The Domus CHAM-REM-3C is a handheld RF and Bluetooth remote forRGBW LED strip dimming, colour, colour-change speed and scene memory witha magnetic back and a mounting bracket.1604020mm.

On its own, this remote does nothing. It transmits to theCHAM-BT-RF-5C receiver, which sits between your driver and your LED strip and does theactual 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 colour installation needs four things: a constant-voltagedriver, the receiver, the RGBW strip, and this remote.

All three CHAM remotes share that one receiver, so the remote follows the striprather than the hardware.

What it controls

• Dimming across the whole range.
• Colour across RGBW.
• Colour-change speed it runs a changing-colour mode and lets you speed it upor slow it down. That is the control most colour installations actually need: the choice is rarely”which colour” and usually “how fast, and how subtle”.
• Scene memory a set colour and level saved to a single press.
• Its colour-changing flag is correctly recorded, unlike the single-colour remote andwall plate in the same family, which carry the same flag and cannot use it.

RGBW rather than RGB

• RGB makes white by mixing red, green and blue, which gives a colour cast.
• RGBW adds a dedicated white LED channel, so white is actually white.
• Most colour installations spend most of their time on white. If yours will, thestrip should be RGBW and this remote handles it.
• Match the remote to the strip. There is no benefit in an RGBW remote on asingle-colour strip, and the CHAM-REM-1C is the simpler answer there.

The magnet is a better detail than it sounds

• A magnet on the back holds the remote to the supplied bracket.
• A remote that has a place on the wall gets used; one that lives in a drawer does not and a colour installation only controllable by a lost handset ends up stuck on whatever it wasleft on, which on a colour strip is far more conspicuous than on a plain one.
• Mount the bracket where a light switch would be, so people find it where they expecta control.
• It still lifts off to be used from the sofa, which a fixed wall plate cannot do.
• If you want a permanent wall control as well, the CHAM-TOUCH-3C is the mains-wiredglass plate. The two coexist.

The three remotes in this family

Tell us the strip you are running and we will specify the matching remote and thereceiver.

What is not recorded

• Battery type. Its tunable-white sibling takes two AAA cells; we are not assuming thesame. Ask us.
• RF range. No figure in any source. In practice RF handsets of this kind work acrossa normal room and through a plasterboard wall but if the receiver will be a long way from whereyou sit, tell us.
• Scene count and whether scenes survive a power cut.
• Its datasheet did not yield readable figures, so everything here comes from therecord and Domus’s description.

Where it works

• RGB and RGBW strip installations using the CHAM-BT-RF-5C receiver.
• Media rooms, bars, coves and feature lighting anywhere the colour changes.
• Alongside the CHAM-TOUCH-3C wall plate and the phone app.
• Not for a single-colour strip use the CHAM-REM-1C.
• Not usable without the receiver.
• Ask us about the battery and the RF range before ordering.

Specifying it

Handheld RF + Bluetooth RGBW remote control dimming, colour, colour-change speed andscene memory. 1604020mm, with a magnetic back and a mountingbracket.

Requires the CHAM-BT-RF-5C receiver sold separately, listed as the”Bluetooth RF 5-1 Universal Controller”. The remote does nothing without it. Battery type, RF range and scene count are not recorded in any source ask us andwe will confirm. Figures here are from the product record and Domus’s description; the datasheet did notyield readable values. Warranty 3 years.

Questions

Will this work on its own?

No. It is a transmitter it needs the CHAM-BT-RF-5C receiver, which sits between your driver and your LED strip and does the actual work. The receiver is sold separately and listed in this catalogue as the “Bluetooth RF 5-1 Universal Controller”, a name containing neither “CHAM” nor “receiver”. A colour installation needs four things: a constant-voltage driver, the receiver, the RGBW strip and this remote.

Which of the three remotes do I need?

Follow the strip. Single colour: the 1C. Tunable white: the 2C, which also handles two zones. RGB or RGBW: this 3C. All three work with the same receiver, so the receiver choice does not constrain you. Tell us what strip you are running and we will specify the matching remote.

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 time on white, so if yours will, the strip should be RGBW and this remote handles it either way.

What does the colour-change speed control do?

It runs a changing-colour mode and lets you speed it up or slow it down. That is the control most colour installations actually need: the choice is rarely “which colour” and usually “how fast, and how subtle”. A slow drift in a media room reads as considered; the same colours cycling quickly read as a disco.

What does the magnet do?

It holds the remote to the supplied bracket, and it matters more than it sounds. A remote that has a place on the wall gets used; one that lives in a drawer does not and a colour installation stuck on whatever it was left on is far more conspicuous than a plain one. Mount the bracket where a light switch would be. It still lifts off to use from the sofa, which a fixed plate cannot do.

What battery does it take, and how far does it reach?

Neither is recorded. Its tunable-white sibling takes two AAA cells, but we are not assuming the same for this one. No RF range figure exists in any source either in practice handsets of this kind work across a normal room and through a plasterboard wall, and RF needs no line of sight, which is what lets the receiver hide in a ceiling void. Ask us and we will confirm both.

Can I have a wall control as well?

Yes the CHAM-TOUCH-3C is the mains-wired glass wall plate with the same RGBW controls, and it talks to the same receiver. The sensible combination is the plate for everyday use where people look for a control, this remote for the sofa, and Bluetooth from a phone for setting scenes.
