Function Description and Setting Method

Available modes: (1) Momentary mode; (2) Toggle mode; (3) Latching mode; (4) Reset function; (5) Power-On Auto-Engagement.

  • Once paired and a working mode is set, the receiving module will keep this mode even after power off and power on again.
  • Requires QIACHIP brand remote controls and controllers. Compatibility with other brands is not guaranteed.
  • All modes require an external switch/button to be connected before use.

(1) Momentary Mode

Press and hold the transmitter button → output pin goes HIGH. Release → output returns LOW.

How to set:

  1. Click the external learning button 4 times. LED flashes 4 times then stays on.
  2. Press the transmitter button. LED flashes then turns off — Momentary mode set successfully.

(2) Toggle Mode

Press transmitter button → output HIGH and stays HIGH. Press again → output returns LOW.

How to set:

  1. Click the external learning button 2 times. LED flashes 2 times then stays on.
  2. Press any transmitter button. LED flashes continuously then turns off — Toggle mode set successfully.

(3) Latching Mode

Two transmitter buttons control HIGH and LOW output respectively.

How to set:

  1. Click the external learning button 3 times. LED flashes 3 times then stays on.
  2. Press one transmitter button. LED flashes then stays on.
  3. Press another transmitter button. LED flashes continuously then turns off — Latching mode set successfully.

(4) Reset Function

Clears all paired transmitters.

How to reset: Click the external learning button 8 times. LED flashes 8 times then turns off — reset complete.

(5) Power-On Auto-Engagement

After power-on, the output pin directly outputs HIGH level.

How to set: Press the learning button 6 times. LED flashes then turns off, output pin goes HIGH.

NOTE

  1. This product is a CMOS device. Please take anti-static precautions during storage, transportation and operation.
  2. Ensure proper grounding when using the device.
  3. RF devices are voltage-sensitive. If the power supply is unstable, add filtering at the power input terminal to ensure voltage does not exceed the maximum operating voltage.
