Programming/Operating the TEC2102-3
Thermostat
Once the thermostat is configured via the Installer
Configuration Menu, its operating parameters can be
programmed via the Main User Menu. Access this
menu by pressing the MENU key during normal
thermostat operation. The Main User Menu contains
the basic operating features of the thermostat.
The Main User Menu also uses Auto Help, which is
displayed automatically in the menu when there is a
pause in programming activity. To exit Auto Help,
continue with the programming selection. When the
thermostat is in the Main User Menu and is left
unattended for 45 seconds, the menu reverts to the
Status Display Menu.
Enabling Override Schedule
Note: Enabling Override Schedule only appears when
in the Unoccupied Mode.
The override schedule prompt only appears when the
thermostat is in the unoccupied state. This menu
selection gives the user the option of overriding the
unoccupied setpoints with the occupied setpoints for
the amount of time specified under the TOccTime
parameter. See the Configuring the TEC2102-3
Thermostat section.
Note: If one of the digital inputs is configured to
operate as a remote override contact, this menu is
disabled.
