As long as you have 1vac line going in and a gauge linked to the system that's all you need to start with it can be VERY basic and will work 99% as well as an all singing all dancing pc controlled clave
All depends what you want to do and how much you want to spend
I want 3 or 4 vac line, at this moment I have tri-angle pipe line at oven but IMO it was't good idea. I mean 3 gauges.
