ok I will replay to this myself.
I closed my eyes blind and connected 24VAC valved to OpenSprinkler 2.3 DC controller powered from 7.5V
– Common wire from valves to Common plug on OpenSprinkler.
– and each valve control wire to OpenSprinkler 2.3 DC control port.
and I run test program to open and close Valve and………. it just worked.
Valves are opening and closing no problem. 🙂
