How to install a Faikin and cable

Follow the steps:

  1. Open the cover of the Daikin unit.
  2. Locate the control board slot (typically used for the factory WiFi module)
  3. Plug the Faikin into the slot. (now you've got local web interface control via WiFi, stops offshore connection and cloud services, and removes the need for Daikin app).
  4. Choose from three operation platforms and install your preference.
  5. Complete your automated control preference setup using the plaform.

(The module can also interface with compatible BLE temperature sensors as an external reference.)

Tip: Before purchasing, we recommend buyers read carefully the ESP32-Faikin GitHub repo. Check your unit serial number appears on the confirmed list of working air-con units.

*All Faikin models contain preloaded software (flashed). Each Faikin model is individually tested for quality control and reliability to ensure it is plug-in ready.
