Why do you have it set to go off at different times? They should all run in sequence on the same night. (when zone 1 shuts down, zone 2 should start and so on). Most people use "program 1" "setting a". All the others should be "off"
The only reason to have other settings "on" would be if you have a new area of grass or a garden or a newly planted tree that should get extra watering more than once a week.
