What kind of power supply are you using? It must be a 24VAC – NOT 24VDC!!

Whenever all the valves open immediately after switching on, it seems to be the wrong power supply, because the triacs used need a zero crossing in order to switch, which only works with alternating voltage.

Immediately disconnect the OpenSprinkler from the (wrong) power supply, as the high current flow dangerously overloads the OpenSprinkler and solenoid valves.
