4. Setup and Installation

The Micro Switch G2 is designed to be installed behind an existing wall switch or within a light fixture box. Its compact size (3.15 x 2.76 x 1.18 inches) allows it to fit into standard electrical boxes.

4.1 Wiring Considerations

The Micro Switch G2 features screw terminals for electrical connections. It is recommended to use stranded wire for optimal connection security. Some units may come with pre-installed pigtails to facilitate wiring.

If a neutral wire is not available in the switch box, the unit can be installed in the light fixture box, provided a neutral wire is present there. The existing wires running to the wall switch can then be used to connect to the switch input terminals of the Micro Switch G2.

The device supports both 2-way and 3-way light switch configurations.

4.2 Z-Wave Network Inclusion

To include the Micro Switch G2 into your Z-Wave network:

1. Ensure the Micro Switch G2 is powered on.
2. Put your Z-Wave controller into inclusion/pairing mode. Refer to your controller's manual for specific instructions.
3. Press the S2 button on the Micro Switch G2 once. The device will attempt to pair with the controller.
4. Confirm successful inclusion on your Z-Wave controller.

5. Operating Instructions

5.1 Basic Operation

Once successfully included in a Z-Wave network, the connected light or appliance can be controlled via your Z-Wave controller or the physical wall switch. The physical switch will toggle the state of the connected load.

5.2 Configuration Parameters

The Micro Switch G2 can be configured for different switch types (e.g., momentary or standard toggle switch) using Z-Wave configuration parameters. A common parameter to adjust is:

• Parameter 120: Controls the switch type.
• Size: 1 byte dec
• Value 0: Configures the Micro Switch for a standard toggle switch (press once for ON, press again for OFF). This is often the desired setting for typical wall switches.
• Value 1: Configures the Micro Switch for a momentary push button.

Refer to your Z-Wave controller's interface for instructions on how to change device configuration parameters. Alternatively, some configurations can be changed by pressing and holding the S2 button for approximately 6 seconds, though this is less precise and may vary by firmware version.

6. Maintenance

The Aeotec Micro Switch G2 requires minimal maintenance. Ensure the device is kept dry and free from dust. Periodically check electrical connections for tightness, especially if any issues arise. Always disconnect power before performing any physical checks or cleaning.

7. Troubleshooting

• Light Flickers or Does Not Stay On: This often indicates an incorrect configuration for the type of physical switch connected. Ensure Parameter 120 is set to '0' for a standard toggle switch. If using a momentary switch, ensure it is set to '1'.
• Device Not Responding: Verify that the Micro Switch G2 is powered and properly included in your Z-Wave network. Check the circuit breaker and all wiring connections. Try re-including the device if necessary.
• Difficulty Fitting in Wall Box: Older or smaller metal workboxes may not provide sufficient space. Consider replacing the workbox with a larger, standard size if space is an issue. Ensure wires are neatly organized and properly secured.
• Fragile Connections / Shorting: Exercise caution when wiring. Use stranded wire and ensure all connections are secure but not overtightened. Insulate all exposed wire ends and connections properly with wire nuts and electrical tape to prevent accidental shorts. A short circuit can damage the unit.
• Z-Wave Exclusion Issues: If the device fails to exclude from the network, try performing a factory reset (refer to the manufacturer's specific instructions for factory reset, usually involving a sequence of button presses).
