The TEC2202-3 non-programmable and
TEC2262-3 programmable thermostats are
L
ONWORKS® networked devices that provide control of
heat pump equipment. The technologically advanced
TEC22x2-3 thermostats feature a Building Automation
System (BAS) L
ONWORKS network communication
capability that enables remote monitoring and
programmability for efficient space temperature control.
IMPORTANT: The TEC22x2-3 thermostat is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices such as
supervisory or alarm systems or safety or limit
controls intended to warn of, or protect against,
failure or malfunction of the thermostat.
North American Emissions Compliance
United States
This equipment has been tested and found to comply
with the limits for a Class A digital device pursuant to
Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful
interference when this equipment is operated in a
commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the
instruction manual, may cause harmful interference to
radio communications. Operation of this equipm ent in a
residential area is likely to cause harmful interference,
in which case the user will be required to correct the
interference at his/her own expense.

Installation
Location Considerations
Locate the TEC22x2-3 thermostat:
•on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature
•away from direct sunlight, radiant heat, outside
walls, behind doors, air discharge grills, stairwells,
or outside doors
•away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
Note: Allow for vertical air circulation to the
TEC22x2-3 thermostat.
To install the thermostat:
1. Use a Phillips-head screwdriver to remove the
security screw on the bottom of the thermostat
cover.
2. Pull the bottom edge of the thermostat cover and
open the thermostat as illustrated in Figure 1.
Canada
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
3. Carefully pull the locking tabs on the right side of
the thermostat mounting base and unlock the
Printed Circuit Board (PCB). Open the PCB to the
left as illustrated in Figure 2.

4. Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the hole in the
thermostat mounting base.
5. Align the thermostat mounting base on the wall and
use the base as a template to mark the two
mounting hole locations.
Note: Be sure to position the thermostat mounting
base so that the arrow on the base points upward
to indicate the top of the thermostat.
6. Drill a 3/16 in. (5 mm) hole at each of the two
marked locations and tap nylon anchors (include d
with the thermostat) flush to the wall surface.
7. Position the thermostat mounting base on the wall
and use the two mounting screws (included with
the thermostat) to secure the base to the surface
as illustrated in Figure 3.
Note: Be careful not to overtighten the mounting
screws.
8. Swing the PCB back to the right and carefully snap
it into the locking tabs on the thermostat mounting
base.
9. Pull the pull tabs on each of the connectors and
remove the screw terminal blocks as illustrated in

To wire the thermostat:
1. Strip the ends of each wire 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Figure 5 and Figure 7.

(LIT-1162150).
2. Carefully push any excess wire back into the wall.
Seal the hole in the wall with fireproof material to
prevent drafts from affecting the ambient
temperature readings.
3. Reinsert the screw terminal blocks onto the PCB.
4. Reattach the L
ONWORKS communication wires to

Backlit Liquid Crystal Display (LCD)
The TEC22x2-3 thermostat includes a 2-line,
8-character backlit display. Low-level backlighting is
present during normal operation, and it brightens wh en
any user interface key is pressed. The backlight returns
to low level when the thermostat is left unattended for
45 seconds.
Light-Emitting Diodes (LEDs)
Three LEDs are included to indicate the fan status, call
for heat, or call for cooling:
•The FAN LED is on when the fan is on.
•The AUX HEAT LED is on when auxiliary heat is
on.
•The HEAT PUMP LED is on when the heat pump
compressor is on.
Programming Overview
There are three menus used to view, program, and
configure the TEC22x2-3 thermostat.
The Status Display Menu is displayed during normal
thermostat operation. This menu continuously scrolls
through the following parameters:
•Room Temperature
•Clock (TEC2262-3 only)
•System Mode
•Occupancy Status – Occupied/Unoccupied/
Override
•Outdoor Temperature – An outdoor air temperature
sensor must be connected.
•Applicable Alarms – The backlight lights up as an
alarm condition is displayed.
Note: Press the YES/SCROLL key to temporarily stop
this menu from scrolling.
The Main User Menu is used to access and change
the basic operating parameters of the thermostat.
Access this menu by pressing the MENU key during
normal thermostat operation.
-access the Installer Configuration Menu or to
exit the menu (See the Configuring the TEC22x2-3 Thermostat section.)

configuration parameters and to activate a setpoint
adjustment.
The TEC22x2-3 thermostat comes from the factory
with default settings for all configurable parameters.
The default settings are shown in Table 2. To
reconfigure the parameters via the thermostat, follow
the steps in this section.
1. To access the Installer Configuration Menu, press
and hold the MENU key for approximately
8 seconds.
2. Once the Installer Configuration Menu begins,
press the NO key to scroll through the parameters
listed in Table 2.
3. When the desired parameter is displayed, use the
YES key to choose the desired selection option.
4. Press the YES key and then the NO key to
continue scrolling through the parameters.
To exit the Installer Configuration Menu any time, press
the MENU key, and at the exit prompt, press the YES
key. To pass over a parameter without changing it,
press the NO key.
When the thermostat is in the Installer Configuration
Menu and left unattended for approximate ly 8 seconds,
the thermostat reverts to the Status Display Menu.
For additional information on commissioning and
configuring thermostats, adding thermostats to a
Network Automation Engine (NAE), thermostat
mapping, and remote thermostat commanding, refer to
Configuring the Thermostat’s Neuron®
Identification
Press and hold the UP/DOWN arrow keys
simultaneously for 5 seconds to broadcast the
thermostat’s Neuron Identification on the L
ONWORKS
network.
If the cover is removed, you can see a green LED
under the LON board flash when the thermostat
broadcasts the Neuron ID. The Neuron ID is on a label
on the Echelon® chip.
You cannot send the Neuron ID while in the Installer
Configuration menu.
Configuring Inputs DI1 and DI2
When DI1 and DI2 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.

week. The schedule-setting menu reflects either a
two- or a four-event schedule per day, based on what
was selected in the 2/4event parameter during the
configuration process. If the schedule-setting menu
does not reflect a two-event schedule, select two
events in the 2/4event parameter of the Installer
Configuration Menu.
When changing the time, press the UP/DOWN arrow
keys once to change the time in 1-minute increments;
press and hold down the keys to change the time in
30-minute increments.
