My landscaper was out today and in the process of diagnosing why one of the valves wasn’t working he managed to fry additional stations.
It appears I have three triacs that are blown. See uploaded image. From reading the forums I suspect that there’s no short protection for a station. I’m a beginner when it comes to sorting out parts but I’m ok with the soldering end of things.
– What part # do I need to replace these?
– What can I do to prevent this in the future?
I have OpenSprinkler RasPi 1.2
