Can you discribe this in more detail?
Was the suction pipe linked as well?

[philjd26]

hi,no suctions connected it was just liquid line linking each outdoor...

It's just a multistage capacity control method.

There is one invertor driven compressor and however many fixed speed compressors that are required to provide the full load.

You could say that it a system with XX unloaders ;)

as far as i can see liquid is present at the indoor unit, if cooling it draws liquid and if heating produces liquid....maybe it just time for the pub:)
