Successfully Configuring ZXT-120 for Daikin AC Control

I wanted to share my experience in configuring the ZXT-120 for controlling my Daikin AC unit. Initially, I faced some challenges with getting the ZXT-120 to learn the AC codes properly, but after some trial and error, I managed to get it working smoothly. Here’s how I did it:

  1. Understanding the Parameters: I realized that the parameters needed careful adjustment. I started by setting Parameter 27 to 000 in decimal, which put the ZXT-120 into learning mode. I made sure to save this setting and waited for the unit to flash twice, confirming it was ready.

  2. Learning the Codes: I then navigated to Parameter 25 and set the desired value to 1. This step is crucial for initiating the learning process. After saving, I pointed the Daikin remote at the ZXT-120 and pressed the button I wanted to program. The ZXT-120 flashed six times, indicating a successful learn.

  3. Testing the Setup: Once the codes were learned, I tested the setup by toggling the AC on and off using the ZXT-120. It worked perfectly, allowing me to control the AC without needing the remote. I even managed to set the fan speed to high, which was my main goal.

  4. Tips for Others: If you’re having trouble, make sure to reset the ZXT-120 to factory settings before starting the process. Also, ensure that the remote you’re using is in range and that the ZXT-120 is in learning mode throughout the process.

This setup has made controlling my AC much more convenient, especially since I can now integrate it with my smart home system. I hope this helps anyone else trying to get their ZXT-120 working with a Daikin AC!
