User Manual for Niko Connected Dimmer 552-722X1

Quick guide from the manual

The Niko 552-722X1 is a 2-wire Zigbee connected dimmer designed for 230V lighting circuits. It can operate in stand-alone mode (switching/dimming its own contact) or be connected to a Zigbee smart hub for advanced control via the Niko Home Control app or programming software.

Installation and Wiring

Warning: Installation must be performed by a qualified installer. Always switch off the 230V power supply before starting work.

• Wiring: Connect the dimmer to the lighting circuit. The product must be secured with a miniature circuit breaker (MCB) of max. 16 A.
• Flush-mounting: The dimmer is designed for flush-mounting boxes with a minimum depth of 40 mm.
• Dismantling: Ensure power is OFF before removing the dimmer from the wall.

Zigbee Network Setup

To connect the dimmer to a Zigbee network:

1. Reset the device if it was previously connected to another network.
2. Follow the onboarding procedure in the Niko Home Control software or app.
3. Set the dimmer to pairing mode by pressing the switch button 3 times within 6 seconds. The blue LED will blink for up to 5 minutes.
4. The dimmer is successfully added when the blue LED stays ON for 4 seconds.

Configuration

Setting Minimum Light Intensity

Adjust the minimum dimming level to optimize the dimming range for your lamp:

1. Dim the lamp to the minimum level using the dimming button in the middle of the base.
2. If the lamp is too bright, reduce the minimum level using the MIN DIM LEVEL button.
3. If the lamp flashes or switches off, increase the minimum level using the same button.
4. Switch the dimmer off and back on to save the setting.

Selecting Dimmer Profile

If the lamp does not switch on or flickers, you may need to select a specific lamp profile (LED 1-8). The first button press 'Select Profile' indicates the currently configured profile by the number of green LED flashes.

Troubleshooting

If you encounter issues, check the following:

• Dimmer switches off suddenly: Check for thermal overload or short circuit. Ensure the load is not too high and the ambient temperature in the flush-mounting box does not exceed 35°C.
• Lamp flickers: Check if the lamp is dimmable. Adjust the minimum dimming level or install an LED compensator (310-05001) between the switching wire and the neutral wire.
• Cannot find dimmer in app: Ensure the distance between the dimmer and the smart hub is at least 2 meters and no more than 10 meters.
