5. Setup & Installation
5.1 Wiring Diagram
Before wiring, ensure the main power supply is OFF. Connect the AC input (Live and Neutral) to the receiver's input terminals. Connect your appliance (e.g., light, pump) to the receiver's output terminals (Live and Neutral). The receiver acts as a switch for the Live line.


5.2 Programming Operating Modes
The receiver supports multiple operating modes. To program a mode, follow these steps:
- Momentary Mode (Mode 1):
Press the learning button on the receiver 1 time. The indicator light will flash once. Then, press any button on your remote control. The indicator light will flash three times, indicating successful pairing in Momentary Mode. In this mode, the output is ON only while the remote button is pressed. - Toggle Mode (Mode 2):
Press the learning button on the receiver 2 times. The indicator light will flash twice. Then, press any button on your remote control. The indicator light will flash three times, indicating successful pairing in Toggle Mode. In this mode, one press of the remote button turns the output ON, and another press turns it OFF. - Latched Mode (Mode 3):
Press the learning button on the receiver 3 times. The indicator light will flash three times. Then, press the 'ON' button on your remote control, followed by the 'OFF' button. The indicator light will flash three times, indicating successful pairing in Latched Mode. In this mode, the 'ON' button turns the output ON, and the 'OFF' button turns it OFF. - Delay Mode (Mode 4/5/6/7):
Press the learning button on the receiver 4 times for a 5-second delay.
Press the learning button on the receiver 5 times for a 10-second delay.
Press the learning button on the receiver 6 times for a 15-second delay.
Press the learning button on the receiver 7 times for a 20-second delay.
After pressing the learning button the desired number of times, the indicator light will flash accordingly. Then, press any button on your remote control. The indicator light will flash three times. In Delay Mode, pressing the remote button turns the output ON, and it will automatically turn OFF after the set delay time.
5.3 Resetting the Receiver
To clear all learned remote controls and reset the receiver to its default state:
- Press the learning button on the receiver 8 times. The indicator light will flash eight times and then turn off, indicating a successful reset. After a reset, the remote control will no longer function until re-paired.
