Dear customer,

Yes, you can add a second Sprite or Spark controller as you told.

Key Tip: Ensure the watering schedules of both controllers do not overlap. Running both simultaneously could cause electrical back-feed issues to your pump relay. Alternatively, if a faucet is available, our Pixie timers can expand your system wirelessly.

For a safe wiring diagram specific to your bore system, please email us at support@netrohome.com.

Best regards,

Candice Wang
