Backlit Liquid Crystal Display (LCD)
The thermostat controller includes a 2-line, 8-character
backlit display. Low-level backlighting is present during
normal operation, and it brightens when any user
interface key is pressed. The backlight returns to low
level when the thermostat controller is left unattended
for 45 seconds.

The Status Display Menu displays during normal
operation. This menu scrolls through several
parameters:
•

Room Temperature and Humidity (TEC2036-2,
TEC2036H-2, TEC2056-2, and TEC2056H-2
models)
•

Configuring the Thermostat Controller
The thermostat controller comes from the factory with
default settings for all configurable parameters. The
default settings are shown in Table 6. To reconfigure
the parameters, follow the steps in this section.
To access the Installer Configuration Menu, press and
hold the center key for approximately 8 seconds. Once
the Installer Configuration Menu begins, release and
press the center key to scroll through the parameters
listed in Table 6. When the desired parameter displays,
use the UP/DOWN arrow keys to choose the desired
selection option. Then press and release the center
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 6.
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 displays locally when the
input closes. 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 6.
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 two-pipe applications using a
changeover sensor, choose the selection option
(0): Cooling Only. Changeover occurs between
Cooling Only and Heating Only. See Figure 13
through Figure 18 for sequence of operation
examples.
