Main User MenuUse the Main User Menu to access and change the basic operating parameters ofthe rooftop controller. During normal rooftop controller operation, press theMENU key once to access the Main User Menu. This menu is most commonlyused by the zone occupant and includes the following parameters:• Schedule Override/Cancel Override• System Mode• Set Schedule• Set ClockThe Main User Menu uses Auto Help. Auto Help appears automatically in theMain User Menu when programming activity pauses.Configuring the TEC2647Z-2 or TEC2647Z-2+PIR Zone ControllerThe zone controller comes from the factory with default settings for allconfigurable parameters. The default settings are shown in Table 2. Access theInstaller Configuration Menu on the zone controller to reconfigure the parameters.To access the Installer Configuration Menu, press and hold the OVERRIDE keyfor approximately 8 seconds.
