I received an OpenSprinkler v3 (for my dad) a while ago. It came with an additional fuse, and instructions for wiring up the fuse on a small piece of paper. I seem to have lost that piece of paper.
May I please suggest that the installation instructions downloadable from your website be updated to included the instructions for wiring up that additional fuse?
Thanks for bringing this up. Yes it should be included in the user manual and I will add that shortly. It’s a fuse for the COM line, you can connect it between the COM terminal and your COM wire. It’s not entirely necessary but does provide some protection against shorted solenoid and mis-wiring of solenoids.
