5. Care and Maintenance

To ensure the longevity and proper functioning of your Lutron Sunnata On/Off Accessory Switch, follow these simple care and maintenance guidelines:

• Cleaning: Clean the switch with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
• Avoid Over-tightening: When installing or re-installing the wallplate, do not overtighten screws, which can cause cracking or damage.
• Environmental Conditions: Ensure the switch is installed in an environment within its specified operating temperature and humidity ranges.

6. Troubleshooting

If you experience issues with your Sunnata On/Off Accessory Switch, refer to the following common troubleshooting steps:

• Lights Not Responding: Ensure power is supplied to the circuit. Verify that the accessory switch is correctly wired to a compatible Sunnata LED+ dimmer.
• Intermittent Operation: Check all wiring connections for tightness and proper insulation. Ensure no wires are pinched or damaged.
• Accessory Switch Not Controlling Lights: Confirm that the main Sunnata LED+ dimmer is functioning correctly. The accessory switch relies on the dimmer for primary control.
• Flickering Lights: This may indicate an incompatibility with the connected LED bulbs or an issue with the main dimmer. Refer to the dimmer's manual or Lutron's LED compatibility tool.
