Applications

The TEC Series Wireless Thermostat Controller
System provides wireless networked control of
Heating, Ventilating, and Air Conditioning (HVAC)
equipment on a Building Automation System (BAS)
that enables remote monitoring and programming. This
TEC Series System integrates into a supervisory
controller that uses BACnet® Internet Protocol (IP) or
BACnet Master-Slave/Token-Passing (MS/TP)
communications.

TEC20 Coordinators allow the supervisory controlle r to
communicate with multiple TEC Wireless Thermostat
Controllers. TEC20x6(H)-4 and TEC20x6H-4+PIR
Series Wireless Thermostat Controllers control two- or
four-pipe fan coils, cabinet unit heaters, or other
equipment using on/off, floating, or proportional
0 to 10 VDC control input, three speeds of fan control,
and dehumidification capability.

The TEC20x6H-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 – TEC20x6H-4+PIR Series
Thermostat Controllers section for more information.

The wireless mesh network uses ZigBee™ technology
to enable remote monitoring and programming and to
enhance reliability by providing redundant transmission
paths through other TEC Wireless Thermostat
Controllers, creating a resilient, self-healing mesh
network.

IMPORTANT: The TEC20x6(H)-4 and
TEC20x6H-4+PIR Series Wireless 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 controller.

Installation

Location Considerations

Locate a thermostat controller:

• on a partitioning wall, approximately 1.5 m (5 ft)
above the floor in a location of average
temperature

For detailed information on locating devices for
optimum signal strength, refer to the Wireless Metasys
System Location Guide (LIT-12011294).

Installing the Thermostat Controller

Follow these steps to install the thermostat controller:

1. Use a Phillips-head screwdriver to remove the
security screw if it is installed on the bottom of the
thermostat controller 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 . Car efully 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.

• 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
TEC20x6(H)-4 and TEC20x6H-4+PIR Series
Thermostat Controllers.

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

Wireless Signal Transmission Range

Line-of-sight transmission ranges between a
TEC20 Coordinator and a TEC Wireless Thermostat
Controller (or between TEC Wireless Thermostat
Controllers) can be less than the recommended
distances shown in Table 1. The effective transmission
range for indoor applications varies because of Radio
Frequency (RF) signal absorption and re flectio n due to
metal obstructions, walls (or floors), and furniture found

in typical building interiors.

4. Pull approximately 152 mm (6 in.) of wire from the
wall and insert the wire through the hole in the
mounting base.

5. Align the mounting base on the wall, and use the
base as a template to mark the two mounting hole
locations.

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)
square or 3 x 2 in. (76 x 51 mm) boxes. This
procedure ensures you have enough space for
cabling and end-of-line devices, if needed.

snap it into the locking tabs on the mounting base.

9. Remove the screw terminal blocks that are
attached to a disposable adhesive. Figure 4
illustrates the locations of the screw terminal
blocks on the thermostat controller.

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

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

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.

CAUTION: Risk of Electric Shock.

Disconnect the power supply before
making electrical connections to avoid
electric shock.

CAUTION: Risk of Property Damage.

Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.

To wire the thermostat controller:

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

Note: If multiple wires are inserted into the screw
terminals, be sure to properly twist the wires
together prior to inserting them into the screw
terminals.

2. Carefully push any excess wire back into the wall.
Note: Seal the hole in the wall with fireproof

material to prevent drafts from affecting the
ambient temperature readings.

IMPORTANT: Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the thermostat controller.

When replacing an existing thermostat controller,
remove and label the wires to identify the terminal
functions. When replacing a thermostat controller of the
same model, simply remove the old screw terminal
blocks and reinsert them onto the PCB of the
replacement thermostat controller.

3. Reinsert the screw terminal blocks onto the PCB.
Note: If multiple wires are inserted into the

terminals, be sure to properly twist the wires
together prior to inserting them into the terminal
connectors.

4. Reattach the cover to the mounting base (top side
first).

5. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the cover.

Integrated PIR Sensor –
TEC20x6H-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 incremental energy
savings during scheduled occupied periods while the
space is unoccupied.

Backlit Liquid Crystal Display (LCD)

The thermostat controller includes a 2-line, 8-ch aracter
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.

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.

• System Mode

• Occupancy Status (Occupied/Unoccupied/
Override)

• Applicable Alarms – The backlight lights up as an

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

Dehumidification Operation –
TEC2036(H)-4 and TEC2056(H)-4 Thermostat
Models

Upon detection of room humidity above the adjustable
humidity setpoint as sensed by the integral humidity
sensor, dehumidification activates.

Note: Dehumidification operation functions only in the
Cooling mode; dehumidification operation does not
function in either the Off or the Heating mode.

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

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

• the thermostat forces the fan to low speed

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

TEC20x6(H)-4 and TEC20x6H-4+PIR Series Wireless Thermostat Controllers with Dehumidification

• the thermostat stages Heating to maint ain the room
temperature at the Cooling setpoint, as sensed by
the thermostat

If the room temperature falls below the current Heating
setpoint, the thermostat disables dehum idification
operation.

9

Capability, Fan Control, and Occupancy Sensing Capability

If the thermostat is in Cooling demand:

• the chilled water valve opens to 100%

• the thermostat stages Heating to maint ain the room
temperature at the Cooling setpoint, as sensed by
the thermostat

If the thermostat is in Cooling demand and the room
temperature rises 2F°/1C° above the Cooling setpoint,
the thermostat automatically disables dehumidification
operation. Likewise, if the thermostat is in Cooling
demand and the room temperature falls below the
current Heating setpoint, the thermostat disables
dehumidification operation.

Occupancy Sensor Operation –
TEC20x6H-4+PIR Series Thermostat
Controllers

A TEC20x6H-4+PIR Series Thermostat Controller–or a
TEC20x6(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 t and-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 and 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 S tand-By m ode 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.

Unoccupied Timer Disable

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 on Stand-By
status, 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.

For more information on occupancy sensor operation,
refer to the TEC2x45-4, TEC2xx6(H)-4,

TEC2xx6H-4+PIR, and TEC2xx7-4 Series Thermostat
Controllers Application Note (LIT-12011594).

Configuring the Wireless Mesh Network
Settings

Use the following process to configure the wireless
mesh network.

1. Select a PAN ID and Channel. Use these same
values for every TEC Wireless Thermostat
Controller (and the associated TEC20 Coordinator)
on the same wireless mesh network. See Table 6.

2. Select a Com Address for each TEC Wireless
Thermostat Controller (1 to 254). This address
must be unique to each TEC Wireless Thermostat
Controller on the same wireless network (that is,
unique to the PAN ID/Channel combination). See
Table 6.

After configuring the wireless mesh network settings,
refer to the TEC20xx-4 and TEC20xx-4+PIR Series

Wireless Thermostat Controller System Technical
Bulletin (LIT-12011596) for directions on integrating the

TEC Wireless Thermostat Controllers and TEC20
Coordinator with a supervisory controlle r.

Dehumidification (TEC2036[H]-4, TEC2036H-4+PIR,
TEC2056[H]-4, and TEC2056H-4+PIR Models Only)

Upon detection of room humidity above the adjustable
humidity setpoint as sensed by the integral humidity
sensor, dehumidifica tion activates.

Note: Dehumidification operation functions only in the
Cooling mode; dehumidification operation does not
function in either the Off or the Heating mode.

Note: A central network command can globally
lock out dehumidification operation to all thermostat
controllers.

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

• the thermostat controller forces the fan to low
speed

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

• the thermostat controller stages Heating to
maintain the room temperature at the Cooling
setpoint, as sensed by the thermostat controller

If the room temperature falls below the current Heating
setpoint, the thermostat controller disables
dehumidification operation.

If the thermostat controller is in Cooling demand:

• the chilled water valve opens to 100%

• the thermostat controller stages Heating to
maintain the room temperature at the Cooling
setpoint, as sensed by the thermostat controller

If the thermostat controller is in Cooling demand and
the room temperature rises 2F°/1C° above the Cooling
setpoint, the thermostat controller automatically
disables dehumidification operation. Likewise, if the
thermostat controller is in Cooling demand and the
room temperature falls below the current Heating
setpoint, the thermostat controller disables
dehumidification operation.

(None): No function is associated with an input.
(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 the contact closes, the
thermostat controller goes into the occupied mode for a specified
TOccTime. Once the TOccTime begins, the thermostat controller
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 controller goes into the occupied mode for a specified
TOccTime. Once the TOccTime begins, the thermostat controller
remains in the occupied mode if the contact is closed, until the
TOccTime expires.

(Window): Cancels the 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 earlier 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 controller.

(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 controller
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.
