Part No. 24-9890-1168, Rev. B

Issued July 13, 2010

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. TEC200x-4 Series Wireless Thermostat
Controllers provide networked control of a variety of
staged equipment. TEC2004-4 and TEC2004-4+PIR
Multi-Stage Economizer Wireless Thermostat
Controllers control economizer operation for single­and multi-stage unitary rooftop equipment.

The TEC2004-4+PIR Thermostat Controller provides
advanced active occupancy logic that automatically
switches occupancy from Occupied to Unoccupied as
required by the presence of local activity. See the

Occupancy Sensor Operation – TEC2004-4+PIR
Thermostat Controller 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 TEC2004-4 and
TEC2004-4+PIR 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.

technical specifications were met.

Le terme « IC » précédant le numéro d'accré ditation /
inscription signifie simplement que le produit est
conforme aux spécifications techniques d'Industrie
Canada.

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 cover and open the
thermostat controller 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, outside doors, air discharge grills, or
stairwells, or from behind 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.

Note: Allow for vertical air circulation to the thermostat
controller.

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.

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

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.

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

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 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.

CAUTION: Risk of Electric Shock.

Disconnect 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.
