TEC3000 Series On/Off or Floating Fan

Coil Thermostats Installation Guide

Applications

The networked TEC3000 Series 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. On/Off or Floating Fan Coil and Individual Zone
Thermostat Controllers provide control of the following:

• Local hydronic reheat valves

• Pressure-dependent variable air volume (VAV) equipment with or without local reheat

• Two- or four-pipe fan coils

• Cabinet unit heaters

• Other individual zone equipment using an on/off or floating control input

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). All models include a USB port configuration that reduces installation time by allowing
simple backup and restore features from a USB drive, which enables rapid cloning of configuration
between like units.

Some models feature built-in occupancy sensing capability. 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. Multiple fan configurations are supported for fan coil equipment types,
as follows:

• Single-speed

• Multi-speed (two or three discrete speeds)

• Variable-speed/EC motors (0 to 10 VDC control)

Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan
coil units with or without reheat. When no heating is required, the thermostat controller monitors
space humidity and activates dehumidification control as necessary. Heat and/or reheat is used as
required to maintain the space temperature. For optimal dehumidification performance, use a fan
coil unit that has a multi-speed or variable-speed fan (VSF).

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.

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide2

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, allowing 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 being monitored

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 for recommended and maximum distances.

• Away from metal and large solid obstructions (including equipment rooms and elevator shafts
and concrete or brick walls) between the TEC3000 and the ZFR Pro 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, be 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 required 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 found in typical building interiors.

Selecting the unit type

About this task:

The following three unit types are available:

• Four-pipe—This unit type has both heating and cooling coils plus a supply fan. This configuration
can also be used on configurations that are heating or cooling only.

• Two-pipe—This unit type has a single set of pipes that can serve hot or chilled water plus a
supply fan. The Supply Temp Type allows for the connection of an analog sensor or an aquastat
to a binary input. Based on the water temperature or aquastat state, the unit controls heating or
cooling.

• VAV—This unit type is designed for a pressure-dependent zone damper and the supply fan
outputs are disabled. The TEC senses the supply air temperature coming from the unit.
The Supply Temp Type setting allows for the connection of an analog sensor or binary duct
thermostat. Based on the air temperature or duct thermostat state, the zone damper controls for
heating or cooling. The TEC does not control the unit delivering the air. The logic needs to be part
of another controller.

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide28

For VSF control, the output is configurable for any range between 0 V and 10 V. The parameters are
Start Voltage, Full Speed Voltage, and Minimum Command. Start Voltage is the voltage output at
which the fan begins running, and Full Speed Voltage is the voltage output at which the fan reaches
full speed. Minimum Command is the percentage of the range between the Start Voltage and the
Full Speed Voltage. The fan does not go below the minimum command when the fan is turned on.
By default, the Start Voltage is 2 V, the Full Speed Voltage is 10 V, and the Minimum Command is
20%.
When the variable speed fan is off, the FAN L binary output is off and the voltage at the VSF out­put is 0 V. When the fan turns on, the FAN L binary output turns on and the voltage at the VSF out­put begins controlling the fan. When the VSF is configured for reverse acting mode, when the Start
Voltage is above Full Speed Voltage, the VSF output is set to 10 V or the Start Voltage minus 1 V,
whichever value is the lesser, when the fan is turned off.

6. Press Save and the back arrow to return to the previous screen.

Changeover

About this task:

Pressure-Dependent VAV systems and two-pipe fan coils require changeover detection in order to
switch seasonal operation between heating and cooling modes. The TEC supports the following
methods for changeover: automatic changeover using an analog sensor (thermistor), automatic
changeover using a binary switch, or remote changeover from a BAS and manual changeover.
For automatic changeover, a supply temperature sensor or switch must be connected to the
Changeover Sensor (COS) input of the TEC. Changeover Mode must be set to Auto, and Supply
Temp Type must be set for Analog Sensor, Cooling N.C. (cooling when switch is closed), or Heat­ing N.C. (heating when switch is closed). When an analog sensor is used, the changeover setpoint
can be adjusted. The changeover logic applies a 10-degree Fahrenheit differential to the setpoint.
The system switches to cooling mode when the temperature drops below the changeover set­point and remains in cooling mode until the measured temperature has risen 10 degrees above the
changeover setpoint.
To configure automatic changeover:

1. Press the Menu icon.

2. Press Setup.

3. Press Equipment Setup.

4. Press Changeover.

5. Press Changeover Mode and select Auto.

6. Press Supply Temp Type and select Analog Sensor, Cooling N.C., or Heating N.C.

7. If using an Analog Supply Temp Sensor, press Supply Temp Type and adjust accordingly.

8. Press Save and the back arrow to return to the previous screen.

Additionally, the thermostat controller supports manual changeover. To configure manual
changeover:

1. Press the Menu icon.

2. Press Setup.

3. Press Equipment Setup.

4. Press Changeover.

5. Press Changeover Mode and select Heating or Cooling.

6. Press Save and the back arrow to return to the previous screen.

You need to ensure that the Supply Temp type is set to Analog Sensor. The Changeover Mode is
also exposed to the BAS through the CGOVR-MODE and can be commanded from the BAS.

On two-pipe or VAV systems without an automatic changeover, or on four-pipe systems, you can
use RSEN or COS as a monitor-only point for reading an analog sensor. By setting the controller
in four-pipe mode, or selecting Heating or Cooling for Changeover Mode, the controller defaults
to monitor-only mode for RSEN or COS and exposes the value to the network as the supply
temperature.

Dehumidification control - fan coil only

About this task:

The TEC3000 controller support dehumidification control on fan coil devices under three configura­tions:

• Four-pipe fan coil

• Four-pipe fan coil with reheat

• Two-pipe fan coil (with changeover in cooling mode) with reheat

For optimal dehumidification performance, a 4-pipe unit with floating/incremental or 0 to 10 V con­trol and a multi-speed or variable-speed fan is recommended.
Dehumidification operates when the zone humidity increases above the zone humidity setpoint and
the controller is in the Idle or Cooling state. Dehumidification does not operate during heating and
stops if the zone temperature drops below the heating setpoint. When dehumidification is active,
the cooling device controls to the humidity setpoint, and the heating device reheats the zone in
order to keep the temperature at the cooling setpoint. While in the dehumidification mode, a multi­speed or variable-speed fan runs at the lowest possible speed to maximize condensation and mois­ture removal across the cooling coil.
To enable dehumidification control:

1. Press the Menu icon.

2. Press Setup.

3. Press General Control Setup.

4. Press Dehum Enable and select Yes.

5. Press Save and the back arrow to return to the previous screen.

This point is also exposed to the BAS through the point DEHUM-EN.
To adjust the dehumidification setpoint:

1. Press the Menu icon.

2. Press Setpoints.

3. Press Dehumidification and adjust accordingly.

4. Press Save and the back arrow to return to the previous screen.

This point is also exposed to the BAS through the point DEHUM-SP.

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, the TEC features six temperature setpoints. 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.

3. Select the setpoint to adjust and change as desired.

4. Press Save and the back arrow to return to the previous screen.

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide32

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).

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, 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 following table describes the four modes of setpoint operation.

Table 7: Setpoint operation

Mode of setpoint
operation

Occ Setpoint Select =
Setpoint Offset and
Heat Cool Setpoint
Mode = Individual
Setpoints

Details

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 is applied to each setpoint
simultaneously. The range of setpoint adjustment is two-fold:

Occ Setpoint Select =
Min and Max Setpoints
and Heat Cool Setpoint
Mode = Individual
Setpoints

Occ Setpoint Select =
Setpoint Offset and
Heat Cool Setpoint
Mode = Common
Setpoint

• 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 > 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.

In this mode, the TEC has one setpoint, Common Setpoint, for heating
and cooling. There is also a common Setpoint Offset (warmer/cooler
adjust) that is only applied to Common Setpoint. Otherwise, this setting
works the same as when Occ Setpoint Select = Setpoint Offset and Heat
Cool Setpoint Mode = Individual Setpoints.

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 8.

Enumerations may not match TEC3000 Series Networked and Wireless On/Off or Floating Fan Coil

Scheduling (for networked models)

About this task:

The TEC3000 Thermostat Controller can operate as a stand-alone unit with an internal schedule or
scheduled with an external schedule. The OCC-CONFIG object sets the method used for scheduling.
If the OCC-CONFIG is set to External, the NET-OCC object is used to control the unit externally.
If the OCC-CONFIG is set to Schedule, the internal schedule commands the LOCAL-OCC object,
which sets the Occupancy Schedule command.

Note: If you do not have a schedule in the Schedule object and you have the OCC-CONFIG set
to Schedule, you can control the unit with the LOCAL-OCC object externally; however, we do
not recommend this method. See Table 9 for scheduling information.

Once the Occupancy Schedule command is set, the effective occupancy is determined by
settings shown in the Occupancy Determination table. See Table 8.

Scheduling (for all models)

The occupancy schedule comes from either the weekly scheduler built into the TEC or as an
input from the BAS. The Schedule Source must be selected to tell the controller where to read
the occupancy source from. To select the schedule source:

1. Press the Menu icon.

2. Press Scheduling.

3. Press Schedule Options.

4. Press Schedule Source and select Schedule (Local) or External (BAS).

5. Press Save and the back arrow to return to the previous screen.

This option is also exposed to the BAS through the point OCC-CONFIG. If BAS is configured as
the occupancy source, map the point NET-OCC in and write to that point to control the schedule
remotely. If the supervisor goes offline (as identified by the network icon going away on the home
screen of the TEC), the control logic automatically falls back to the local schedule as the occupancy
source. If that schedule is not set, the default occupancy is continuously occupied.

Setting the local schedule

About this task:

A weekly occupancy schedule with up to four occupancy events for each day can be set locally on
the TEC and operate independently of a supervisor. To set the schedule:

1. See Selecting schedule source to ensure the schedule source is set to Local.

2. Press the Menu icon.

3. Press Scheduling.

4. Press Set Schedule.

5. Select the days to which the schedule should apply. Note that if events are already set for the
selected days, they appear in the corresponding event box. If any events conflict between
selected days, an asterisk appears in the event box. See Figure 24.

6. Select the Occupancy Status icon for the event. See Figure 25.

Important: Internally, the TEC3000 uses a BACnet schedule where daily schedules are
independent of the previous and next days. The default occupancy of the TEC3000 from the
factory is set to Occupied. As a result, a daily event at 12:00 AM must be scheduled if you do
not want the controller to transition to Occupied Mode at midnight.

1. Press the Menu icon.

2. Press Scheduling

3. Press Schedule Options.

4. Press Manual Occ Mode and select Occupied, Unoccupied, or No Override.

5. Press Save and the back arrow to return to the previous screen.

This option is also exposed to the BAS through the point OCCOVRD-MODE.

Enabling optimal start

About this task:

The TEC supports an advanced optimal start algorithm. The algorithm works in conjunction with a
local schedule to pre-heat or pre-cool the zone before scheduled occupancy periods begin, in order

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide38

to bring the zone to the desired occupied setpoint when the scheduled occupancy period begins.
Occupant comfort is ensured while automatically minimizing energy usage. This algorithm creates
a model of the zone being controlled and automatically determines when to start the equipment
before the scheduled transition to Occupied. The start time automatically adjusts daily to minimize
the time between reaching setpoint and entering Occupied state.

Note: Optimal Start does not work when the schedule source is set to External.

To enable this feature:

1. Press the Menu icon.

2. Press Scheduling.

3. Press Schedule Options.

4. Press Optimal Start Enable and select Yes.

5. Press Save and the back arrow to return to the previous screen.

Enabling the motion sensor (TEC3x12, TEC3x13 Models)

About this task:

By default on models with integral motion sensing capability, the motion sensor is enabled with a
default timeout of 15 minutes from the last detection of motion in the zone. On models without an
integrated sensor, the default timeout is still 15 minutes, but it only is applied when one of the two
configurable binary inputs is set to be a motion sensor (see Configurable binary inputs for informa­tion on configuring the binary inputs). To disable motion sensing capabilities, set the Motion Sensor
Timeout to 0 minutes. See Table 8 to view the available setpoints. See Table 13 to view the setpoint

4. Press Motion Sensor Timeout and adjust accordingly.

5. Press Save and the back arrow to return to the previous screen.

PID/PRAC+ automatic control tuning

About this task:

The TEC3000 features advanced proportional-integral-derivative (PID) control algorithms to max­imize control performance while minimizing excessive cycling and wear on the equipment. PID is
used in conjunction with a Multi-Stage Controller (MSC) for all occupied and standby control.
Additionally, the PID features Johnson Controls proprietary PRAC+ (Pattern Recognition Adaptive
Control) automatic tuning, which continuously tunes the controller parameters to automatically
optimize the control performance to match the equipment and zone. By default, PRAC+ is enabled
and immediately begins to tune. To reset tuning at any time to the factory defaults:

1. Press the Menu icon.

2. Press Setup.

3. Press General Control Setup.

4. Press Tuning.

5. Press Reset PID Tuning and select Yes.

6. Press Save and the back arrow to return to the previous screen.

39TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide

PRAC+ automatic tuning can also be disabled. When disabled, the controller parameters remain at
their last values until automatic tuning is re-enabled. To disable automatic tuning:

1. Press the Menu icon.

2. Press Setup.

3. Press General Control Setup.

4. Press Tuning.

5. Press Temp Control Setup.

Configurable binary inputs

The thermostat controller supports up to two configurable binary inputs (BIs) that you can use to
add additional features to the system. You can access Configurable Binary Inputs through Setup >
Inputs. Both BIs can be configured to support the following options:

• Disabled—Sets the binary input to an unused state. When disabled, you can use the binary input

for monitoring-only without affecting the thermostat functionality.

• Open Window—Sensor to shut down control if a window is opened. The controller disables

control 60 seconds after detecting an opened window.

• Open Door—Works in conjunction with the Motion NO/Motion NC sensor to control occupancy

• Fan Lock—Air Proof switch input to shut down control if no airflow is detected within 10 seconds

of turning the fan on. Fan Lock must be manually reset from the Faults menu.

• Service—Input from the equipment to display a service warning on the thermostat

• Dirty Filter—Input from the equipment to display a dirty filter fault on the thermostat

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide40

• Motion NC—External motion sensor with a closed contact output when no motion is detected

• Motion NO—External motion sensor with an open contact output when no motion is detected

• Temp Occ—Trigger to place controller into Temporary Occupancy mode

• Occupancy—Direct override of Occupied and Unoccupied

• Supply Fan Status—Input from the equipment to display a Supply Fan Fault. When Fan Alarm
Action is set to Shutdown and the Supply Fan Fault is active, the TEC3000 disables the fan,
heating, and cooling. When the Fan Alarm Action is set to Enable and the Supply Fan Fault is
active, the TEC3000 allows the fan, heating, and cooling to operate during the Supply Fan Fault.

Setting both BIs to the same function is supported for all except Occupancy, Fan Lock, Open Door,
and Open Window. If both BIs are set the same for those four, BI2 is ignored and only BI1 is used.

The Open Door option works in conjunction with a motion sensor, either built into the TEC or
connected to another BI configured for Motion NO/NC mode. When the door is open, motion
detected by the sensor is ignored. Note that opening the door does not stop an Occupied period
started by the motion sensor prior to opening the door.

Aux control

About this task:

The TEC has an auxiliary output that can be configured to operate in a few different ways. The Aux
Mode supports the following options:

• Not Used—Output is always off

• Occupied NO—Output is normally open, but closes when occupied

• Occupied NC—Output is normally closed, but opens when occupied

• Occupied Fan NO—Output is normally open, but is closed when occupied with the fan running

• Occupied Fan NC—Output is normally closed, but is open when occupied with the fan running

41TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide

• On—Output is turned on (relay closed), used by a BAS to directly control the AUX output

• Off—Output is turned off (relay open), used by a BAS to directly control the AUX output

To set the Aux Mode:

1. Press the Menu icon.

2. Press Setup.

3. Press General Control Setup.

4. Press Aux Mode and set accordingly.

5. Press Save and the back arrow to return to the previous screen.

This option is also exposed to the BAS through the point AUX-MODE.

When the Reheat installed parameter is set to True, the Aux output is used for Reheat Output. The
setting for the Aux Mode is ignored when reheat is enabled.

Commissioning mode

About this task:

The thermostat controller has a built-in commissioning mode, which is designed to allow you to
quickly test equipment wiring and functionality. Commissioning mode temporarily disables the con­trol logic, and allows you to manually command any individual output. Commissioning is designed
to be the last step of the installation process after configuring the controller for the equipment
being controlled, and the available options in commissioning mode are dependent on the controller
configuration. To enter commissioning mode:

1. Press the Menu icon.

2. Press Setup.

3. Select Commissioning.

4. Confirm that the selection was intentional. (The control is overridden upon selecting Confirm).

Individual outputs can be commanded through this interface. For binary outputs, the options are
Off or On; for analog outputs, they can be commanded from 0 to 100%. Whenever a control output
is turned on, the fan is engaged for safety purposes. To command an output from the Commission­ing menu:

1. Select the output to command. Adjust the value to the desired output and press Save. The
output immediately changes to that value.

2. Restore the value to the original setting and press Save once again to complete testing that
output.

Pressing the back icon from the main commissioning menu or allowing the menu system to time
out and return to the home screen ends commissioning and puts the control logic back in control of
the outputs.

Configurable analog inputs (AIs)

The thermostat controller supports up to three configurable AIs that can be used to add different
features to the system. The configuration menu can be accessed through Setup > Input Setup. All
AIs can be configured to support the following options:

• Relative Humidity—Sets up the AI to accept a 0-10 VDC input when connected to a humidity

sensor.

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide42

• Remote Zone Temperature—Sets up the AI to accept a resistive input when connected to one of
the six supported types of temperature sensors.

Carbon Dioxide—Sets up the AI to accept a 0-10 VDC input when connected to a CO2 sensor.

•

• Damper Feedback—Sets up the AI to accept a 0-10 VDC input when connected.

• Outdoor Air Temperature—Sets up the AI to accept a resistive input when connected to one of
the six supported types of temperature sensors.

• Supply Air Temperature—Sets up the AI to accept a resistive input when connected to one of the
six supported types of temperature sensors.

Configuring the AIs

1. Connect the required sensors to the analog inputs.

2. Press the Menu icon.

3. Press Setup.

4. Press Input Setup.

5. Press AI1 Input Selection and select the sensor that is connected to RSEN. If the selected

sensor is a Remote Zone Temperature, Outdoor Air Temperature, or Supply Air Temperature
sensor, the thermostat restarts.

6. Do one of the following after the restart based on the type of sensor you are configuring:

- If the selected sensor is a temperature sensor, do the following:

i. Press Menu > Setup > Input Setup > AI1 Input Setup and select the temperature

sensor that is connected to RSEN.

ii. Press Menu > Setup > Input Setup > AI1 Offset and select the temperature offset as

needed for the sensor connected to RSEN. The options are -5°F to 5°F or -2.8°C to

2.8°C.

- If the selected sensor is a Relative Humidity, Carbon Dioxide, or Damper feedback sensor, the
Input Setup is automatically set to 0-10 VDC. Press Menu > Setup > Input Setup > AI1 Offset
and select the offset needed for the sensor connected to RSEN. The options are -15% to 15%
for Relative Humidity, -200 ppm to 200 ppm for Carbon Dioxide, and -15% to 15% for Damper
Feedback.

7. Configure the analog inputs RSEN and COS by following the same steps to set up AI1 Input
Selection, AI1 Input Setup, AI1 Offset, AI2 Input Selection, AI2 Setup, and AI2 Offset.

8. Complete steps 1 -7 to re-configure the respective AI if you have to change the sensor
connected to any of the AIs. When the setup of AI1 Input Selection and AI2 Input Selection
changes from resistive type (Remote Zone Temperature and Outdoor Air Temperature) to 0-10
VDC type (Relative Humidity and Carbon Dioxide) or vice-versa, the thermostat restarts.

Networked sensors

The TEC3000 supports sensor values supplied over a network connection. For the TEC3000 to
consider the value as reliable, the value must be written to the NET- Override network point at least
every 15 minutes. The following table provides a list of point descriptions and the suggested write
interval ranges.

43TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide

Table 12: Point descriptions and suggested write interval ranges

Name Description Suggested write interval range

NET-OAT Network Override Outdoor Air Temperature 15 minutes at maximum
NET-OAH Network Override Outdoor Air Humidity 15 minutes at maximum
NET-SAT Network Override Supply Air Temperature 30 seconds to 2 minutes
NET-ZNH Network Override Zone Humidity 5 minutes to 15 minutes at

maximum
NET-ZNT Network Override Zone Temperature 15 seconds to 2 minutes
NET-OCC Network Override Zone Occupancy 15 minutes at maximum

Availability of AIs

For TEC3x1x-1x-xxxx models, only the RSEN and COS inputs are available for connection.

Priority for configurable AIs

You cannot set any two AIs to the same function or sensor type for any of the inputs. If two or more
AIs are configured as the same, the first configured input is used and the others are ignored. For
example, if RSEN and COS are both configured as Relative Humidity, only RSEN is used and COS is
ignored.

Priority for overall sensors data sources

The TEC3000 supports various sources of sensor data for use in control or display, including internal
sensors, remote sensors (connected using an analog input), or network commanded sensors. The
TEC uses the highest priority connected input (network commands followed by remote sensors and
then internal sensors) for control and display. Not all sources are available for all sensors.

Network commands operate on a timeout basis. When a network point is written to by a supervisor,
the point becomes the highest priority for 15 minutes. If a new update is written within 15 minutes,
the timer is restarted for another 15 minutes.

Available fault diagnostics

• Supply Fan Faults—The TEC3000 supports a configurable Supply Fan Status feedback input that
turns on when the Supply Fan Status does not match the Supply Fan Command, and can be
configured to disable heating, cooling, and fan commands. The alarm delay is adjustable through
the Fan Alarm delay setting. If the delay is set to 0 or the binary input is not defined, this feature
becomes disabled.

• Supply Fan Runtime—The TEC3000 supports setting runtime limits on the supply fan command.
When the limit is exceeded, an alarm turns on. This feature is intended to be used as a
maintenance reminder. Setting the runtime limit to 0 disables this feature.

• Supply Air Temperature Diagnostics—The TEC3000 supports diagnostics when you installed a
Supply Air Temperature. The TEC3000 monitors the supply air. If you call for cooling or heating
and the temperature does not fall or rise by at least the supply air temperature alarm offset
value within the supply air temperature alarm delay, an alarm is generated. If the monitoring
occurs while cooling, a cooling ineffective alarm is generated. If the monitoring occurs while
heating, a heating ineffective alarm is generated. If you set the supply air temperature offset
value set to 0, this alarm is disabled.

TEC3000 Series On/Off or Floating Fan Coil Thermostats Installation Guide44

• Zone Temperature Alarm—When enabled, the user can set a low and high temperature alarm;
and if the zone temperature rises or falls below those limits, an alarm is generated.

• Trends—Built-in trends exist for many of the inputs and outputs for the TEC3000. These trends
are viewable at the TEC. The analog graph displays data in 15-minute increments over the
previous 24 hours or a table with the last 25 data points. Binary trends display 25 samples taken
at every change of state.
