1. Product Overview
The Qiulaofu 433MHz Wireless 2-Channel AC Relay Receiver Smart Switch is designed for remote control of various AC electrical devices. This intelligent switch allows you to control two independent electrical devices simultaneously, such as lights, fans, or motors for curtains, roller shutters, blinds, garage doors, and gates. It operates on AC 90V-250V and features a 10A relay with a recommended load of less than 5A or 500W for optimal performance. The RF technology ensures stable signal transmission, capable of passing through walls, floors, and doors, with a maximum range of up to 328ft (100m) in open areas.

6. Operating Modes and Programming
The receiver supports Momentary, Toggle, and Latched (+ Stop) modes. The default mode is Latched (+ Stop). To change the operating mode, you must first reset the receiver and then program it with the remote control in the desired mode.
6.1 Momentary Mode
In Momentary Mode, the relay turns on only while the remote button is pressed and held. It turns off when the button is released.
Programming Momentary Mode:
- Press the learning button on the receiver 1 time. The indicator LED on the receiver will light up.
- Press button "A" on the remote control. The indicator LED on the receiver will flash several times and then turn off.
- Press button "B" on the remote control. The indicator LED on the receiver will flash several times and then turn off. Programming is complete.
6.2 Toggle Mode
In Toggle Mode, pressing a button once turns the relay on, and pressing the same button again turns it off.
Programming Toggle Mode:
- Press the learning button on the receiver 2 times. The indicator LED on the receiver will light up.
- Press button "A" on the remote control. The indicator LED on the receiver will flash several times and then turn off.
- Press button "B" on the remote control. The indicator LED on the receiver will flash several times and then turn off. Programming is complete.
6.3 Latched Mode (Default)
In Latched Mode, pressing button "A" turns relay 1 on. Pressing button "B" turns relay 2 on and simultaneously turns relay 1 off. Pressing button "C" turns both relay 1 and relay 2 off. This mode is recommended for controlling devices like curtain motors where specific actions (up, stop, down) are needed.
Programming Latched Mode:
- Press the learning button on the receiver 3 times. The indicator LED on the receiver will light up.
- Press button "A" on the remote control. The indicator LED on the receiver will flash several times and then turn off.
- Press button "B" on the remote control. The indicator LED on the receiver will flash several times and then turn off. Programming is complete.

6.4 Resetting the Receiver (Clearing Data)
To clear all programmed remote controls and operating modes from the receiver, perform a reset. This is necessary before changing the operating mode of a remote control.
Reset Procedure:
- Press the learning button on the receiver 9 times. The indicator LED on the receiver will flash several times and then turn off. Reset is complete.
- Note: After a reset, all previously paired remote controls will no longer work and must be reprogrammed.

8. Troubleshooting
- Remote control not working after setup: Ensure the receiver was reset before programming a new mode. All remotes need to be reprogrammed after a reset.
- Weak signal or intermittent control:
- Replace the remote control battery if its voltage is low.
- Slightly stretch the antenna on the receiver for better signal reception.
- Ensure there are no major obstructions or sources of interference between the remote and the receiver.
- Device not responding:
- Check all wiring connections to ensure they are secure and correct.
- Verify that the power supply to the receiver is active (AC 90V-250V).
- Confirm that the connected device is within the recommended load limits (less than 5A or 500W).
- Latched mode not working as expected: Ensure the remote control has at least 3 or more buttons for proper functionality in Latched mode.
