The Domus CHAM-TOUCH-3C is a glass touch wall control forRGBW LED strip dimming, colour, colour-change speed and scene memory working over RF and Bluetooth at 2.4GHz.1207529.1mm.

The wall cutout is 70 44 20mm, and it is on thedatasheet and in no product field.

The plate is 12075mm and sits over the aperture; the20mm depth is what has to exist behind the wall. In plasterboard with a standardmounting block that is usually fine; in masonry or behind tiling it needs planning.

Two dimension oddities on this record. It holds awidth of 90mm where the single-colour version of the same plate holds 80mm though both share one datasheet and one plate size. And it holds a“diameter” of 29.1mm, which is not a diameter at all: it isthe plate’s depth, from the datasheet, stored in the wrong field. A rectangular glassplate has no diameter.

Work to 1207529.1mm and the 70 44 20mm cutout, and we will confirm before your electrician cuts.

What the RGBW version adds

• Dimming, as the single-colour plate does.
• Colour selection across the RGBW range.
• Colour-change speed it runs a changing-colour mode and lets you speed it upor slow it down from the wall, which a plain colour picker does not.
• Scene memory the feature people actually use. A warm static colour forevenings and a set white for working, each a single touch away.
• Its colour-changing flag is correctly set worth saying, because thesingle-colour version of this same plate carries the same flag and cannot use it.

RGBW rather than RGB the distinction that matters

• RGB makes white by mixing red, green and blue, which gives a visible colour cast.
• RGBW adds a fourth channel with a dedicated white LED, so white is actuallywhite.
• Most colour installations spend most of their life on white a cove that isred at Christmas and warm white the rest of the year. If that describes yours, the strip should beRGBW, and this plate handles it.
• The plate has to match the strip. An RGBW plate on an RGB strip leaves a channelunused; an RGB strip on a single-colour plate does not work at all.

It does nothing on its own

• It transmits to the CHAM-BT-RF-5C receiver, which sits between your driver and yourstrip and does the actual work.
• The receiver is listed in this catalogue as the “Bluetooth RF 5-1 UniversalController” a name containing neither “CHAM” nor “receiver”, which is why nothing oneither page connects them.
• A full installation is four things: a constant-voltage driver, the receiver, the RGBWstrip, and this plate.
• Tell us the strip and we will specify the chain.

Wall plate, handset, or both

• The plate is where people look for a control, and it needs no app or paireddevice.
• It runs on 240V mains no battery, unlike the CHAM-REM handsets.
• Both can coexist: the plate for everyday use, the CHAM-REM-3C handset for the sofa,and Bluetooth from a phone for setting scenes.
• How many scenes it stores, and whether they survive a power cut, is not recorded.Ask us.

The rest of the specification

• White glass face. 2.4GHz transmission.
• Operating temperature 040C, consumption <15mA,operating voltage 240V.
• Mains-wired licensed electrical installation.
• 2.4GHz is a crowded band. In a dense building, keep the receiver away from therouter where you can.

Where it works

• RGB and RGBW strip installations using the CHAM-BT-RF-5C receiver.
• Living rooms, bars, media rooms where colour is part of the room.
• Alongside a CHAM-REM-3C handset and the phone app.
• Not for a single-colour strip use the CHAM-TOUCH-1C.
• Not usable without the receiver.
• Confirm the wall cutout before your electrician cuts.

Specifying it

RF + Bluetooth glass touch wall control, RGBW.Plate 1207529.1mm. White glass. Wall cutout 704420mm datasheet only.Transmission 2.4GHz. Dimming, colour, colour-change speed and scene memory.Operating temperature 040C, consumption<15mA, operating voltage 240V.

Requires the CHAM-BT-RF-5C receiver, sold separately. Its recorded “diameter” of 29.1mm is the plate’s depth in the wrong field, and itsrecorded width differs from the identical single-colour plate’s. Work to the datasheet.Licensed electrical installation. Warranty 3 years.

Questions

What size cutout does the wall need?

70 44 20mm, from the datasheet, and it appears in no product field. The plate is 120 75mm and sits over the aperture; the 20mm depth is what has to exist behind the wall. In plasterboard with a standard mounting block that is usually fine; in masonry or behind tiling it needs planning before the tiler arrives, not after.

Why does the record show a “diameter”?

Because 29.1mm has been put in the wrong field it is the plate’s depth from the datasheet, not a diameter. A rectangular glass plate does not have one. Work to 120 75 29.1mm, and note the recorded width also differs from the identical single-colour plate’s, which is another reason to use the datasheet figures.

What is the difference between RGB and RGBW?

A dedicated white channel. RGB makes white by mixing red, green and blue, which gives a visible colour cast; RGBW adds a fourth channel with a proper white LED. Most colour installations spend most of their life on white a cove that is red at Christmas and warm white the rest of the year so if that describes yours, the strip should be RGBW and this plate handles it.

Will it work on its own?

No. It transmits to the CHAM-BT-RF-5C receiver, which sits between your driver and your strip and does the actual work. The receiver is sold separately and listed here as the “Bluetooth RF 5-1 Universal Controller”. A full installation is four things: a constant-voltage driver, the receiver, the RGBW strip and this plate. Tell us the strip and we will specify the chain.

What does the colour-change speed control do?

It runs a changing-colour mode and lets you speed it up or slow it down from the wall, which a plain colour picker does not. In practice most people set a slow drift for a bar or a media room and leave it, but being able to adjust the rate from the plate rather than an app is the difference between using it and not.

Can I use a remote as well?

Yes, and it is a sensible combination the plate for everyday use where people look for a control, the CHAM-REM-3C handset for the sofa, and Bluetooth from a phone for setting scenes. All three talk to the same receiver. The plate also runs on mains, so there is no battery to replace.

How many scenes can it store?

Not recorded, and neither is whether they survive a power cut. Ask us and we will get both from Domus on a colour installation the scenes are most of the value, so it is worth knowing before you commit.
