  • If your spa is a Tiger River or Limelight Spa prior to 2012.5, please be aware that the Control Panel for your spa is obsolete and no longer available from the manufacturer. This means, if your control panel ends up failing/going bad, you will need to upgrade to the newer IQ 2020 Eagle (76836 Control Box and 76845 Control Panel) system. We are encouraging customers in this situation to upgrade to the newer IQ 2020 Eagle System to avoid possible extra costs in the future.

Use the "Check Serial Number Compatibility" widget below to confirm that this control box is compatible with your spa model.
