Crestron CM2-DIMUEX-RKR Cameo 2 In-Wall Universal Phase Dimmer with infiNET EX Wireless Communication, 100-240VAC, Rocker Only

About the Crestron CM2-DIMUEX-RKR

Auto-load detection selects the appropriate dimming method, reverse phase or forward phase, for the attached load, which keeps the dimmer compatible even if the load type changes in the future. It is rated for incandescent, tungsten halogen and magnetic loads up to 600 W/VA at 120-240VAC (500 W/VA at 100VAC) and motors up to 1/8 HP, and has over current protection.

RKR models accept only a large rocker button, and one is included. Button events are programmable for normal, tap, double-tap and press and hold. A full RGB backlit bargraph, which can also act as three RGB indicator regions, and three RGB backlit text regions give feedback. The white of the backlight adjusts between 2000K and 8000K, and an ambient light sensor provides day and night modes.

The dimmer talks to the system over infiNET EX 2-way RF at 2.4 GHz and needs a CEN-GW1, CENI-GW1, MC4, MC4-R, CEN-GWEXER or CENI-GWEXER gateway, sold separately. CM2-AUX and CM2-KPEX multiway controllers can be added over a traveller wire. It fits a 1- to 4-gang wall box of the type Crestron specifies, with an 89 mm box depth recommended and derating required in multi-gang applications.

Questions about the Crestron CM2-DIMUEX-RKR

What is the Crestron CM2-DIMUEX-RKR?

It is the rocker only version of the Cameo 2 in-wall universal phase dimmer, with infiNET EX wireless communication and 100-240VAC line power. It dims LED, incandescent, magnetic low voltage and electronic low voltage loads, using auto-load detection to choose reverse or forward phase.

How does the CM2-DIMUEX-RKR differ from the full keypad CM2-DIMUEX?

RKR models accept only a large rocker button, while full keypad models take two to six buttons. On the rocker version, feedback comes from three RGB backlit text regions and a full RGB backlit bargraph that can also work as three RGB indicator regions.

What are the load ratings of the CM2-DIMUEX-RKR?

Incandescent, tungsten halogen and magnetic loads are rated at 500 W/VA at 100VAC or 600 W/VA at 120-240VAC, and motors at 1/8 HP. With a neutral connected there is no minimum load; without one, the minimum is 5 W incandescent or 2 LED bulbs.

What is the difference between the CM2-DIMUEX-RKR-W-S and CM2-DIMUEX-RKR ENGRAVED?

Both are the rocker only universal phase dimmer. The CM2-DIMUEX-RKR-W-S is the standard engraved version in White Smooth. The CM2-DIMUEX-RKR ENGRAVED is custom engraved, with its finish specified in the custom engravings file.

Which gateway does the dimmer need?

It needs a Crestron wireless gateway, sold separately: the CEN-GW1 or CENI-GW1, the MC4 or MC4-R, or the CEN-GWEXER or CENI-GWEXER. Typical infiNET EX range is 46 m (150 ft) indoors and 76 m (250 ft) outdoors to the nearest mesh network device, subject to site conditions.

How much is the Crestron CM2-DIMUEX-RKR?

Crestron asks its dealers to give the price of the CM2-DIMUEX-RKR 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 CM2-DIMUEX-RKR?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CM2-DIMUEX-RKR 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 CM2-DIMUEX-RKR come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CM2-DIMUEX-RKR 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 CM2-DIMUEX-RKR 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 CM2-DIMUEX-RKR 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.
