Compatibility with DH18ZA1

[mrbluebrett]

Hi, i have a samsung duct AC model DH18ZA1, but it’s old and I’m not quite sure about compatibility with this project.

In the schematics i see the F1, F2, V1, V2, but with labels I think they are not the same thing. See them here:

The remote control is attached to R1, R2, R3… and Fs and Vs are for other things…

i also attach a picture of the remote (KR-H50110) if that helps:

Any help in making this model controllable with wifi module would be great.
Thanks in advance.

Hi, its pretty hard to say if this device will work or not. I am not a hardware guy. The cheapest option would be to buy an USB to RS-485 device and try to capture some traffic. Than we can see if this old device also uses the non NASA protocol. If not, it will be difficult.
