Control Installation Instructions

9

Status Display Menu

The Status Display Menu is displayed during normal 
thermostat controller operation. This menu 
continuously scrolls through the following parameters:

Room Temperature

System Mode

Schedule Status (Occupied/Unoccupied/Override)

Applicable Alarms – The backlight lights up as an 
alarm condition is displayed.

Note:

An option is available within the Installer 

Configuration Menu to lock out the scrolling display and 
show only the 

Room Temperature

 parameter.

Configuring the TEC2145-4 Thermostat 
Controller

The TEC2145-4 Thermostat Controller comes from the 
factory with default settings for all configurable 
parameters. The default settings are shown in Table 4. 
To reconfigure the parameters via the thermostat 
controller, follow the steps in this section.

1.

To access the Installer Configuration Menu, press 
and hold the 

OVERRIDE

 key for approximately 

8 seconds.

Note:

If the 

Password

 parameter is configured, 

Password 0 appears on the thermostat controller 
display indicating that the configured password is 
required to proceed. Use the 

UP/DOWN

 arrow 

keys to indicate the configured password, then 
press the 

MODE

 key to proceed through the 

Installer Configuration Menu parameters.

2.

Once the Installer Configuration Menu begins, 
press and release the 

OVERRIDE

 key to scroll 

through the parameters listed in Table 4.

3.

When the desired parameter is displayed, use the 

UP/DOWN

 arrow keys to choose the desired 

selection option.

4.

Press and release the 

OVERRIDE

 key to continue 

scrolling through the parameters.

Note:

Pressing the 

FAN

 key during configuration 

restarts the list of displayed parameters at the first 
parameter listed in Table 4.

When the thermostat controller is in the Installer 
Configuration Menu and left unattended for 
approximately 8 seconds, the thermostat controller 
reverts to the Status Display Menu.

Configuring Inputs BI1, BI2, and UI3

When BI1 and BI2 are configured for an alarm 
condition, an alarm condition is displayed locally when 
the input is closed. An alarm message is included on 
the scrolling Status Display Menu and when the 
message is displayed, the backlight momentarily 
lights up.

The UI3 input provides changeover of hot/cold water 
switching, or supply air temperature monitoring at the 
thermostat controller.

Each input can be configured to the Selection Options 
included in Table 4. 

Configuring the Sequence of Operation 
(SeqOpera)

Choose the appropriate sequence of operation. The 
modes presented are user-dependent on the sequence 
of operation selected. For applications using a 
changeover sensor, choose the selection option 

(0): Cooling Only

. Changeover occurs between 

Cooling Only

 and 

Heating Only

. See Table 3 for 

selection options, and Figure 7 through Figure 10 for 
sequence of operation examples.
