The case is one thing. It is indeed not ready yet.
It does support 4 separate contacts (Green, White, Yellow, Red) @ 24V AC with 3 relays but it also requires mains supply too (100-240V AC)
Another thing is that the LCD does not allow to turn the fan and/or heating/AC separately so you will need to customise it the way you want it yourself (with any help from me in terms of questions).
if you are happy with that read the full page of the non-US model in the shop to inform yourself on the features and bugs.
I just want you to be sure you know what to expect from what you are buying.
