You could do that with a PLC (Programmable Logic Controller). They're quite costly, but by just reading its manual, you'll learn very quickly. I actually use PLC's in my trade (Im an electrician), so Im fairly knowledgable on them. Another way is using timers and contactors. You'll need two 8 pin (3 contact, plus coil) timers, plus 4 contactors, wire, etc. Contact me if you need more advice!
