Setup & Installation
Follow these steps to install and set up your DieseRC Smart Wireless Roller Shutter Controller Module.
1. Wiring the Module
Ensure power is disconnected at the main circuit breaker before proceeding with any wiring. This module is designed for 4-wire AC motors (two phase wires for input, one neutral wire, and one ground wire). The module can be installed with or without an existing manual panel switch.

- Disconnect Power: Turn off the power supply to the circuit at the main breaker.
- Identify Wires: Identify the Live (L), Neutral (N), Motor Up (L1), Motor Down (L2), and Ground (E) wires from your AC motor and power supply.
- Connect Power: Connect the Live (L) wire from your power supply to the 'L' terminal on the module and the Neutral (N) wire to the 'N' terminal on the module.
- Connect Motor: Connect the Motor Up wire to the 'L1' terminal and the Motor Down wire to the 'L2' terminal on the module. Connect the motor's Neutral wire to the 'N' terminal designated for the motor. Ensure the Ground wire is properly connected to the motor and electrical box.
- Connect Panel Switch (Optional): If using a manual panel switch, connect its output wires to the 'S1' (Up) and 'S2' (Down) terminals on the module. The common wire of the switch connects to the 'L' terminal on the module.
- Secure Module: Place the compact module within the electrical box or junction box, ensuring no wires are pinched.
- Restore Power: Once all connections are secure, restore power at the circuit breaker.

2. Resetting the Module (if necessary)
If the module is not in pairing mode (blue LED blinking) or you wish to clear existing pairings, you may need to reset it.
- Reset for Wi-Fi Pairing: Press and hold the learning button on the module for approximately 5 seconds. The blue LED indicator will start blinking rapidly, indicating that the module is in Wi-Fi pairing mode.
- Clear RF Remote Pairing: To clear all paired RF remote controls, press the learning button on the module 8 times. The module will confirm the clearing process. After resetting, the previously paired RF remote will no longer control the module.

3. Wi-Fi Pairing with Tuya/Smart Life App
To enable smart control, pair the module with the Tuya Smart or Smart Life app.
- Download App: Download and install the "Tuya Smart" or "Smart Life" app from your mobile app store. Create an account or log in.
- Enable Wi-Fi & Bluetooth: Ensure your smartphone's Wi-Fi (2.4GHz network) and Bluetooth are enabled.
- Enter Pairing Mode: If not already, reset the module by pressing and holding the learning button for 5 seconds until the blue LED blinks rapidly.
- Add Device: Open the app, tap the "+" icon to add a device. The app should automatically discover the "Curtain Switch" or similar device. If not, select "Add Manually" and choose "Curtain Switch (Wi-Fi)".
- Confirm Pairing: Follow the on-screen prompts to confirm the device and enter your 2.4GHz Wi-Fi network password. The module will connect to your Wi-Fi network.
- Rename Device: Once connected, you can rename the device for easier identification (e.g., "Living Room Blinds").

Troubleshooting
If you encounter issues with your DieseRC Smart Wireless Roller Shutter Controller Module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not responding to APP/RF remote. | No power, Wi-Fi disconnected, RF remote not paired, remote battery low. | Check power supply. Ensure Wi-Fi is stable (2.4GHz). Re-pair RF remote (see Setup section). Replace remote battery. |
| Roller shutter moves in the wrong direction (Up button closes, Down button opens). | Motor wires L1 and L2 are reversed. | In the Tuya/Smart Life app, go to Device Settings -> Motor Steering Switch and select "Reverse". Alternatively, disconnect power and swap the L1 and L2 motor wires at the module. |
| Module cannot be added to Tuya/Smart Life app. | Module not in pairing mode, incorrect Wi-Fi password, 5GHz Wi-Fi network, Bluetooth off. | Ensure module LED is blinking rapidly (reset if necessary). Verify Wi-Fi password. Connect to a 2.4GHz Wi-Fi network. Ensure Bluetooth is enabled on your phone. |
| Voice control (Alexa/Google Home) not working. | Account not linked, device not discovered, incorrect commands. | Ensure Tuya/Smart Life account is linked in Alexa/Google Home app. Ask assistant to "discover devices". Use correct voice commands as listed in Operating Instructions. |
| Roller shutter stops prematurely or doesn't reach full open/close. | App limit settings, motor calibration. | Check percentage settings in the app. Adjust the motor running time in the app settings (e.g., from default 120s to 20s or 30s as needed). |
