It appears to be a wiring problem, so the question is how to isolate the problem between your Zones 1 & 5. I do irrigation as a small business and have encountered a prospective customer with a 13 Zone Rachio Controller that is running two stations at the same time. I think that in his frustration he ordered a new Hunter controller to which I advised him not to install it until he solves the 2-station problem. So, this is what I would do. 1. First, determine if it is in fact a wiring problem. 2. Go to the place where all the wires are bundled and fished into your garage where your controller is located. 3. Isolate Zone 5 and cut the station wire. You will need a Pro-48 to isolate which wire it is if the are all the same color. Then test your Controller. If both Zone 1 and 5 activate, then your problem is a wire problem shared by Zone 1 to Zone 5. If Zone 1 is the only one operating then it is Zone 5 that shares wire with Zone 1. To confirm this, reconnect your Zone 5 and cut the Zone 1 station hot wire outside at point of entry (you will need a Pro-48 to isolate the wire); run your zone 5; if only Zone 5 activates, then Zone 5 wire is not shared with Zone 1. Go to work and and find where those wires are being shared. The alternative is to splice a new wire Zone 1 entry point to house and run it all the way to Zone 1 valve box and wire to solenoid; cut the original wire. Just my thoughts on troubleshooting the problem. I plan to meet with him next week; he also has a pump, I can tell he is very frustrated. I will report my findings at a future note. Stay safe out there. Roy
