   Learning the Code: Latching Mode 

   Important: In Latching Mode, you must program two different buttons — one for ON and one for OFF. (for this mode you need a different 433mhz remote with 2 buttons other than the one included)

   1. Press the learning button on the receiver three times

   2. The LED indicator will flash briefly and turn off, indicating it's in latching learning mode

   3. Press the remote button A (this will act as the ON command) – the LED flashes 5 times

   4. Press the remote button B (this will act as the OFF command) – the LED flashes 5 times again

   5. After 3 seconds, the LED turns back on – learning completed successfully

   Example:

   • Button A = ON

   • Button B = OFF

   ⏱️ Learning the Code: Time Delay Mode

   Time delay modes allow the relay to stay active for a set time after the remote is pressed.

   • 5-Second Delay: Press the learning button 4 times

   • 10-Second Delay: Press the learning button 5 times

   • 15-Second Delay: Press the learning button 6 times

   Steps:

   1. Press the learning button 4, 5, or 6 times depending on your desired delay time

   2. The LED will turn off – module enters delay learning mode

   3. Press the remote control button to pair

   4. The LED flashes and then turns off

   5. After 3 seconds, the LED turns on again – time delay learning successful

   ⚡ Power-On Function Learning (Auto-On After Power Loss)

   This feature allows the relay to automatically turn ON when power is restored (ideal for lights, alarms, etc.).

   1. Press the learning button 8 times in succession

   2. The LED indicator will blink once, then stay lit

   3. Press the remote button you wish to assign

   4. The LED will flash 3 times – power-on function learning successful

   Note:

   • This is also known as the “power-on auto-start” or “power restore activation” mode.

   • If you want to switch to other operating modes later, you must clear all codes first by resetting the receiver.
