I managed to get a different solenoid valve today – from the same company. Bit of a limited supply here. It’s exhibiting the exact same thing, once the station/circuit is on at 24v ac it won’t go down to 0 and won’t shut off.
It does it perfectly when the station has nothing connected so I doubt it’s an issue with the software. Hardware seems unlikely. Double checked the wiring nothing seems wrong. Have I missed a simple instruction somewhere? If there’s something obviously wrong with the pic attached please point it out 😀
Picture attached – new solenoid on the left (station 4), original on the right (station 2). I used both COM ports because it was easier and they’re wired to the same circuit in the instructions.
