4. Setup and Installation

4.1. Before You Begin

• Turn off power to the light switch circuit at the main circuit breaker.
• Verify that the power is off by attempting to turn on the light switch.
• Ensure you have the necessary tools: screwdriver, wire strippers, electrical tape.
• Confirm your electrical box has sufficient space for the Nano Dimmer in addition to existing wiring.

4.2. Wiring Diagrams

The Nano Dimmer can be wired in various configurations depending on your existing electrical system (with or without a neutral wire, 2-way or 3-way switch). Always ensure connections are secure and insulated.

Standard Wiring (with Neutral Wire)

• Connect the Live (L) wire from the mains to the 'L' terminal on the Nano Dimmer.
• Connect the Neutral (N) wire from the mains to the 'N' terminal on the Nano Dimmer.
• Connect the Load (OUT) wire (to the light fixture) to the 'OUT' terminal on the Nano Dimmer.
• Connect the Common (COM) wire from your wall switch to the 'COM' terminal on the Nano Dimmer.
• Connect the Switch 1 (S1) wire from your wall switch to the 'S1' terminal on the Nano Dimmer.
• If using a 3-way switch, connect the second traveler wire from the auxiliary switch to the 'S2' terminal.

2-Wire System Wiring (without Neutral Wire)

For installations without a neutral wire, the Nano Dimmer can still function. In this configuration, the 'N' terminal is not used. Ensure your load meets the minimum wattage requirement for stable operation (typically 20W for some LED/CFL bulbs, though the device may work with lower loads).

• Connect the Live (L) wire from the mains to the 'L' terminal on the Nano Dimmer.
• Connect the Load (OUT) wire (to the light fixture) to the 'OUT' terminal on the Nano Dimmer.
• Connect the Common (COM) wire from your wall switch to the 'COM' terminal on the Nano Dimmer.
• Connect the Switch 1 (S1) wire from your wall switch to the 'S1' terminal on the Nano Dimmer.

4.3. Physical Installation

• Once wired, carefully place the Nano Dimmer and all wires into the wall box. Ensure no wires are pinched or exposed.
• Mount your existing wall switch back into the electrical box.
• Restore power at the circuit breaker.

5. Operating Instructions

5.1. Adding to a Z-Wave Network (Inclusion)

To add your Nano Dimmer to a Z-Wave network, your Z-Wave gateway/controller must be in inclusion mode.

1. Put your Z-Wave controller into inclusion/pairing mode (refer to your controller's manual).
2. Press the Action Button on the Nano Dimmer once. The LED indicator will flash during the inclusion process.
3. If inclusion is successful, the LED will become solid. If it fails, the LED will flash rapidly and then turn off.

5.2. Removing from a Z-Wave Network (Exclusion)

To remove your Nano Dimmer from a Z-Wave network, your Z-Wave gateway/controller must be in exclusion mode.

1. Put your Z-Wave controller into exclusion/unpairing mode (refer to your controller's manual).
2. Press the Action Button on the Nano Dimmer once. The LED indicator will flash during the exclusion process.
3. If exclusion is successful, the LED will turn off.

5.3. Manual Control

Once installed and powered, your existing wall switch connected to the Nano Dimmer will function normally to turn the lights on/off and dim them (if supported by the switch type and configured correctly).

5.4. Advanced Configuration

The Nano Dimmer supports various Z-Wave configuration parameters to customize its behavior, such as dimming speed, external switch type detection, and power reporting. Refer to the official Aeotec documentation or your Z-Wave controller's interface for details on adjusting these parameters.

6. Maintenance

The Aeotec Nano Dimmer requires minimal maintenance. Ensure the device is kept dry and free from dust. Do not use harsh chemicals or abrasive cleaners. If cleaning is necessary, gently wipe with a dry, soft cloth. Periodically check wiring connections for tightness, ensuring power is off before inspection.

7. Troubleshooting

If you encounter issues with your Nano Dimmer, refer to the following common problems and solutions:

7.1. Factory Reset

A factory reset will remove the Nano Dimmer from any Z-Wave network and restore all settings to their default values. Only perform this if your primary controller is missing or inoperable.

1. Press and hold the Action Button for 20 seconds.
2. The LED will flash rapidly, then turn solid for a few seconds, then turn off, indicating a successful reset.
