Applications

The TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers are stand-alone and
field-selectable BACnet® MS/TP or N2 networked devices that 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.
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 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. Multiple fan configurations are supported for fan coil equipment types:

• 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).

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

For integrated passive infrared (PIR) models, be sure
that the thermostat controller is located centrally,
where occupant movement is frequent.

Use insulating foam pads for installations where
wiring passes through the wall to the thermostat.

Note: Allow for sufficient clearance to insert a USB
drive into the USB port.

IMPORTANT: Only connect memory devices to the USB port. Do not use it for charging external devices.

Installing the Thermostat Controller

1. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson Controls® T-4000-119 Allen-Head Adjustment Tool (order
separately) to remove the security screw if it is installed on the top of the thermostat controller cover as
illustrated in Figure 2.

2. Pull the top edge of the cover and open the thermostat controller as illustrated in Figure 2.

IMPORTANT: The cover is not secured on the bottom. Be careful not to drop the cover.

IMPORTANT: If you are installing more than one thermostat controller, keep track of which cover attaches to

which base.

IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid
damage to the electronic circuits of the thermostat controller.

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.

Notes:

• If you need to install the thermostat controller 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 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.

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 10. Before any outputs turn on, the controller must be
configured for the equipment connected. You need to start from the home screen to per form any of the following
tasks.

Screen Reset

The current screen returns to the home screen if the current screen is not touched for 3 minutes.

Selecting the Unit Type

There are three unit types. They are:

• 4-pipe—This unit type has both heating and cooling coils pl us a supply fan. This config uration can also be used
on configurations that are heating or cooling only.

• 2-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 conn ection of an analog sensor or an aquastat to a binary input. Based on th e
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. Th e TEC does n ot control the unit d elivering
the air. The logic needs to be part of another controller.

By default, the thermostat controller is configured for 4-pipe fan coil mode. To change to a 2-pipe or
Pressure-Dependent VAV mode:

1. Press the Menu icon.

2. Press Equipment Setup.

3. Press General.

4. Press Unit Type and select 2-pipe, 4-pipe, or VAV.

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 volta ge 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 bina ry output is off an d the voltage a t th e VSF outp ut is 0 V. When the
fan turns on, the FAN binary output turns on and the voltage at the VSF output begins controlling the fan. When the
VSF is configured for reverse acting mode (Start Voltage is above Full Sp eed Voltage), the VSF output goes to th e
lesser of 10 V and 1 V above the Start Voltage when the fan is turned off.

Configuring the Zone Space or Equipment Size - Floating Actuators, Multi-Speed Fans, and
Variable-Speed Fans Only

With non-binary outputs, the TEC3000 is configured by default 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:

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 to save and

to return to the previous screen.

Changeover

Pressure-Dependent VAV systems and 2-pipe fan coils require changeover detection in order to switch seasonal
operation between heating and cooling modes. Th e TEC supports the following methods for changeover:
automatic changeover using an analog sensor (thermistor), automa tic changeover using a bi nary switch, or remote
changeover from a BAS and manual changeover.

TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers with Dehumidification

Capability Installation Instructions

22

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 be low the
changeover setpoint and remains in cooling mode until the measur ed tempe rature has r isen 10 de grees above the
changeover setpoint.

To configure automatic changeover:

1. Press the Menu icon.

2. Press Equipment Setup.

3. Press Changeover.

4. Press Changeover Mode and select Auto.

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

6. Press to save and

to return to the previous screen.

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

1. Press the Menu icon.

2. Press Equipment Setup.

3. Press General.

4. Press Changeover.

5. Press Changeover Mode and select Heating or Cooling.

6. Press to save and

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 2-pipe/VAV systems without an automatic changeover, or on 4-pipe systems, you can use COS as a
monitor-only point for reading an analog sensor. By setting the controller in 4-pipe mode, or selecting Heating or
Cooling for Changeover Mode, the controller defaults to monitor-only mode for the COS and exposes the value to
the network as the supply temperature.

Dehumidification Control - Fan Coil Only

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

• 4-pipe fan coil

• 4-pipe fan coil with reheat

• 2-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 multi­speed or variable-speed fan is recommended.

Dehumidification operates when the zone humidity increases abo ve the zone humidity setp oint 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 multi-speed or variable-speed fan runs at the lowest possible speed to maximize
condensation and moisture removal across the cooling coil.

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

Temperature Setpoints

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:

1. Press the Menu icon.

2. Press Setpoints.

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

4. Press to save and

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 o pposing 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 Occup ied mode to an oc cupied 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 chang e. If the occupancy then changes to un occupied, with a setp oint
of 80 degrees, the effective setpoint is 82 degree s. 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, pre ssing 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 valu e ou ts ide 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 Figure 5.

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

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

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:

• 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.

In this mode, the TEC has one setpoint, Common Setpoint, for heating and cooling. There is
a configurable range for Common Setpoint, Min Setpoint, and Max Setpoint.

Configuring Occupancy

The TEC3000 controller supports a wide variety of occupancy sources to adapt to nearly any application.

• 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 6.

Selecting Schedule Source

Scheduling

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.

TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers with Dehumidification

Capability Installation Instructions

26

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 7 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 6.

1. The effective occupancy can be affected by other factors listed in Table 6.

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 Schedule.

3. Press Schedule Options.

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

5. Press to save and

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 occu pancy source. If that schedule is not set, the default
occupancy is continuously occupied.

Setting the Local Schedule

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 Schedule.

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 18.

6. Select the event to be set. See Figure 18.

7. Set the Occupancy to Not Set, Occupied, Unoccupied, or Standby and press Save.

IMPORTANT: Internally, the TEC 3000 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.

Enabling Optimal Start

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 to bring the zone to the desired
occupied setpoint when the scheduled occupan cy p er iod b egins. Occu pan t comfort is en sure d while au to matically
minimizing energy usage. This algorithm creates a model of the zone being cont rolled 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 Schedule.

3. Press Schedule Options.

4. Press Optimal Start Enable and select Yes.

5. Press to save and

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 se nsing
capabilities, set the Motion Sensor Timeout to 0 minutes. See Table 6 to view the available setpoints. See Table 10

PID/PRAC+ Automatic Control Tuning

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 Control Setup.

Configurable Binary Inputs

The thermostat controller supports up to two configurable binary inputs (BIs) that can be used to add additional
features to the system. Configurable Binary Inputs are accessed through Settings > Control 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 second s

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

• 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.

Aux Control

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

• 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 Control Setup.

3. Press General.

4. Press Aux Mode and set accordingly.

5. Press to save and
This option is also exposed to the BAS through the point AUX-MODE.

to return to the previous screen.

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

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. Select Commissioning.

3. 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 ou tp ut immed iately

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.

Sensor Priority

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 se nsors) 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 up date 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 have a Supply Air

Temperature installed. 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.

• Zone Tempera tu re Alarm—When enabled, the user can se t a low and high temperature alarm; and if the zone

temperature rises or falls below those limits, an alarm is generated.

• Trends—Built-in tr ends exist for many of the inputs and outputs for the TEC3000. These tren ds 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.

The staged equipment shuts off

above the cooling setpoint or below
the heating setpoint when the PID
is running on the TEC. If the unit is
in On/Off Control mode, this does
not apply.

The staged equipment cycles too
rapidly or too slowly when the PID
is running on the TEC.

The controller provides an error
when trying to upgrade firmware.

The TEC3000 zone temperature
does not change fast enough
compared to the measured zone
temperature from a verification
device (a calibrated sensor).

The 2-pipe fan coil/VAV system
does not have a changeover
sensor and switch connected, or
the sensor/switch has failed.

The changeover temperature is
sensing a hot supply, but the
controller is requesting cooling.

Changeover temperature is
sensing a cold supply, but the
controller is requesting heating.

The Control Mode is set to
Cooling Mode, but the controller
is requesting heating.

The Control Mode is set to
Heating Mode, but the controller
is requesting cooling.

The PID control algorithm
minimizes overshoot and energy
usage for the particular
equipment and zone, and may
cycle the equipment prior to
reaching setpoint.

The control band around the
setpoint is determined by the
minimum on/off times and is set
incorrectly for the equipment,
zone, or user preference. There
is a tradeoff between reduced
control band size and increased
energy usage and equipment
wear from increased cycling.

The firmware on the USB drive is
below the minimum required
version.
Error code 1025.

The TEC3000 is configured by
default for larger spaces with
normal-sized equipment when a
proportional device is active.

1. Check the wiring of the supply temperature
sensor/switch.

2. Verify that the changeover is set up correctly
for the type of sensor attached (sensor or
switch).

1. Verify that the supply is not in heating mode. If
it is, nothing can be done from the TEC.

2. Check the wiring of the supply temperature
sensor or switch.

3. Check the placement of the supply
temperature sensor or switch.

4. Verify that the changeover is set up correctly
for the type of sensor attached (sensor or
switch).

1. Verify that the supply is not in cooling mode. If
it is, nothing can be done from the TEC.

2. Check the wiring of the supply temperature
