Issued February 8, 2010

Applications

The TEC22x6(H)-4 and TEC22x6H-4+PIR Series
Thermostat Controllers are L
devices that provide control of two- or four-pipe fan
coils, cabinet unit heaters, or other equipment using
on/off, floating, or proportional 0 to 10 VDC control
input, dehumidification capability, and up to three
speeds of fan control. The TEC22x6H-4+PIR Series
Thermostat Controllers have occupancy sensing
capability built into the device. These devices maximize
up to 30% energy savings in high-energy usage light
commercial buildings, such as schools and hotels,
during occupied times by using additional standby
setpoints. See the Occupancy Sensor Operation –
TEC22x6H-4+PIR Series Thermostat Controllers
section for more information.

The technologically advanced TEC22x6(H)-4 and
TEC22x6H-4+PIR Series Thermostat Controllers
feature a Building Automation System (BAS)
L

ONWORKS network communication capability that

enables remote monitoring and programming for
efficient space temperature control. Specific models
are available to accommodate commercial and
hospitality applications.

The TEC22x6(H)-4 and TEC22x6H-4+PIR Series
Thermostat Controllers feature an intuitive User
Interface (UI) with backlit display that makes se tup and
operation quick and easy . Th e thermostat s also employ
a unique, Proportional-Integral (PI) time-proportioning
algorithm that virtually eliminates temperature offset
associated with traditional, differential-based
thermostats.

IMPORTANT: The TEC22x6(H)-4 and
TEC22x6H-4+PIR Series Thermostat Controllers
are intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat controller 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.

Thermostat Controllers.

To install the thermostat:

1. Use a Phillips-head screwdriver to remove the
security screw on the bottom of the thermostat
cover.

Note: Normally, the security screw is packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed
on the bottom of the cover.

2. Pull the bottom edge of the thermostat cover and
open the thermostat as illustrated in Figure 1.

Note: PIR models have a wiring connection
between the cover and the Printed Circuit Board
(PCB). This connection allows for proper wiring of
the occupancy sensor. Carefully remove the wiring
connection from the PCB by pulling up on the
connector block. Do not attempt to remove the

connector block by pulling on the wires

PCB
Locking

FIG:prnctbd

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.

6. Position the thermostat mounting base so that the
arrow on the base points upward to in dicate the top
of the thermostat.

3. Carefully pull the locking tabs on the right side of
the thermostat mounting base and unlock the PCB.
Open the PCB to the left as illustrated in Figure 2.

Note: If you need to install the thermostat on an
electrical junction box, use 2-1/2 x 4 in.
(63 x 101 mm) square boxes with mud ring covers,
and avoid smaller 1-1/2 x 4 in. (38 x 101 mm) or
3 x 2 in. (76 x 51 mm) square boxes. This
procedure ensures that you have enough space for
cabling and end-of-line devices, if needed.

Note: For surface-mount applications, use
durable mounting hardware such as Molly bolt
anchors that cannot be easily pulled out of the
mounting surface.

7. Secure the mounting base to the wall surface using
two mounting screws as illustrated in Figure 3.

Note: Be careful not to overtighten the mounting
screws.

For more details on wiring the L
refer to the L

ONWORKS Network Layout Technical

ONWORKS network,

Bulletin (LIT-1162150).
To connect the thermostat to the L

1. Connect the L
L

ONWORKS network terminal block on the

ONWORKS network wires to the

ONWORKS network:

thermostat (Figure 5 and Figure 6).
Note: There is no polarity when connecting the

L

ONWORKS network wires to the thermostat;

however, we recommend keeping the polarity
consistent throughout the network.

Setup and Adjustments

2. After the L

ONWORKS network wires are connected

to the first thermostat, continue in a daisy-chained
fashion to the next device.

Note: The L

ONWORKS network wiring must be

twisted-pair lines.

Do not run the L

ONWORKS network wiring in the same

conduit as line voltage wiring (higher than 30 VAC) or
other wiring that switches power to highly inductive
loads (such as contactors, coils, motors, or
generators).

The L

ONWORKS network requires proper termination

and biasing at the end of a segment (a segment is a
physically continuous length of wire). The thermostat is
not equipped with the ability to provide this termination;
therefore, it cannot be located at the physical end of a
L

ONWORKS network segment unless a terminator is

attached. Refer to L

ONWORKS Network Layout

Technical Bulletin (LIT-1162150) for end-of-line

solutions.

Thermostat User Interface Keys

The TEC22x6(H)-4 and TEC22x6H-4+PIR Series
Thermostat UI consists of five keys on the front cover
(Figure 11). The function of each key is as follows:

• MODE key toggles among the system modes
available, as defined by selecting the appr op ria te
operation sequence in the Installer Configuration
Menu (Off, Heat, Cool, Auto).

• FAN key toggles am on g th e fan mo de s available,
as defined by selecting the appropriate fan menu
options defined in the Installer Configuration Menu
(Low, Med, High, Auto).

Room Temp

frntvw

• OVERRIDE key (commercial models) overrides
the unoccupied mode to occupied at the local user
interface for the specified TOccT ime. (TOccTime is
defined by selecting the appropriate time period in
the Installation Configuration Menu.) If one of the
binary inputs is configured to operate as a remote
override contact, this OVERRIDE function is
disabled. The OVERRIDE key also allows access
to the Installer Configuration Menu. See the

Configuring the TEC22x6(H)-4 and
TEC22x6H-4+PIR Series Thermostat Controllers

section.

• °C/°F key (hospitality models) changes the
temperature scale to either Celsius or Fahrenheit
and allows access to the Installer Configuration
Menu. See the Configuring the TEC22x6(H)-4 and

TEC22x6H-4+PIR Series Thermostat Controllers

section.

• System Mode

• Occupancy Status
(Occupied/Unoccupied/Override)

• Applicable Alarms (The backlight lights up as an
alarm condition is displayed.)

Note: For hospitality models, binary inputs can
override the unoccupied mode to occupied mode.

• UP/DOWN arrow keys change the configuration
parameters and activate a setpoint adjustment.

Backlit Liquid Crystal Display (LCD)

The TEC22x6(H)-4 and TEC22x6H-4+PIR Series
Thermostats include 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 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 heat LED is on when heating is on.

• The cool LED is on when cooling is on.

Integrated PIR Sensor –
TEC22x6H-4+PIR Series Thermostat
Controllers

The integrated PIR sensor allows for automatic
switching between fully adjustable Occupied and
Stand-By temperature setpoints without user
interaction. This feature generates inc rem en tal energ y
savings during scheduled occupied period s while the
space is unoccupied.

Status Display Menu

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

• Room Temperature (All Models) and Humidity
(TEC2236-4, TEC2236H-4, TEC2236H-4+PIR,
TEC2256-4, TEC2256H-4, and TEC2256H-4+PIR
Models)

Note: For models with dehumidification capability,
the default setting is no humidity reading on the
display (%RH disp parameter is set to off.) The
%RH disp parameter must be set to on to display
the current humidity reading.

Note: An option is available within the Installer
Configuration Menu to lock out the scrolling display and
show only the Room Temperature parameter.

Status LED

The status LED shows the operational status of the
thermostat. The S tatus LED is a small green light un der
the thermostat cover (under the L

ONWORKS daughter

board on the left edge when facing the thermostat).

Dehumidification Operation – TEC2236(H)-4
and TEC2256(H)-4 Models Only)

Upon detection of space humidity above the adjust able
humidity setpoint as sensed by the internal humidity
sensor, dehumidification activates.

Note: Dehumidi fication operates only in Cooling
mode. Dehumidification does not operate in Off or
Heating system mode.

Note: A central network command can globally lock
out dehumidification to all thermostats.

If the room temperature resides in the deadband
between the Cooling and Heating Setpoint:

• the thermostat forces the fan to low speed

• the chilled water valve opens to the specified
maximum value set by CoolMax

• the thermostat stages heating to maintain space
temperature at the cooling setpoint as sensed by
the thermostat

If the room temperature falls below the curr en t he at ing
setpoint, the thermostat disables dehumidification.
