Can I replace a Rain Bird or Toro controller with a Hunter controller?

Yes, in most cases. Controllers are low-voltage (typically 24 VAC) and connect to existing valve wires. Label every zone wire before disconnecting the old timer, match common (COM) and station terminals, and verify transformer VA for the number of valves that may fire. Solenoid brand usually does not require matching the controller brand.
