Question
Matt,
My Total Control?Series 15 stage Hardie is 10 years old. Lately I've had a problem with the first three stations all coming on at once and they remain on throughout the watering cycle. Even when one station is selected at a time! I抳e even discounted the culprits from the control box and re-arrange their location in the start cycle but they still come one when any station is selected. Would this be a wire fault or a controller box failure? Without a 搒hort?indication in the display area how would I check? Thanks in advance.

Answer
James,

It could be a wire short between 2 0r 3 wires but it work both ways. If wire #1 is turning on #6 then #6 will turn on #1. It doesn't sound like your having that problem.
I'd suggest looking at your valves. I think you have 3 bad ones. Some times they can remain closed when the system is off, then when a zone come on it lower the pressure and allows the bad one to open.
