TEC3000 Series Networked and Wireless
Single- or Two-Stage Economizer Thermostat
Controllers Installation Guide
Applications
The TEC3000 Series Single- or Two-Stage Economizer
Thermostat Controllers are stand-alone and field-
selectable BACnet® MS/TP or N2 networked devices.
Wireless networked models of the TEC3000 Series
Thermostat Controller are also available. Series Single- or
Two-Stage Economizer Thermostat Controllers provide
control of the following:
• Unitary rooftop units (RTUs)
• Unitary RTUs with economizers
• Unitary heat pumps
• Unitary heat pumps with economizers
• Unitary RTUs with hot gas reheat
• Unitary RTUs with hot gas reheat and economizers
The networked models feature a field-selectable
Building Automation System (BAS) BACnet MS/TP or N2
communication capability that enables remote monitoring
and programming for efficient space temperature control.
The wireless models are compatible with the WNC1800/
ZFR182x Pro Series Wireless Field Bus System that enables
communication with a building automation system (BAS).
The wireless models (TEC30xx-xx-000) are compatible
only with the WNC1800/ZFR182x Pro Series Wireless Field
Bus System that enables communication with a building
automation system (BAS). The new wireless models
(TEC31xx-14-000) are compatible only with WRG1830/
ZFR183x Pro Series Wireless Field Bus System. All models
include a USB port configuration that reduces installation
time to allow simple backup and restore features from a
USB drive, which enables rapid cloning of configuration
between similar units.
Some models have occupancy sensing capability built into
the device. These thermostat controllers maximize up to
30% energy savings in high-energy usage commercial
buildings, such as schools and hotels, during occupied
times by using additional standby setpoints.
All models feature an intuitive onboard touchscreen
UI with backlit display that makes setup and operation
quick and easy. Only the single-speed fan configuration is
supported for fan coil equipment types.
All models contain a build-in humidity sensor to support
dehumidification on RTUs with hot gas reheat and RTUs
with auxiliary dehumidifier installed. When no heating
is required, the thermostat controller monitors the
space humidity and activates dehumidification control as
necessary. Heat, reheat or both are used as required to
prevent over-cooling while achieving humidity setpoint
and maintain the space temperature.
Important: The TEC3000 Series Thermostat
Controller is 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.
Important: Le TEC3000 Series Thermostat
Controller est destiné à transmettre des données
entrantes à un équipement dans des conditions
normales de fonctionnement. Lorsqu'une
défaillance ou un dysfonctionnement du
thermostat controller risque de provoquer des
blessures ou d'endommager l'équipement
contrôlé ou un autre équipement, la conception du
système de contrôle doit intégrer des dispositifs de
protection supplémentaires. Veiller dans ce cas à
intégrer de façon permanente d'autres dispositifs,
tels que des systèmes de supervision ou d'alarme,
ou des dispositifs de sécurité ou de limitation, ayant
une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du
thermostat controller.

Installation
Parts included
• One TEC3000 Series Thermostat Controller with integral
mounting base
• One installation instructions sheet
Location considerations
For networked models, locate the TEC3000 Series
Thermostat Controller:
• On a partitioning wall, approximately 5 ft (1.5 m) above
the floor in a location of average temperature, to allow
for vertical air circulation to the TEC
• Away from direct sunlight, radiant heat, outside walls,
outside doors, air discharge grills, stairwells, and from
behind doors
• Away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or sources
of electrical interference
• In a clear path between the integrated passive infrared
(PIR) occupancy sensor, if equipped, and the space it
monitors
For wireless models, also locate the thermostat controller:
• Outside of a recessed area, metal enclosure, or shelving
unit
• On the same building level as the other wireless devices
on the same personal area network (PAN)
• At least 2 in. (51 mm) away from any metal obstruction
• In the direct line of sight to other wireless devices on
the same PAN. Signal transmission is best if the path
between the TEC3000 and other wireless devices is
direct as possible. Line of sight is desirable but not
required. See Table 1 and Table 2 for the recommended
and maximum distances.
• Away from metal and large solid obstructions, that
includes equipment rooms and elevator shafts and
concrete or brick walls, between the TEC3000 and
the ZFR182x or ZFR183x Router/Repeater or ZFR Pro
Coordinator Radio
• Within range of two or more wireless devices on the
same PAN. Redundancy in the layout provides the best
reliability in wireless installations
• At least 20 ft (6 m) from a microwave oven
For integrated PIR models, make sure that the thermostat
controller is located centrally, where occupant movement
is frequent. Ensure that the unit is not blocked by a plastic
tamper resistant enclosure (such as the GRD10A-608). The
plastic enclosure blocks the occupancy sensing capability.
The use of insulating foam pads is necessary for
installations where wiring passes through the wall to the
thermostat.
For wireless models, the effective transmission range and
distance for indoor applications vary because of wireless
signal absorption and reflection due to metal obstructions,
walls or floors, and furniture that is found in building
interiors.

3. Align the thermostat controller mounting base on
the wall with the security screw on the top and use
the base as a template to mark the two mounting
hole locations. See Figure 3.
- If you need to install the thermostat controller
on an electrical junction box, use 2-1/2 in. x
4 in. (63 mm x 101 mm) square boxes with
mud ring covers and avoid smaller 1-1/2 in.
x 4 in. (38 mm x 101 mm) square or 3 in. x 2
in. (76 mm x 51 mm) boxes. This procedure
ensures that you have enough space for
cabling, if needed.
- For surface-mounted applications, use durable
mounting hardware, such as wall anchors, that
cannot be easily pulled out of the mounting
surface.
4. Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the center hole
in the thermostat controller mounting base. See
Figure 3.
5. Secure the mounting base to the wall surface using
two mounting screws (user supplied) as illustrated
in Figure 3.

terminals, make sure to twist the wires together
before you insert them into the terminal
connectors.
3. 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.
4. For networked models, set the bus end-of-line (EOL)
termination switch to the desired location.
You can designate the thermostat controller as
the end of the Field Controller (FC) Bus and N2
Bus through the bus EOL termination switch.
The default position is OFF. If the thermostat
controller is at the end of a daisy chain of
TEC3000 Series Networked and Wireless Single- or Two-Stage Economizer Thermostat Controllers Installation Guide4

devices on the FC Bus and N2 Bus, set the EOL
switch to the ON position. See Figure 5.
