Normally the pump would be activated by your controller. When you sprinkler schedule starts, your pump will start. When you turned on your system did you start the zones from your controller, or manually from the zone valves?
Since most of us haven't been to your home, I might suggest that for this time, you get the Irrigation Contractor that installed the system in to start up for the year. This way you will be able to watch him and be able to ask your questions.
Someone is still going to have to come in to test your backflow prevention assembly.
