On all Dimension One Spas, when the water temperature is 1˚ below the
set temperature the heater will turn on and remain on until the water
temperature rises to 1˚ above the set temperature. On models that do
not have circulation pumps (Aurora, Interlude, Arena, Triad and Quadra
without the CrystalZone Water Management System) the low speed
pump will turn on during the heating cycle.
On models with Ultra Pure (Chairman II, Chairman, Diplomat,
Californian, Nautilus and Aurora II) and models with the Crystal Zone
Water Management System: To prevent the spa from overheating, the
circulation pump turns off when the water temperature rises 2˚ above the
set temperature. When the water temperature cools down to the set
temperature, the circulation pump will turn on.
NOTE: The circulation pump will run for short periods when the water
temperature is 2˚ above set temperature to provide optimum operation.
