distributed audio functions.

Does the CLWI-DIMUEX work with forward and reverse phase loads?

Yes. It is a universal phase dimmer, which provides automatic compatibility with both forward and reverse phase loads. For specific fittings, Crestron's Lighting Fixture Compatibility page shows which Crestron lighting devices have been tested and are compatible with third party lighting fixtures.

Can a remote switch be used with the CLWI-DIMUEX?

Yes. The dimmer supports any third party maintained or momentary switch for remote dimming, so the light can also be dimmed from that switch. The dimmer itself connects to the Crestron system wirelessly over infiNET EX, so it needs no physical control wiring to the control system.

What is the difference between the CLWI-DIMUEX-W and CLWI-DIMUEX-ANTH?

Both are the Universal Phase In-Wall Dimmer, 230VAC. The CLWI-DIMUEX-W has a white finish and the CLWI-DIMUEX-ANTH has an anthracite finish. When replacing a dimmer, check the part number on the existing unit so that the new one matches the rest of the room.

Can the buttons be customised?

Yes. The buttons are engravable and field-replaceable, and they attach with positive snap-on fittings that need no tools. The dimmer can be configured for up to six buttons, so the layout and engraving can be changed after the dimmer is in place if the room's décor or use changes.

How much is the Crestron CLWI-DIMUEX?

Crestron asks its dealers to give the price of the CLWI-DIMUEX directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.

Can 1Install supply, install and programme the CLWI-DIMUEX?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CLWI-DIMUEX on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.

Does the CLWI-DIMUEX come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CLWI-DIMUEX develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.

Is the CLWI-DIMUEX in stock?

We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Can I buy the CLWI-DIMUEX without installation?

Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
