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 Controller:

• 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

For integrated Passive Infrared (PIR) models, make
sure the thermostat controller is located centrally,
where occupant movement is frequent.

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.

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).

• 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

• 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.

temperature rises 2°F above the cooling setpoint, the
thermostat automatically disables dehumidification. If
the thermostat is in cooling demand and the room
temperature falls below the current heating setpoint,
the thermostat disables dehumidification.

Occupancy Sensor Operation –
TEC22x6H-4+PIR Series Thermostat
Controllers

A TEC22x6H-4+PIR Series Thermostat Controller (or a
TEC22x6(H)-4 Series Thermostat Controller equipped
with a PIR accessory cover) provides advanced
occupancy logic.

Note: The PIR strategy is an occupied strategy. If the
thermostat controller is programmed to be Unoccupied,
the PIR function does not have an effect on the
occupancy strategy.

The thermostat controller automatically switches
occupancy levels from Occupied to Stand-By and
Unoccupied as required, when local movement is
sensed.

Occupancy sensing is enabled only if a PIR cover is
installed on the thermostat controller (PIR models) or if
a remote input is configured as a remote PIR sensor
(MotionNO or MotionNC).

PIR Warm-Up Period

When a PIR cover is used and a thermostat controller
is powered up, there is a 1-minute warm-up period
before any local movement can be detected and
acknowledged by the PIR sensing device. The local
status LEDs for the PIR function are not active, and the
sensor is in Stand-By mode for the 1-minute period.
The PIR functionality and local movement status LEDs
are activated after the 1-minute warm-up period has
elapsed after the initial powering of the thermostat
controller. If movement is present, the mode changes
to Occupied.

PIR Diagnostic LEDs

The diagnostic LEDs inside the PIR lens brighten when
movement is detected within the first 30 minutes after
powerup. The LEDs do not light up or brighten after the
initial 30-minute period.

Setpoints

The Stand-By setpoints are under the same limitations
and restrictions as the Occupied and Unoccupied
setpoints. Stand-By setpoints reside between the
corresponding Occupied and Unoccupie d se tp oint
values.

The installer must be certain that the difference
between the Stand-By and Occupied values can be
recovered within a timely fashion to ensure occupancy
comfort. In addition, the difference between the two
values must be large enough to warrant maximum
energy savings.

Hotel and lodging applications can benefit from the
addition of an entry door switch wired to one of the
binary inputs of the thermostat controller. When a door
contact is used and configured, the S ta nd-By timer and
its configuration are no longer active or used. The
occupancy toggle between Occupied and Stand-By is
then dictated by both the door contact an d the
PIR sensing device used. If movements are detected
by the PIR sensor and the door is closed, the room is
considered occupied. The thermostat controller
switches back to St and-By mode only if the door switch
toggles open/closed. Motion is ignored when the door
switch indicates an open door.

PIR occupancy functionality is dictated by both the
Stand-By timer and Unoccupied timer configuration
value and movements present in the area.

It might be preferable for the local area to stay out of
Unoccupied mode and always stay at the Stand-By
occupancy level when no activity is present. In
instances when areas always need to be in Stand-By
mode, ready to respond to demand at any given point
in time, we recommend disabling the Unoccupied timer .
When the local PIR occupancy routine is running at the
thermostat controller, the zone drifts into Unoccupied
mode when the Unoccupied timer is set above its
factory default value of 0.0 hours.

Configuring the Thermostat Controller’s
Neuron® Identification

Press and hold the UP/DOWN arrow keys
simultaneously for 5 seconds to broadcast the
thermostat controller’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 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.

Each input can be configured to the Selection Options
included in Table 5.

Configuring the Sequence of Operation
(SeqOpera)

Choose the appropriate sequence of operation. The
modes presented are user-dependent on the sequen ce
of operation selected. For 2-pipe applications using a
COS, choose 0 = Cooling only. Changeover occurs
between Cooling on ly and Heat ing only. For example
sequences of operation, see Figure 15 through
Figure 20.

Default: None

(Rem NSB): Remote Night Setback (NSB) via a time clock input, an

occupancy sensor, or from a voltage-free contact.

Contact open = Occupied; contact closed = Unoccupied.

(MotionNO*): Temporary occupancy request via a motion detector

input. Contact open = Unoccupied. When th e contact closes, the

thermostat goes into the occupied mode for a specified TOccTime.

Once the TOccTime begins, the thermostat remains in the occupied

mode if the contact is open, until the TOccTime expires.

(MotionNC*): Temporary occupancy request via a motion detector

input. Contact closed = Unoccupied. When the contact opens, the

thermostat goes into the occupied mode for a specified TOccTime.

Once the TOccTime begins, the thermostat remains in the occupied

mode if the contact is closed, until the TOccTime expires.

(Window): Cancels the thermostat heating or cooling action when a

window is open. The fan operation is only affected if the Fan Menu

parameter is set to (4): On-Auto and Auto is the selected fan mode.

A Window alarm appears, indicating that the window needs to be

closed to resume heating or cooling.

*These settings disable any local override function.

(None): No function is associated with an input.

(Door Dry): Door contact only has an effect if BI1 is set to MotionNO

or MotionNC. (See the BI1 parameter in this table.) The occupancy

is now dictated via BI1 and BI2. Any motion detected sets the zone

to Occupied status. The zone remains permanently in occupied

mode until the door contact switch opens momentarily. The

thermostat then enters stand-by mode. If more movements are

detected, the occupied mode resumes. While the door is opened,

any movements detected by the remote PIR sensor or the PIR

accessory cover are ignored. Use a Normally Closed contact

switching device. Contact opened = Door opened,

Contact closed = Door closed.

(RemOVR): Temporary occupancy request via a remote input. This

override function is controlled by a manual remote occupancy

override. When enabled, this condition disables the override

capability of the thermostat.

(Filter): A Filter alarm is displayed. This alarm can be connected to

a differential pressure switch that monitors a filter.

(Service): A Service alarm is displayed on the thermostat when the

input is energized. This input can be tied into the air conditioning unit

control card, which provides an alarm should there be a malfunction.
