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

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.

Installer configuration menu
The thermostat controller comes from the factory with
default settings for all configuration parameters. The
UI menu navigation and default settings are shown in
Table 14. Before any outputs turn on, the controller must
be configured for the equipment connected. You need
to start from the home screen to perform any of the
following tasks.
Screen reset
The current screen returns to the home screen and turns
off if the current screen is not touched for 3 minutes.
Touch the screen to turn it on again. To disable the
screensaving option, press Display Settings and set

Selecting Rooftop or Heat Pump mode
About this task:
By default, the thermostat controller is configured for
Rooftop mode. This mode is used for up to two discrete
stages of heating (W1, W2) and up to two discrete stages
of cooling (Y1, Y2). Certain heat pumps do not require an
O/B input and instead take standard W and Y commands
as heat or cool commands, internally sequencing the
equipment. For these type of heat pump units, leave the
controller in Rooftop mode.
When in heat pump mode, the TEC controls up to two
stages of compressors (Y1, Y2) for both heating and
cooling. O/B is controlled through the W1/OB output and
one stage of supplemental heat is controlled through the
W2/SUP output. To configure heat pump mode, complete
the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press Heat Pump.
5. Press Heat Pump Supported and select Yes.
6. If supplemental heating is installed, press Supp
Heating Installed and select Yes.
7. Press Reversing Valve Polarity and set
appropriately for the O/B input on the equipment
based on if the equipment is normally cooling until
the thermostat output is activated or normally
heating (typically, Normally Heat for O and
Normally Cool for B).
8. Press Save and the back arrow to return to the
previous screen.

Configuring economizer
About this task:
If the equipment has an analog (between 0 VDC to
10 VDC) input for an economizer damper command,
configure the economizer as follows:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press Economizer.
5. Press Economizer Installed and select Yes.
6. Press Min Position and set to the percentage that
the damper must be kept open to ensure fresh air
flow in the zone.
7. Press Closed Voltage and set to the voltage output
at which the damper is fully closed.
8. Press Opened Voltage and set to the voltage output
at which the damper is fully opened.
9. Press Save and the back arrow to return to the
previous screen.
The TEC supports three methods of determining
economizer availability. These are Dry Bulb, Single
Enthalpy, and Dual Enthalpy, in increasing order of
accuracy. To run an economizer, outdoor air temperature
(OAT) is required to run in Dry Bulb mode. This can be
provided by connecting a sensor to the OAT input on the
TEC. It also can be provided by writing to NET-OAT from
a Building Automation System (BAS), which overrides
the internal sensor. If Outdoor Air Humidity (OAH) is
also provided by writing to NET-OAH, the dual enthalpy
method is used to determine if economizer cooling should
be used.
All network overrides to the TEC work on a timeout basis.
If the value is written to, it remains active as long as the
BAS writes a new value within 15 minutes of the first one.
If the 15-minute timeout occurs without getting any data
written, the TEC stops using the network data.
When operating in Dry Bulb or Single Enthalpy mode,
it is necessary to provide a Dry Bulb Setpoint or an OA
Enthalpy Setpoint, respectively. The TEC ships with default
values set, but depending on climate it may be necessary
to change these. To access these values, complete the
following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press Economizer.
5. Press Dry Bulb Setpoint or Outdoor Enthalpy
Setpoint and adjust according.
6. Press Save and the back arrow to return to the
previous screen.

Setting the Control mode
About this task:
The Control Mode informs the controller to run in Cooling
only, Heating only, or Automatic mode, based on the
temperature in the zone relative to the heating and
cooling setpoints. Control Mode does not override
equipment lockouts or changeover. To set the Control
Mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Control Mode and select Cooling, Heating,
or Auto as preferred.
5. Press Save and the back arrow to return to the
previous screen.
Setting the Fan mode
About this task:
The Fan Mode informs the controller how to handle
the fan. There are two options for fan configuration: a
Fan Mode available to the installer through the menu
system, and a fan override available as an option to the
end user from the Fan icon on the home screen. See
Customizing the home screen for information on enabling
and disabling end-user controls. The Fan Mode available
to the installer depends on the fan type. The following
options are provided for single-speed fans:
• On—Fan is continuously on
• Auto—Fan cycles on demand with the controller
entering cooling, heating, or dehumidification modes
• Smart—Fan cycles on demand with the controller
entering cooling or heating modes during unoccupied
periods but is continuously running during occupied
and standby periods
The Fan Override icon on the home screen depends
on the fan type. The following options are provided for
single-speed fans:
• On—Overrides the fan to be continuously on
• Auto—Follows the behavior set as Fan Mode
• Quiet—Follows the behavior set as Fan Mode, but
prevents the fan from ever going above minimum
speed. The Quiet option has no effect on equipment
with single-speed fans.
To set the Fan Mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Fan Mode and select On, Auto, or Smart.
5. Press Save and the back arrow to return to the
previous screen.
Configuring the zone space or
equipment size
About this task:
With non-binary outputs, the TEC3000 default
configuration is to have a slower temperature response
for larger zones with normal-sized equipment. In
installations with small zones and oversized equipment,
set the Equipment Size parameter to Oversized.
To set the Equipment Size parameter, complete the
following steps:
1. Press the Menu icon.
2. Press Control Setup.
3. Press Tuning.
4. Use the up and down arrows to navigate to
Equipment Size.
5. Press Equipment Setup and select Oversized.
6. Press Save and the back arrow to return to the
previous screen.
Temperature setpoints
About this task:
The thermostat controller provides a flexible setpoint
configuration to give power to the building owner while
being easy to use by the occupant. In addition to a simple
up/down offset adjustment on the home screen for the
occupant, there are six temperature setpoints on the TEC.
The six temperature setpoints are Cooling and Heating
setpoints for Occupied, Unoccupied, and Standby modes.
To set these setpoints, complete the following steps:
1. Press the Menu icon.
2. Press Setpoints and then Temperature.
3. Select the setpoint to adjust and change as
preferred.
4. Press Save and the back arrow to return to the
previous screen.
Note: The TEC enforces a 2-degree deadband
between heating and cooling setpoints. If a
setpoint violates this standard (for example,
cooling setpoint is set to 70 with a heating
setpoint already set to 70), the opposing
setpoint is modified to comply with this
deadband (in the previous example, the
heating setpoint would automatically change to
68).
Result
The occupant has access to an up/down adjustment from
the home screen. This adjustment applies a fixed offset
(+/-) to the currently active setpoint, and this offset holds
until the occupancy state of the controller changes. If
the user taps the setpoint on the home screen, the icon
inverts and displays white text on a black icon. The offset
is held throughout all occupancy periods. For example,
if the TEC is cooling in Occupied mode to an occupied
cooling setpoint of 72 and you raise the setpoint 2
degrees to 74 from the home screen and then select hold,
then the +2 degree offset persists through an occupancy
change. If the occupancy then changes to unoccupied,
TEC3000 Series Networked and Wireless Single- or Two-Stage Economizer Thermostat Controllers Installation Guide18

with a setpoint of 80 degrees, the effective setpoint is 82
degrees. This allows the occupant to have a small amount
of control over raising or lowering the temperature, but
the building owner can still set back setpoints during
standby and unoccupied periods. When the setpoint is in
Hold mode, pressing the icon again releases the hold and
immediately sets the setpoint offset back to 0.
When the TEC is in Min/Max mode (Setpoints/Occ
Setpoint Select are equal to Min and Max Setpoint), the
TEC rejects any attempts to change the present value
outside of the valid range. If the present value is outside
of the valid range (for example, if the Occ Setpoint Select
is switched from Setpoint Offset to Min and Max Setpoint),
the present value is reset to be in the center of the valid
range.
The four modes of setpoint operation are described in
Table 8.

This is the default mode and the original
mode of operation that the TEC was
released with (the next three modes are
new). In this mode, the TEC has a heating
setpoint and a cooling setpoint. There is a
common Setpoint Offset (warmer/cooler
adjust) that applies to each setpoint
simultaneously. The range of setpoint
adjustment is two-fold:
• There are large constant ranges
bounding the individual heating and
cooling setpoints.
• There is also a smaller configurable
range limit set to the Setpoint Offset
point (Control Setup > General > Max
Setpoint Offset).

In this mode, the TEC has a heating
setpoint and a cooling setpoint. Each
setpoint has a configurable range
(Setpoints > Temperature > Min Cooling
Setpoint, Max Cooling Setpoint, Min
Heating Setpoint, and Max Heating
Setpoint). The configurable range values
are bounded by the larger constant
bounds used in Setpoint Offset mode and
are constrained in the following manner:
Min must be below Max and Heating
must be below Cooling, so in order from
least to greatest, the values are: Min
Heating Setpoint, Max Heating Setpoint,
Min Cooling Setpoint, and Max Cooling
Setpoint.
Occ Setpoint

Offset (warmer/cooler adjust) that only
applies to Common Setpoint. Otherwise,
this setting works the same as when Occ
Setpoint Select = Setpoint Offset and Heat
Cool Setpoint Mode = Individual Setpoints.
Occ Setpoint

Configuring occupancy
To adapt to nearly any application, the TEC3000 controller
supports a wide variety of occupancy sources, such as:
• Local stand-alone weekly scheduler
• Remote schedule from BAS
• Occupancy sensor (internal or remote)
• Occupancy binary input (configurable)
• Manual occupancy override
• Temporary occupancy (by interacting with the screen
while in unoccupied mode)
• Temporary occupancy binary input
Occupancy is determined using a top-down decision
matrix as shown in Table 9.
Enumerations may not match the TEC3000 Series

the BI when configured as Occupancy.
2 True is triggered by interacting with the screen during a scheduled unoccupied period. A value of True can only occur when the
schedule is not Occupied.
3 When triggered by a BI configured for Temp Occ, the input is ignored when the schedule is Occupied, the Manual Occupancy Mode
is not No Override, or an Occupancy BI is configured.
4 Built-in occupancy sensing (PIR) or BI configured for Motion NO or Motion NC.
5 Not Set occurs when no events are scheduled through the local scheduler, or the schedule source is set to Schedule and the
Schedule is writing Not Set as the schedule.
