Wind free: how to pair one remote to only one split

[entropy70]

Hi, I recently purchased and set up a wind free airconditioning system with 1 external machine and 3 split.

One in the living room, one in my studio and one in the bedroom. Unfortunately my flat is small (80sq mt) and therefore when I use one remote to turn on the living room split...the one in the bedroom turns on instead. Same for the other ones, I am looking for a safe and proven way to pair one remote only to the living room split, another remote to the bedroom split and the last remote to my studio split.

I have searched high and low and couldn't find anything 😞 I can't believe such an advanced tech doesn't allow this simple feature.

thanks
