A spa device is a pump, blower, light, etc. Follow these steps to run spa devices:

Press the Spa button (A) to view the Spa screen.
Press these buttons (B) to run spa devices. Some
devices may only turn On and Off, while other
devices may have multiple speeds/states. Your spa
configuration determines the number of buttons and
the function of the buttons in the Spa screen. One Spa
screen displays six buttons, maximum. If more than six
buttons exists, a navigation button appears (D). Press
the navigation button (D), or swipe, to view the next Spa
screen. Press the Back button (C) to navigate to the
Main screen. 

If the Jets are left running, they will turn off after a time-out period. 

If the Spa has a circulation pump, a circulation pump icon will appear in the Spa screen to indicate its activity only (the icon is not a functioning button). The circulation pump can be controlled with a button during Priming mode (view page 26). 

If the spa does not have a circulation pump, then Jets 1 may turn On automatically at times. In these cases, pressing the Jets 1 button will just change speeds, but will not turn Off Jets 1.
