Help: Does it support this model from China?

[treblam]

My Daikin air conditioner is from the VRV-N series, and the model is RYZQ4AAVN. I couldn’t find any information about the available ports on the indoor unit. However, I have taken some pictures of it. Could you please help me identify whether it has the ports supported by this project? Thank you in advance!

As shown in the picture, there is a 5 pin plug in the corner of the unit, but I don't know the specific function of it.

If it has an S21 port it probably works.

[treblam]

Yes, I know this project supports S21, but is there any way to identify whether the port I marked with the red box is S21, X50A, or CN_WIRED?

[revk]

Well usually it says S21 or X50A by a connector

[treblam]

It's hard to capture from that angle, I'll try to figure it out. thanks!

@treblam Do you have any progress or updates? I also have 4 AC units and want to know if they can work

[treblam]

Yes, a little bit progress.
First, the bad news is my air conditioner is not supported by this project, because my indoor unit (FQDP56BVC) doesn't have the ports supported by this project.
Next, the good news is the P1P2MQTT project(https://github.com/Arnold-n/P1P2MQTT) supports this indoor unit, but you have to buy one P1P2MQTT bridge for each of your indoor unit.
