  • 2S (2-Second Delay):

  • BULB (Long Exposure):


  • (Only in Repeater Mode) The WTR2 has a "Disconnect Threshold" setting (usually -70dBm to -90dBm). If the main router’s signal drops below this level, the WTR2 will stop trying to connect.

    Q: Can I use multiple transmitters with one receiver?
    A: Yes, the Aodelan WTR2 can learn up to 4 transmitters in rolling code mode. Pair each one using the same procedure.

    Q: My receiver has 6 terminals, but the manual shows 8. Why?
    A: Older or budget versions combine COM and STOP internally. Check the label on your specific unit. aodelan wtr2 user manual

    Q: Is the Aodelan WTR2 compatible with 110V AC?
    A: The receiver operates on 12/24V DC only. For 110V AC, you must use an intermediate relay or power supply.

    A: Rapid flashing (5x per second) indicates a stuck button. Check for debris under the keypad.

    Q: Where can I download the original PDF manual?
    A: Aodelan does not maintain a public archive. Visit the retailer’s support page or contact the seller directly. Use this guide as the most complete replacement. | Problem | Likely Cause | Solution |
