Operation

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.

To override the unoccupied state while in the Main User 
Menu:

1.

Press the 

NO

 key to all prompts until the Override 

Schedule prompt appears. If the thermostat is in 
the unoccupied state, this is the first prompt.

2.

Press the 

YES

 key to enable the temporary 

override. The thermostat returns to the Status 
Display Menu.

When scrolling through the Status Display Menu, 
Override now appears for the occupancy status 
parameter.

Resuming the Programmed Schedule

This menu only appears when the thermostat is in the 
unoccupied override mode.

To resume the schedule while in the Main User Menu:

1.

Press the 

NO

 key to all prompts until the Cancel 

ovrd Y/N prompt appears. If the thermostat is in the 
unoccupied override state, this is the first prompt.

2.

Press the 

YES

 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.

Comp/aux

Sets the mode of interaction 
between the heat pump and the 
auxiliary heat.
Default:

 off

(on)

 – in the heating mode only: If the heat pump is not able to 

satisfy the heating setpoint, the auxiliary heat is energized and the 
heat pump is shut off. This typically applies when the air handler 
heat pump coil is installed after the auxiliary heat. There is a 
2-minute delay to restart the heat pump after the auxiliary heat is 
shut down.

(off) 

– in the heating mode only: If the heat pump is not able to 

satisfy the heating setpoint, the auxiliary heat is energized at the 
same time as the heat pump stage. This typically applies when the 
air handler heat pump coil is installed before the auxiliary heat (all 
electric systems).

1.

When adjusting the numeric value, press the 

UP

 or 

DOWN

 arrow key to change the value by single increments; press and 

hold the 

UP

 or 

DOWN

 arrow key to change the numeric value in increments of ten.

2.

When adjusting the temperature, press the 

UP

 or 

DOWN

 arrow key to change the value in 0.5F°/0.5C° increments; press 

and hold the 

UP

 or 

DOWN

 arrow key to change the value in 5.0F°/5.0C° increments.

3.

When the outdoor air sensor is not connected or it has a short, the thermostat bypasses heating lockout, cooling lockout, 
high balance point, and low balance point. Emergency mode bypasses heating lockout and permits auxiliary heating 
whenever a heating demand occurs.
