I was so excited to get our system running. Turned it on (1st time in a couple yrs to run some diagnostics). The 1st station came on ( about 4 or 5 rotating heads- shooting like 5ft) cool... The controller switched stations after 10 min to zone two. Went back to zone one and it wouldn't pressure up. I later noticed that all these heads are on low on the opposite side of the house. These have good pressure, but will not shut off. We disconnected the wires to all but station 1, and these only shut...
