- Install in accordance with all national and local codes.
- Hire a professional electrician if you are not familiar or not comfortable with electrical work, or if the wiring in your electrical box differs from the pictures.
- A Neutral Wire is required.
iotty U2 Switch Components:
- 1 U2 Backplate [containing 6 wires (leads) labeled]:
- 1 ‘L’ - Line or ‘Live’ wire
- 1 ‘N’ - Neutral wire
- 2 RL1 wires - [a left lead wire and right lead wire]
- 2 RL2 wires - [a left lead wire and right lead wire] RL1 Controls the left switch. RL2 Controls the right switch.
- 1 Small Bag containing 4 screws and 6 screw caps (orange)
- 1 U2 Faceplate
Step 1) Turn OFF the power at the circuit breaker for the switch you are replacing.
Step 2) Verify power is off. Pull out your old switch and label your wires.
*The Ground Wire (Copper Wire) can be tucked neatly into the back of the box, iotty smart switch devices do not use a ground wire.
*The Neutral Wire (Normally White) is typically covered by a cap and has two or more wires twisted together inside the box.
*The Line Wire (Live) is what brings power to the box and is always active as long as the power supply is on.
*The Load Wire (Wire to fixture) is what brings power to the box and controls power to the fixture.
Step 3) The iotty U2 Smart Switch has 6 wires; labeled L (for Line/Live), N (Neutral), RL1 (2 wires for Line/Live or Load). RL2 (2 wires for Line/Live or Load). Either of the RL1 & RL2 wires can connect to the Line or Load.
- Connect ‘L’ to the right Hot (Live) Wire.
- Connect the ‘N’ to the neutral bundle and cap them off.
- The RL2 has 2 wires, connect either one to the load and the other to the L (Hot/Live) wire of the right switch.
- If you have a ground wire (typically exposed copper) place it into the wall box neatly (it is not needed for installation).
- The RL1 has 2 wires, connect either one to the load and the other to the Hot/Live wire of the left switch.
- Make sure the connections are strong by holding and pulling on the wires.
Step 4) Screw in the Backplate, using the holes as shown.
- Push all the wires back into the wall box and try to allow as much space as possible. (Do not push the wires using the back of the switch).
- Insert the Backplate in the wall and use the box screws to fasten.
- Position the switch so that the small buttons are located at the bottom and you can read the text right side up, as shown.
Step 5) Attach the Faceplate.
- With your hands only, carefully position the Faceplate so that the little circle is located at the bottom of the rectangle and apply gentle pressure with two fingers at the top and bottom of the Faceplate, you will hear the plate attach to the Backplate.
- Once installed, the Faceplate should not be loose or move.
- If necessary, to remove, pull away at the bottom of the device until you hear a click then lift off. Do not pull the Faceplate when removing, lift only. Please see our Help Article here for more information.
Step 6) Congratulations! Your U2 iotty Smart Switch is now installed and ready for use! Turn power ON at the circuit breaker.
