Practical setup tips
To maximize results, pair this kit with proper circuit protection, verify IN.Therm sensor placement, and confirm your spa’s existing ozone (Oz) and circulation configurations align with the new wiring map. If you’re replacing an older system, document your current P1/P2/Cp/Bl/Oz/L/Acc connections before installation so you can mirror the exact layout on the new unit. Regular maintenance—checking seals, keeping the control enclosure dry, and cleaning filters—helps extend the life of both the control system and the spa components it manages.
