About this control pack

The HydroQuip Y Series Lo-Flo Control System CS6P52Y-US is a complete spa heater control platform designed for HydroQuip-equipped hot tubs using the Y series Lo-Flo system architecture.

At Bubbles Supply, we guarantee an exact fit for your HydroQuip system and ship same-day to get your spa running quickly. Every control system comes with our comprehensive 1-year warranty for complete peace of mind.

  • Confirm you have a Lo-Flo system architecture — this unit is NOT interchangeable with standard-flow HydroQuip control systems
  • Document all existing wiring connections with photos before disconnecting anything
  • Check that your topside control panel connector is compatible with this control system
  • Verify whether your spa uses any auxiliary equipment (blowers, ozone, etc.) that must be supported by the replacement control pack
