About the Crestron CLWI-DIMUNEX
Universal dimming gives automatic compatibility with both forward and reverse phase loads, and the dimmer is designed for low-wattage loads, especially LEDs. It can also act as a keypad: once connected to the Crestron network, its buttons can trigger whole-room lighting scenes or distributed audio functions. It can be configured for up to six buttons, and a bargraph LED array gives real-time status feedback.
Communication is over infiNET EX two-way RF wireless on a 2.4 GHz mesh network, so no physical control wiring is needed. The dimmer links to the control system through an infiNET EX wireless gateway: the CEN-GWEXER, DIN-AP3MEX or MC3. Up to 100 infiNET EX devices can share one wireless network, and each non-battery-powered device added increases the range and stability of the whole network.
The buttons are field-replaceable and engravable, with positive snap-on fittings that need no tools, so the layout can be updated if the room changes. The dimmer has screw-clamp connectors. This page covers the white (CLWI-DIMUNEX-W) and anthracite (CLWI-DIMUNEX-ANTH) versions. Crestron's Lighting Fixture Compatibility page lists which Crestron lighting devices have been tested and are compatible with third party lighting fixtures.

Questions about the Crestron CLWI-DIMUNEX
What is the Crestron CLWI-DIMUNEX?
It is a universal phase in-wall dimmer with neutral wire for 230 VAC applications, designed for low-wattage loads, especially LEDs. It communicates over infiNET EX wireless and can also be used as a keypad with up to six buttons for lighting scenes or distributed audio functions.
What loads is the CLWI-DIMUNEX designed for?
Crestron designed it for low-wattage loads, especially LEDs. Universal dimming provides automatic compatibility with both forward and reverse phase loads. To confirm a specific fitting, Crestron's Lighting Fixture Compatibility page shows which Crestron lighting devices have been tested and are compatible with third party lighting fixtures.
Which gateway does the CLWI-DIMUNEX need?
It communicates with the Crestron control system through an infiNET EX wireless gateway, model CEN-GWEXER, DIN-AP3MEX or MC3. Up to 100 infiNET EX devices can coexist on one wireless network, and every non-battery-powered device added increases the range and stability of the network.
Can the buttons be changed later?
Yes. The buttons are field-replaceable and engravable, and they fit 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 updated if the décor or use of the room changes.
Which finishes are available?
This page covers two finishes of the same dimmer: CLWI-DIMUNEX-W in white and CLWI-DIMUNEX-ANTH in anthracite. Both are the Universal Phase In-Wall Dimmer with Neutral Wire, 230 VAC. When replacing a unit, check the part number on the existing dimmer so that the finish matches.
How much is the Crestron CLWI-DIMUNEX?
Crestron asks its dealers to give the price of the CLWI-DIMUNEX 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-DIMUNEX?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CLWI-DIMUNEX 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-DIMUNEX come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CLWI-DIMUNEX 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-DIMUNEX 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-DIMUNEX 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.
