Read with the* [*Pairing reference*](/inels-home/inels-wireless/pairing-and-configuration.md)*.* Most iNELS Wireless transmitters can be paired with most receivers. The exceptions are old controllers, detectors, shutter units and a few units that pair in their own way. This page collects the rules. {% hint style="info" %} For a specific pair of units, see the unit's own page and its instruction manual. {% endhint %} ## 1. Quick answer | Transmitter | Switch units (RFSA, RFSAI, RFUS, RFSC) | Dimmers (RFDEL, RFDA, RFDSC) | Shutter units (RFJA) | | ------------------------------------------------------------------------------- | ---------------------------------------------------- | ------------------------------------------------------------------------------------ | ------------------------------------------------------ | | Controllers **with a pairing button** (RFWB, RFGB, RF KEY, glass RFSW and RFDW) | Yes | Yes | Yes | | **Older controllers** without a pairing button | Yes, in normal or compatibility mode — see section 4 | Yes, same rules | Yes, same rules | | **Detectors** RFMD-100, RFWD-100, RFSF-100 | Yes, but only units marked **RFIO2** | Yes, units marked RFIO2 (for example RFDEL-71B-SL); check the unit's page for others | **No** — detectors cannot be paired with shutter units | | **System units** (eLAN, RF Touch, RFTC-3) | Yes, by the address printed on the unit | Yes, same | Yes, same | {% hint style="info" %} RFSAI-62B-SL, RFSA-62B and RFDAC-71B pair a little differently from the rest. Always follow the unit's own page for them ([Appendix A](/inels-home/inels-wireless/appendix-a-prog-button-times.md) has their PROG times). {% endhint %} ## 2. RFIO and RFIO2 The radio language of the system is called **RFIO**. A newer version, **RFIO2**, is fully compatible with RFIO and adds more. Units that carry the RFIO2 mark can do the following: * **Work with older RFIO products.** Backward compatibility is kept. * **Act as a repeater** for other units. This is switched on with the RFAF/USB service key. * **Have their firmware updated** with the RFAF/USB service key. * **Communicate with the RFMD-100 and RFWD-100 detectors.** * **Pass on messages:** other receivers in range can help carry a message to a receiver that is out of reach. In unit manuals the same family is also written as "iNELS RF Control2 (RFIO2)". Older manuals call the whole system "iNELS RF Control". {% hint style="info" %} Look for the RFIO2 mark on the unit or on its page to see whether it supports these functions. {% endhint %} ## 3. Old and new controllers Controllers come in two generations, by factory version. | | Newer controllers | Older controllers | | ------------------------------------- | --------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- | | Pairing button and symbol on the back | **Yes** | No | | How you start pairing | Hold the pairing button 1 s ([Pairing reference, section A](/inels-home/inels-wireless/pairing-and-configuration.md)) | Remove the battery for at least 5 s and put it back ([section B](/inels-home/inels-wireless/pairing-and-configuration.md)) | | Pairing mode | Always the "RFIO2" way: controller **and** unit both go into pairing mode | Normal mode (double flash) or compatibility mode (fast flash) | Newly produced controllers work in RFIO2 mode and are taught to a unit differently from before. This prevents a random controller in range from being learned by mistake. A controller can still be switched into **compatibility mode** to pair the older, simpler way. #### Which mode is my controller in? | LED on the controller | Mode | | -------------------------------------------------- | ------------------- | | **Double flash** (flash, flash, gap, flash, flash) | Normal / RFIO2 mode | | **Fast flashing** | Compatibility mode | To change the mode, remove the battery for at least 5 s and put it back. While the red LED is lit (3 s), press and hold two buttons together until the LED shows the new mode, then release: | Controller | Buttons to hold | | --------------------- | --------------- | | RFWB, RFGB (standard) | 1 and 2 | | RF KEY-40 / RF KEY-60 | **1 and 3** | Keep holding until the LED shows the new mode (double flash or fast flashing), then release. Controllers that have a PROG button offer a second way: hold it for 8 s. The LED under the button lights while it is held. After 8 s it shows the new mode with double flash or fast flashing. Each 8 s press switches to the other mode. ## 4. Rules for the oldest controllers 1. **You cannot tell in advance** whether an older controller and an older unit need compatibility mode. Try normal mode first, then compatibility mode. ([Pairing reference, section B](/inels-home/inels-wireless/pairing-and-configuration.md)) 2. The oldest **RF Key/W** and **RF Key/B** key fobs, and other controllers of the oldest version, **cannot** be paired with units that have the **radio-wave mark** on the PROG button. 3. **RFSAI-62B-SL, RFSA-62B and RFDAC-71B** pair differently from other units. Follow their own page. 4. In compatibility mode the number of presses gives **functions 1–6 for switch units** and **1–8 for dimmers**. 5. Leave 1 s between presses in every mode. ## 5. Which function table does a receiver use? The number of presses means different things on different receivers. | Receiver family | Units | Presses | Table | | --------------------------------- | ----------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ | | Switch units, **multi-function** | RFSA-61B, RFSA-62B, RFSA-61M, RFSA-61MI, RFSA-66M, RFSA-66MI, RFSAI-61B-SL, RFSAI-62B-SL, RFSC-61N, RFUS-61 | 1×–6× | [Appendix B, switch units](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md) | | Switch units, **single function** | RFSA-11B, RFSAI-11B-SL | 1× (the button below gets OFF automatically) | [Appendix B, single function](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md) | | **Dimmers** | RFDA-73M/RGB, RFDEL-71B-SL, RFDEL-71M, RFDSC-71N, RFDAC-71B, RFDW-71 | 1×–8× | [Appendix B, dimmers](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md) | | **Shutter units** | RFJA | Not counted: first button = up, the other half of the rocker = down | [Pairing reference, section E](/inels-home/inels-wireless/pairing-and-configuration.md) | ## 6. Detectors A detector behaves like a controller, but it is paired when the **batteries are inserted**, and it needs a receiver marked **RFIO2**. | Detector | Can be paired with | | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **RFWD-100** window/door | RFSA-61B, RFSA-62B, RFSAI-61B, RFSA-61M, RFSA-66M, RFSC-61, RFUS-61 (only units marked RFIO2). System units eLAN-RF-003, eLAN-RF-Wi-003 | | **RFSF-100** flood | All switching units of the system **except blind units** that are marked RFIO2 (for example RFSA-11B, RFSA-61M, RFSA-66M, RFUS-61, RFSC-61). System units eLAN-RF, RF Touch, iNELS BUS central units CU3-0xM | | **RFMD-100** motion | Switching units marked RFIO2 and eLAN-RF system units | The detector's DIP switch tells it whether it is paired directly with a unit (position OFF) or connected to a system unit such as a gateway (position ON). See [Tutorial 5](/inels-home/inels-wireless/tutorial-5-detectors-motion-light-door-or-window-flood.md) for where the switch is. ## 7. Transmitters of the system These controllers are the transmitters of the system: * **Surface or wall mounted:** RFWB-20/MPW, RFWB-40/MPW, RFWB-20/G, RFWB-40/G, RFWB-40G/MT, RFGB-20, RFGB-40, RFGB-40B/MT, RFGB-40W/MT, RFGB-220, RFGB-240, RFTC-10/G, RFTC-50/G. * **Flush mounted:** RFSK-21/MPW, RFDK-21/MPW, RFJK-22/MPW, RF Touch-2, RFDW-71, RFDW-271, RFSW-62, RFSW-62/S, RFSW-22, RFSW-42, RFGS-30/S, RFMB-22, RFMB-42, RFMB-62. Some of these also have an output of their own (for example RFSK-21/MPW with a relay), so they are transmitter and receiver at once. See [Transmitters, receivers and gateways](/inels-home/inels-wireless/transmitters-receivers-and-gateways.md). *** **See also:** [Appendix A — PROG button times](/inels-home/inels-wireless/appendix-a-prog-button-times.md) · [Appendix B — Functions by number of presses](/inels-home/inels-wireless/appendix-b-functions-by-number-of-presses.md) · [Pairing reference](/inels-home/inels-wireless/pairing-and-configuration.md)
