Rain Bird System Short Cycling: Clarifying Symptoms for Diagnosis

Zones Set for 10 Min but Run 2 Min, Stop, Restart

Need clarification:

• Does each zone run 2 min then next zone runs 2 min?
• Or does zone 1 run 2 min, stop, then zone 1 runs again?
• Does it start at the scheduled time or randomly?
• What is the exact Rain Bird model number?

With these details, a precise diagnosis can be given.
