3.2 Installation of the Relay Module
Important: Ensure power is disconnected at the main circuit breaker before beginning any electrical installation. If you are unsure about electrical wiring, please consult a qualified electrician.
- Identify the Live (L) and Neutral (N) wires from your power source.
- Connect the Live wire to the 'L INPUT' terminal and the Neutral wire to the 'N INPUT' terminal on the relay module.
- Connect the Live wire of your light fixture or appliance to the 'L OUTPUT' terminal and the Neutral wire to the 'N OUTPUT' terminal on the relay module.
- Secure all wire connections firmly using the screw terminals.
- Mount the relay module in a suitable electrical box or location, ensuring it is protected and has adequate ventilation.
- Restore power and test the connection.

This image provides a clear wiring diagram for installing the smart relay module, showing connections for live wire, neutral wire, input, and output to a light or ceiling fan. It also includes precise dimensions of the module: 47mm (length), 42mm (width), and 23mm (height), along with its electrical specifications.
3.3 Pairing the Wireless Wall Switch
The wireless wall switch communicates with the relay module via RF (Radio Frequency). Follow these steps to pair them:
- Ensure the relay module is powered on.
- Press and hold the pairing button on the relay module for approximately 3-5 seconds until the indicator light starts blinking rapidly.
- Within 10 seconds, press any button on the wireless wall switch you wish to pair.
- The indicator light on the relay module will stop blinking and remain solid for a moment, indicating successful pairing.
- Repeat the process for additional wall switches or to pair one switch with multiple receivers.

This diagram explains the flexible pairing options of the DieseRC system. It shows how multiple wireless wall switches can control a single receiver, and conversely, how one wireless wall switch can control multiple receivers, allowing for customized control setups.
