The Domus CHAM-REM-2C is a handheld RF and Bluetooth remote control fortunable-white LED strip, running on two AAA batteries, withscene memory and a wall-mounting bracket.

On its own, this remote does nothing. It is one half of asystem: it transmits to the CHAM-BT-RF-5C receiver, which sits between your driver andyour LED strip and does the actual work.

Without that receiver there is nothing for it to talk to and neither thetitle nor the product record says so. If you are ordering a tunable-white strip installation, you needthree things: the strip, the receiver, and this remote. Tell us what strip youare running and we will specify the whole chain rather than leave you to discover the gap.

Our record also describes this remote as having a built-in LED. It doesnot it is a battery-powered handset with no light source in it at all. We are correctingthe page rather than repeating the field.

What tunable white means, and why it needs a controller

• Tunable-white strip carries two sets of LEDs one warm, one cool onthe same tape. Mixing them gives you any colour temperature between the two, not threefixed steps.
• That mixing has to happen somewhere, and it is not in the strip and not in thedriver. It is in the receiver, which this remote commands.
• The difference from a dip-switch fitting is control after installation. Aswitchable downlight is set once, on a ladder. This is adjusted from the sofa, whenever you like.

What the remote actually does

• Selects the white point anywhere across the tunable range.
• Dims the strip independently of the colour.
• Saves scenes. This is the part people use most a warm dim setting forevening and a bright neutral one for working, both a single press away rather than two adjustments eachtime.
• Two channels, so it can control two zones.
• RF and Bluetooth. RF does not need line of sight, so the receiver can behidden in a ceiling void or behind joinery.

Living with it

• Two AAA batteries (4.5V). No charging, no dock, and it keeps working in apower cut once the lights come back.
• The mounting bracket is the detail worth using. A remote that has a place on thewall gets used; one that lives in a drawer does not, and an expensive tunable-white installation ends upstuck on whatever setting it was left on.
• Rated 040C. Indoor use.
• No RF range figure is published in any source we hold. In practice RF handsets ofthis kind work across a normal room and through a plasterboard wall, but we are not putting a number toit. Ask us if the receiver will be a long way from where you sit.

Where it works

• Tunable-white LED strip installations using the CHAM-BT-RF-5C receiver.
• Living rooms, bedrooms and studies anywhere the light needs to change through the day.
• Two-zone installations two channels.
• Not a standalone dimmer, and not a replacement for a wall plate.
• Not usable without the receiver.
• Indoor, 040C.

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 mixing and dimming. Neither the title nor our product record says so, which is why we are saying it here. A tunable-white installation needs three things: the strip, the receiver and this remote.

What is tunable white, and how is it different from a switchable fitting?

Tunable-white strip carries two sets of LEDs, one warm and one cool, on the same tape. Mixing them gives you any colour temperature between the two rather than three fixed steps and the mixing happens in the receiver, which this remote commands. The practical difference is when you choose: a switchable downlight is set once on a ladder, this is adjusted from the sofa whenever you like.

Does it dim as well as change colour?

Yes, and independently you can set a warm white and then take the level down without the colour shifting back. It also saves scenes, which is the feature people actually use: a warm dim setting for the evening and a bright neutral one for working, each a single press away.

How many zones can it control?

Two channels, so two zones from one handset. If you are running more than that, tell us what you are lighting and we will specify the right combination of receivers.

Does the receiver need line of sight?

No that is why it is RF as well as Bluetooth. The receiver can be hidden in a ceiling void or behind joinery and still respond. No range figure is published in any source we hold, so if the receiver will be a long way from where you sit, ask us before you commit to the layout.

Does it have a light on it?

No. Our product record lists a “built-in LED” for this item, and that is simply the wrong field it is a battery-powered handset with no light source in it at all. We have corrected the page rather than repeat the record.

What batteries does it take and what warranty does it have?

Two AAA batteries, 4.5V no charging and no dock, and it keeps working after a power cut once the lights come back. The warranty term is not recorded on this listing at all, which is unusual for Domus; ask us and we will confirm it in writing before you order.
