5.1 General Connection Modes
Image: Diagrams illustrating various circuit connection modes for the QIACHIP KR2202, including AC power, DC power, and different load types.
This diagram shows common wiring setups for AC and DC loads. Pay close attention to the Live (L) and Neutral (N) connections for AC power, and Positive (+) and Negative (-) for DC power. The relay outputs provide Normally Open (NO), Common (COM), and Normally Closed (NC) contacts for flexible control.
5.2 Wiring Diagram for Motors

For controlling a DC motor with forward and reverse rotation, connect the AC 85-220V input to the 'IN' terminals. The DC motor's two wires are connected to terminals 5 and 2. The positive pole of the external DC power supply connects to terminals 6 and 3, and the negative pole connects to terminals 1 and 4. The live wire of the 220V AC power supply connects to the L interface, and the neutral wire to the N interface, powering the controller.
5.3 Wiring Diagram for Lights

To control two DC lamps, connect the positive poles of the lamps to terminals 6 and 3 respectively. The negative poles of the lamps connect to the negative pole of the external DC power supply. The positive pole of the external DC power supply connects to interfaces 5 and 2 respectively. The live wire of the AC power supply connects to the L interface, and the neutral wire connects to the N interface.
6. Remote Control Pairing and Operation
The KR2202 receiver supports Momentary, Toggle, and Latched modes. Follow these steps to pair your remote controls and set the desired operating mode.
6.1 Clearing Existing Codes
- Press the 'Learning Button' on the receiver module 8 times.
- The indicator light will flash and then go out, indicating that all previously paired remote controls have been cleared.
6.2 Momentary Mode Pairing
In Momentary mode, the relay activates only while the remote button is pressed and deactivates upon release.
- Press the 'Learning Button' on the receiver module 1 time. The indicator light will turn on.
- Press the first button (e.g., 'A') on your remote control. The indicator light will flash and then go out.
- Press the second button (e.g., 'B') on your remote control. The indicator light will flash and then go out.
- Pairing is successful. Now, pressing 'A' will activate one relay, and pressing 'B' will activate the other, as long as the button is held down.
6.3 Toggle Mode Pairing
In Toggle mode, pressing a button once activates the relay, and pressing the same button again deactivates it.
- Press the 'Learning Button' on the receiver module 2 times. The indicator light will turn on.
- Press the first button (e.g., 'A') on your remote control. The indicator light will flash and then go out.
- Press the second button (e.g., 'B') on your remote control. The indicator light will flash and then go out.
- Pairing is successful. Press 'A' to turn on/off the first relay, and 'B' to turn on/off the second relay.
6.4 Latched Mode Pairing
In Latched mode, pressing one button activates a relay, and pressing another button deactivates it. This mode typically requires a remote with at least two distinct buttons for each channel (e.g., 'A' for ON, 'B' for OFF).
- Press the 'Learning Button' on the receiver module 3 times. The indicator light will turn on.
- Press the first button (e.g., 'A') on your remote control. The indicator light will flash and then go out.
- Press the second button (e.g., 'B') on your remote control. The indicator light will flash and then go out.
- Pairing is successful. Press 'A' to activate the first relay, and 'B' to deactivate it.
Important Note for Latched Mode:
- A remote control will only match two buttons in Latched mode. Any extra buttons on a 4-button remote will not be paired.
- To change the mode for a remote, you must first clear all existing codes (Section 6.1) and then re-pair the remote in the desired mode.

8. Maintenance
- Battery Replacement: The remote controls require CR2032 batteries. Replace them when the transmission range decreases or the indicator light on the remote does not illuminate.
- Cleaning: Use a dry, soft cloth to clean the receiver module and remote controls. Avoid using liquids or abrasive cleaners.
- Antenna: Ensure the receiver's antenna is uncoiled and extended for optimal signal reception.
9. Troubleshooting
- Remote not responding: Check remote battery. Ensure the remote is paired correctly to the receiver in the desired mode. Verify the receiver has power.
- Reduced range: Replace remote battery. Ensure the receiver's antenna is fully extended and not obstructed. Minimize interference from other RF devices.
- Device not activating: Check all wiring connections for tightness and correctness. Verify the power supply to both the receiver and the controlled device. Ensure the relay contacts are properly connected to the load.
- Incorrect operation mode: Clear all codes and re-pair the remote in the correct Momentary, Toggle, or Latched mode as per Section 6.
