Watering System Mystery

I recently moved into a house and am not sure what to make of the Irrigation System. On the inspection report it listed 6 zones and the timer is mechanical. So I purchased a digital timer and traced the wires back to the valve and found only one. After playing with it for a while I discovered that the only way to water another zone is to turn on the sprinkler and then turn it off for 10 seconds and then turn it back on and it would work on another zone.

Does anyone have any idea what this is called or what my options are for updating the controls?
