Your spa is set to normally allow you to raise the Set Temperature only to 104 °F
However, by using a special procedure, you can raise the Set Temperature to 105 °F or even 106 °F
First, make sure the Set Temperature is already at 104 °F (40.0 °C). If it isnt:
Raise the Set Temperature to 104 °F (40.0 °C).
Confirm (with the Navigation* button) or wait until the Set Temperature times out.
Once the Set Temperature is at 104 °F (40.0 °C):
Press any temperature button, and while the Set Temperature is displayed (flashing):
1) Press and hold the Navigation* button, then
2) Press the Warm or Temp button once to raise the Set Temperature to 105 °F (40.5 °C) or twice to raise it to 106 °F (41.0 °C).
If the Set Temperature is either 105 °F (40.5 °C) or 106 °F (41.0 °C) and you simply press any temperature button while the Set
Temperature is flashing, the Set Temperature will jump to 104 °F (40.0 °C).
If you want to raise the Set Temperature from 105 °F to 106 °F, you must:
Press any temperature button once to display the current Set Temperature.
While the Set Temperature is flashing:
1) Press and hold the Navigation* button.
2) Press the Warm or Temp button (again) to raise the Set Temperature by that one extra step.
**You cannot lower the Set Temperature directly from 106 °F to 105 °F. You have to repeat the procedure above.
**Once an Over-Range Temperature is set, the water temperature display shows o instead of F or C after the temperature.
If the spa is powered down with a Set Temperature of 105 °F or 106 °F,
when it powers back up it will have a Set Temperature of 104 °F.
**The Navigation button is whichever button you use to navigate through the menus on this panel.
**On many panels its the Light button, but on certain panels it may be a button dedicated to menu navigation
