Method 2: Using Device Button

1. Press and hold the device button for more than 10 seconds until the LED indicator enters breathing mode.
2. Briefly press the device button to enter "Manual Calibration" mode.
3. Manually open the curtains completely, then briefly press the device button until the LED indicator flashes three times.
4. Wait for the device to automatically close the curtains, then briefly press the device button again until the LED indicator flashes three times. This completes the "Manual Calibration".

*If there is any deviation in the calibration result, the calibration can be repeated until the desired accuracy is achieved.

*As the maximum one-way allowable continuous operation time for the motor in this device is 2 minutes, please pause the operation before the curtain reaches its limit position to avoid damaging the motor.

3.6 Install in Mounting Box

The MINI-ZBRBS is designed for complete installation into a flush-mounted box and enclosed with a cover plate or switch that fulfills national standard requirements. Ensure no part of the product is exposed after installation.

*The depth of the mounting box should be at least 60 mm.

4. Operation

4.1 External Switch Control

The MINI-ZBRBS supports various external switch types, with the default factory setting being a rocker switch (Edge Mode).

• Rocker Switch: Toggle the "UP" and "DOWN" keys alternately more than 3 times within 6 seconds to control the curtain.
• Momentary Switch: Press the "UP" key more than 6 times within 6 seconds to control the curtain.

To switch the external switch type: Short-press the button on the device three times. The blue light will flash 3 times, indicating the switch type has been successfully switched. The sequence is: Edge Mode → Pulse Mode → Following Mode.

4.2 App Remote Control

Once paired with the eWeLink app via a Zigbee hub, you can control your roller shutters remotely from your smartphone or tablet. This includes opening, closing, pausing, and setting specific percentage levels.
