Operation

Programming/Operating the TEC2101-3 
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.

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

 key to resume the programmed 

schedule.

The thermostat returns to the Status Display Menu.

Entering Permanent Temperature Setpoints

The first prompt appearing in the Main User Menu of 
the thermostat when in the occupied state is to set the 
permanent temperature setpoint.

To enter the permanent heating and cooling setpoints 
for the Occupied and Unoccupied Modes, follow the
