Button and Navigating Menus
The VSP
Elite
has three buttons.
• The SET button function varies. When the Default Screen is displayed, pressing the SET Button views the MENU. When in the
Menus and settings, the SET Button accepts the selected entry or setting value.
• When in the menus, pressing the Up and Down buttons will scroll through the menu options. They can be used to change the
setting of a specific function. i.e., change the Set Point, Differential, or System Trim. In addition, when in the default screen, the
Up and Down buttons will display the outdoor temperature and Outdoor Cutoff when no return sensor is available, or the outdoor
temperature and the return temperature when an active return sensor is connected.
• At the end of every operation menu there is a
<Back>
option that allows the user to go back one menu level. If the SET Button
was held down for three seconds on the
<Back>
option, the display will go back to the default screen.
