SET THE TEMPERATURE
In this example we will set the Set Temperature to 102°F
(39°C).
• Press the water temperature display button (A) to make
the temperature menu appear (B). The center box with
the arrow (C) indicates the current Set Temperature.
• If 102 (39) is already showing, but just not centered
(D), touch it to center it (E).
• If 102 (39) is not showing (B), swipe the temperature
menu until 102 (39) appears (D).
• If 102 (39) appears after swiping but does not stop in
the center box (D), press 102 (39). Pressing 102 (39)
makes it shift to the center box (E).
• Press the water temperature display (A) to make the
temperature menu disappear. The Set Temperature is
now 102 (39).
How do I know when the heater is On?

red (A) when the heater is On. The Heater
Status icon appears in the top left corner of the Spa screen
when the heater is On.
