Overview
About this task:
Figure 16 shows the thermostat controller home screen
in both the light and dark themes. You can customize
it to show or hide various elements from the occupant.
See Table 6 for a listing of the touchscreen icons and
Table 14 to identify the home screen settings under the
Display Settings. When screen customization is used in
conjunction with a passcode, the building owner can
control which options the occupant can access and adjust.
Important: If lockout levels are used, some icons
are hidden. Table 7 provides details of these levels.
