What I did last night was I programmed timers 1, 2, 3 and saved it and then set it to program logic G1& G2 but then when it came time to set S1 to them there was nothing in the drop down for it. so thats where im stuck now. And how would I do pump 2 (S2) with that? Would I use G3 & G4 with the next 3 timers?
