What is error code H4
Hi don the error code is a system overload. There are a lot of things that could be causing this temperature short circuit. Inwould take the cover of the unit and see if you can visually see any maybe dust or debri on any condenser coils or fans. If you can't figure it out call an expert.
Here is a link to the manual for your system

I keep getting a p5
I have a 3 unit split.
I found out that you can not have one unit set to warm and the other to cold. The compressor doesn't understand it.
Cycle off on and quickly re mode to Cool .
Do it to each unit and you will get it to stay on and then you can adjust.
Took a while for me but it did stay on after switching Mode at startup
