The controlling box was installed, sensors attached, fans and pumps connected, successful (or less 🙂 ) tests were performed, 220V fed into a hero (survivor) 12V fan… but we eventually got there. Surprisingly enough, everything is now working according to plans. Thank you Niall O’Brien for helping with the installation, and good luck with understanding the complicated, weird logic of my brain that eventually translated into controlling some “simple switches”, as you put it.
