Zones coming on when water supply is turned on and system is off

I have a new home that came with a sprinkler system. When I turn the water from the main valve the two zones on the sides of the house come on even though the system is off. They will stay on when I run the Test or try to have other zones running. What would cause a zone to run at all times
