I've installed the unit controllers and main controllers and it's all up and running.

I have done a few quick tests and (certainly with the current temperature here of 28C) it looks like I'm only going to be able to run 2 of the 3 compressors.

The problem is when the 3rd compressor kicks in the gas pressure goes up quite dramatically and I'm sure it's not safe. It also sounds like the compressor(s) start struggling to run. With just the main unit and one of the twin unit compressors running all seems fine.

When the second compressor kicks in there is definitely a good increase in heat output.

So it's now a waiting game until it cools down and I need to start heating the house - probably towards the end of October (I switched on the heating the 27th last year).
