The controller shows 10 programed zones... I found 5 valves... I thought I had to have 1 valve for every zone, but I can only find 5 valves... Can 1 valve control 2 zones?... zone 5 is not working but zone 6 is... I swapped valves #1 to #3 and zone 5 worked but zone 3 stayed on with each zone only changing pressure depending on what other zone was on at the same time... zone 6 did not work... Very Confused
