Before you buy — quick checklist

  • Confirm your existing control system model number matches CS6P59Y-US before ordering
  • Verify your spa is equipped with a HydroQuip Y Series slide heater configuration
  • Check that your current topside is the In.K200 model — this system includes that specific topside
  • Note your supply voltage to ensure compatibility with this control system
  • Determine whether your HH or OH fault is being caused by the control system versus a failed sensor or blocked flow — replace sensors separately if needed
