Menu Screens
Various menus are shown in the controller display. Each menu screen shows specific
information, in some cases menus are only to view status of the unit, in some cases for
checking alarms, and in some cases they are used to set setpoint values that can be
changed.
The menus are arranged in a matrix of screens across a top horizontal row. Some of these
top-level screens have sub-screens located under them. The content of each screen and its
location in the matrix are shown in Figure 8. A description of each menu begins on page
55.
The arrow keys on the controller are used to navigate through the menus. The keys are also
used to change numerical setpoint values contained in certain menus.

menus are self-explanatory. A Setpoint menu allows selection of whether the unit has a
