Help: FDXS35EAVMB indoor unit with RXS35G2V1B inverter outdoor unit

[papper110]

Hello,

Can you recommend a remote control for the Daikin FDXS35EAVMB indoor unit (outdoor RXS35G2V1B), because mine is missing? The infrared receiver part is also missing.
I am interested in both wired and wireless solutions. Unfortunately, there is a lot of information on the internet, but I have not been able to find the exact compatibility list. (I unfortunately know that this is a problematic and unique pair.)

I bought a Faikin module (ESP32-S3-MINI-1/ 2024.08.06. I also performed the flashing due to a Wi-Fi issue), but I cannot start the outdoor unit with it. The issue: the Faikin is alive. I can see everything in the "app", and the LED on the board also provides feedback, e.g., heating, but nothing happens.
One thing works: the FAN. It is well controlled, and the fan speed (RPM) is displayed, and I can adjust it from 1-5. However, any operation involving starting the outdoor unit fails.( The outdoor unit is working perfectly. By pressing the forced operation button on it, it turns on and blows cold air.)
I DO NOT have an infrared controller that also includes the thermometer. Could this be the issue? In the app, I see an internal temperature of -32°C (I've already ordered a BLE sensor, which I hope will help with the problem). Currently, I only have the Faikin module connected to the S21 port for control.

(I cannot obtain it because after reading thousands of pages of Daikin PDFs, I have not found any information about the exact model. Official inquiries to Daikin lead to chatbot responses or rejections.)

Could you suggest any solution to my problem? Maybe someone who has such an indoor unit could tell me the exact model of the original infrared receiver unit? It would be a huge help because currently, there is no heating in the house where we live.
I know that this model is not on the official Daikin support list, but I couldn't find anything else, so I had to try it. I hope my struggle helps others as well!"
