I have 5 zones and when I try to run just one zone, zone 1 comes on with it. When I don't turn on any zones, zone 1 still turns on. This system has worked fine for years until this season. Any thoughts ar appreciated. Glenn
if zone 1 is on all the time it sound like the valve has been manualy
opened or the diafram in side the valve is stuck tap on valve
if water is on and zone-1 comes on when you put control-box to auto
it sounds like control-box malfunction put zone-1 wire on a different
zone number to determine
