Hi deaklin.
I suspect you know far more about these than me.
However I have to dispute the 2 comps statement as there is a 3 comp per circuit version.
In fact reading my own attachment it would appear the 160 is indeed 2 +2 comps?
That does not mean that Vanpu has such of course.

Some RA's have 4 comps per circuit I would need full model to be sure though

Hi everybody,
Thank you for help me.
I'm sorry. It have 2 circuit unit: circuit A and circuit B. But each circuit have 2 compressor.
I think it have problem at the Pro – Dialog control.
Tomorrow, The chiller only run 1 compressor.
Today, I tried again. First, the chiller run have 2 compressor then auto shutdown.When I try again its have error then I reset this error and run the chiller again. Its run good (have 4 compressor run)

Hi vanphu.
The fault you reset may be the clue to what is wrong, what was it?
