Smartline 1600: Just keeps recyling same program

I have a Smartline 1600 that is set, under program A, for 8 zones, each 30 minutes, all starting at 3:00 am, stacked. It starts at zone 1, cycling to zone 8. Should be done at 7am, of course, but the program keeps recycling, going back to 1, 2, etc. What am I doing wrong? I cleared all the programming using advanced features. Programs B, C, and D are not programmed. But it keeps doing it over and over again. Help!!

You likely have additional starts programmed. You might have best luck by performing a reset, following the mfr instructions to do so, and then reprogramming the controller.

Just remember only one single start time is needed for a complete cycle of watering.

Stuck

Have imperial controller with brass valves (6 zones). Zone three was not coming on so I replaced with a Rainbird inline valve. Then I could not get that valve to shut regardless of what zone controller was on - after bleeding got zone to shut but cannot get any others to activate on their respective zones. Now just puzzled???

there was probably nothing wrong with the valve you replaced. You should try connecting the zone 3 wire to another (unused) controller station. This is a problem, of course, if you are already using all 6 zones of the controller.

Try resplicing the ground wire.

there is a zone-failure mode in old electro-mechanical controllers, due to poor continuity in the wafer-switch assembly - it might be remedied by cleaning the contacts, but some of them are passing line voltage, so fiddlers beware

Ok, Don't double check your wiring.

When encountering non-opening zones with these old controllers, it pays to check the controller output first. Sometimes the non-opening is only temporary, as the 'timing wheel' slowly turns, and the wafer switch contacts finally close.
