Navigating the Human Interface Screens
In the following sections the user will be presented with a number of screens and submenus that follow the selection of
a main menu key entry (Status, Setpoints, Diagnostics, Setup, Configuration, Service Mode and Custom). When
a submenu is presented, it may be accessed by pressing the Enter key or, skipped entirely by pressing the Next key. Upon
entering a menu, or submenu, the user will navigate through the desired selections by pressing the Next and Previous
keys. The most probable keystroke would be to press Next to cycle forward through the screens as shown in these
sections, but pressing the Previous key may be desirable to review previous screens or to quickly navigate to the end
of a menu.
Once the user has navigated to a desired selection, the + (Plus) and - (Minus) keys will be pressed to cycle through the
selection range of the menu item. The range of each item selected is dependent upon the item and is listed for each screen
in the following sections. For instance, if the user has selected a Configuration item typical choices displayed with each
+ (Plus) or - (Minus) keystroke may be Installed or Not Installed. If a Setup menu were accessed a choice may be Enabled
or Disabled. Temperature Setpoints will typically cycle through their range one degree at a time, and so on. Similar to
pressing the Previous key above, pressing the - (Minus) key to decrement through the range may provide quick access
to the desired value.
Once a change has been made to the desired menu item the user will press the Enter key to accept the change, or press
the Cancel key to ignore the modification and return the displayed item to its original value.
