# Pairing reference

Every way to pair an iNELS Wireless controller, detector or shutter with a unit — and how to clear it again.

*Part 1, Understand the system. New to iNELS Wireless? Do* [*Tutorial 1*](/inels-home/inels-wireless/tutorial-1-your-first-button-and-light.md) *first, then come back here for the other cases.*

***

## Before you start

* The unit is wired and powered — a short press of PROG (under 1 s) switches its output.
* You know the unit's **PROG times** — [Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md). They differ between units.
* You know which **function** you want and how many presses that is — [Appendix B](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md).
* The controller battery is good, and you are near the unit.
* You will leave **about 1 s between presses**.

## Which controller do I have?

Controllers with a **pairing button** have a pairing symbol printed on the back. Where to find the button:

| Controller             | Pairing button                                                                         |
| ---------------------- | -------------------------------------------------------------------------------------- |
| RF KEY                 | On the side, near button 5                                                             |
| RFGB (round and sharp) | Press the upper mandrel with a paperclip — the battery pops up and uncovers the button |
| RFWB                   | Remove the controller flap                                                             |
| RFDW-71 / RFDW-271     | Use the PROG button on the glass panel                                                 |
| RFSW-62 / RFSW-262     | Use the PROG button on the glass panel                                                 |

No pairing button and no symbol → an older controller: use section B.

## A. Controllers with a pairing button

{% stepper %}
{% step %}

#### Controller into pairing mode

Hold the controller's pairing button for **1 s**. The red LED gives a short blink. Always do the controller first, then the unit.
{% endstep %}

{% step %}

#### Unit into programming mode

Hold **PROG** on the unit for its *enter programming* time ([Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md)) — for example **2 s** on a single-channel RFSAI, **3–5 s** on the two-channel RFSAI-62B-SL. The LED flashes once per second.

![Hold PROG on the unit](https://2503278529-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkoLW6hWCvDgagoswDVfD%2Fuploads%2F6BLMLkX6OgyImEVzK56d%2Funit-prog-hold.png?alt=media)
{% endstep %}

{% step %}

#### Choose the function

Press the controller button you want to use — **as many times as the function number** ([Appendix B](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md)), about 1 s apart. The unit's LED lights at each press.
{% endstep %}

{% step %}

#### Finish

Short press **PROG** on the unit (under 1 s), then short press the pairing button on the controller.

![Short press PROG](https://2503278529-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkoLW6hWCvDgagoswDVfD%2Fuploads%2Fanv7zhzbS1Z1vGwy03FT%2Funit-prog-short.png?alt=media)
{% endstep %}
{% endstepper %}

## B. Controllers without a pairing button

Older controllers are put into pairing by re-inserting the battery. There are two modes.

#### B1. Normal mode (without compatibility mode)

1. Remove the controller battery for **at least 5 s**, then insert it. The red LED lights for 3 s.
2. While it is lit, press and hold **button 1** until the LED gives **short double flashes**. Release.
3. Put the unit into programming mode ([Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md)).
4. Press the controller button the required number of times ([Appendix B](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md)).
5. Short press PROG on the unit, then remove and re-insert the controller battery.

#### B2. Compatibility mode (oldest units)

1. Remove the controller battery for **at least 5 s**, then insert it. The red LED lights for 3 s.
2. While it is lit, press and hold **buttons 1 + 2** until the LED **flashes rapidly**. Release.
3. Put the unit into programming mode.
4. Press the controller button the required number of times — switching functions 1–6, dimming functions 1–8.
5. Short press PROG on the unit.

The same procedure switches back: **double flash = normal mode, fast flashing = compatibility mode**.

{% hint style="info" %}

* With old controllers and old units you cannot tell in advance which mode is needed — try B1 first, then B2.
* The oldest RF Key/W and RF Key/B key fobs cannot be paired with units that have the radio-wave mark on the PROG button.
* RFSAI-62B-SL, RFSA-62B and RFDAC-71B pair differently from the rest — follow their own page.
  {% endhint %}

## C. Clearing and factory reset

**One button.** Hold PROG for the unit's *clear one button* time ([Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md)). The LED flashes 4× per second. Press the controller button you want to remove. One long flash confirms and the unit returns to normal operation.

**Whole memory = factory reset.** Hold PROG for the unit's *clear whole memory* time. All paired buttons are removed and the unit stays in programming mode (LED every 0.5 s, up to 4 min) — pair new buttons now, or short press PROG to leave.

Clearing does not change the unit's memory-function setting.

{% hint style="info" %}
There is **no separate "hold more than 12 s" factory reset**. Clearing the whole memory *is* the factory reset: **8 s** on single-channel RFSAI units, **12 s** on the two-channel RFSAI-62B-SL. Other units: [Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md).
{% endhint %}

## D. Detectors

A detector is a controller: it sends a command when triggered. Its behaviour is set with **DIP switches**, and it sends its pairing signal when you **insert the batteries**.

{% hint style="info" %}
The pictures show the **RFMD-200** motion detector. Other detectors are similar — see their own pages: [RFMD-100 / RFMD-200](/inels-home/inels-wireless/devices/transmitters/detectors/rfmd-100-rfmd-200.md) · [RFWD-100](/inels-home/inels-wireless/devices/transmitters/detectors/rfwd-100.md) · [RFSF-100](/inels-home/inels-wireless/devices/transmitters/detectors/rfsf-100.md). Set the DIP switches **before** pairing.

{% endcolumn %}
{% endcolumns %}

#### Immediate response

1. Set the DIP switches.
2. Put the receiving unit into programming mode ([Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md)).
3. Insert the batteries into the detector. If you just removed them, **wait 30 s** before inserting.
4. Short press PROG on the unit to finish.

![Insert the batteries](https://2503278529-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkoLW6hWCvDgagoswDVfD%2Fuploads%2FUGkKH1E4DHQuz7j3zJn5%2Frfmd-100-battery-insert.png?alt=media)

#### Delayed return with time setting

1. Set the DIP switches.
2. Put the receiving unit into programming mode.
3. Insert the batteries, then remove them. Do this **twice**, with a **30 s pause** each time before inserting.
4. Hold PROG on the unit **more than 5 s** — timing mode. Timing starts when you release PROG.
5. Wait for the time you want.
6. Insert the batteries — this stores the time.
7. Short press PROG on the unit to finish.

{% endcolumn %}
{% endcolumns %}

## E. Shutter units (RFJA)

1. Short press PROG on the RFJA (under 1 s) repeatedly until the shutter is at its **upper end position**.
2. Hold PROG **1 s** — programming mode, LED flashes once per second.
3. Press **one** button on the controller. It becomes **up**; the other half of the same rocker becomes **down** automatically.
4. Hold PROG **more than 5 s** — timing mode, LED flashes twice per second.
5. Press **down**. Release it **2 s after** the shutter stops at the lower end.
6. Press **up**. Release it **2 s after** the shutter stops at the upper end. The travel time is stored.
7. Short press PROG (under 1 s) to finish — the LED switches off.
