Thermostat Controller User Interface Keys

The user interface consists of keys on the front cover
(Figure 12). The function of each key is as follows:
• MODE key toggles among the system modes
available, as defined by selecting the appropriate
operation sequence in the Installer Configuration
Menu (Off, Heat, Cool, Auto).
• FAN key toggles among the fan modes available,
as defined by selecting the appropriate fan menu
options defined in the Installer Configuration Menu
(Low, Med, High, Auto).
• OVERRIDE key (commercial models) overrides
the unoccupied mode to occupied at the local user
interface for the specified TOccTime. (TOccTime is
defined by selecting the appropriate time period in
the Installer Configuration Menu.)
