NTC - Carrier Room Controller 2

Hi,
I’m trying to sustitute and automate an old Carrier fancoil HVAC system that controls a 40DMC01 unit. The options it gave were NTC - Carrier Room Controller( CEPL130394-01 ) or WTC IR Controller (all of them using Carrier Comfort Network propietary sistems)

The main options I’m considering are:

  1. Use an old IR controller to get all codes sent to the system
  2. Unplug the wall controller, feed it with 24v transformer and try using a Raspberry pi zero w using GPIO connecting it to the system to reproduce the codes
  3. Using an ESP32 connect the system to my HA and control it

Does anyone know if there is any solution/library/project for this machines/Controllers so i can get more info?

Thanks
