Applications

The TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or N2 networked devices that provide control of the following:

• unitary rooftop units (RTUs)

• unitary RTUs with economizers

• unitary RTUs with heat pumps

• unitary RTUs with economizers and heat pumps 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. Only the single-speed fan configuration is supported for fan coil equipment types.

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 blessur es ou d'endommager l'équipe ment contrôlé ou un autre équipement, la conception du système de con tr ôle 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 Contr oller with integral mounting base

• one installation instructions sheet

Location Considerations

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.

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, then the single enthalpy method is used to determine if economizer cooling should be used. Finally, if Zone Humidity (ZNH) is also provided by writing to NET-ZNH, then the dual enthalpy method is used to determine if economizer cooling should be used.

to return to the previous screen.

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:

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 desired 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 Table 5.

Table 5: Setpoint Operation

Mode of Setpoint

Details

Operation

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

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

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 range s bounding the individual heating and cooling setpoints.

• There is also a smaller co nfigurable 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.

Mode of Setpoint

Details

Operation

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

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 screen while unoccupied)

• 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.

TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

Page 21

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 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 can come 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.

TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

Page 22

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.

6. Select the event to be set.

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

to return to the previous screen.

Enabling the Motion Sensor (TEC3x31-00-000 Models)

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 to view the setpoint values. To adjust the motion sensor timeout:

1. Press the Menu icon.

2. Press Schedule.

3. Press Schedule Options.

4. Press Motion Sensor Timeout and adjust accordingly.

5. Press to save and

to return to the previous screen.

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. For units configured with two sta ges of heating or cooling, 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.

3. Press Tuning.

4. Press Reset PID Tuning and select Yes.

5. Press to save and

to return to the previous screen.

TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

Page 25

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

1. Press the Menu icon.

2. Press Control Setup.

3. Press Tuning.

4. Press Temp Control Setup.

5. Select Manual PID T uning (o r any optio n listed in Table 8). PID tuning is active with the Automatic PID Tuning

and Deadband Override parameters.

6. Press to save and

to return to the previous screen.

As a result of disabling PRAC+ Auto Tuning, you have access to different types of manual tuning that allows modifications of tuning parameters listed under Control Setup > General in Table 10.

Note: For more details on PID/PRAC+ Automatic Control Tuning, refer to the Controller Tool Help (LIT-12011147).

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 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

• 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.

TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

Page 26

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: Opening the door does not stop an Occupied period started by the motion sensor prior to opening the door. The polarity of the inputs are provided in Table 9.

1. Configurations that support both BIs configured for the same feature of the action that occurs when either

of the BIs enter that state.

Note: Supply Fan Status and Fan Lock are not compatible with each other. The TEC3000 only co ntrols one fan so it cannot accept feedback from two fan sources. When configuring BI-1 and BI-2, choose either Supply Fan Status or Fan Lock, but not both.

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

to return to the previous screen.

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

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. Th e outp 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 supp ly 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 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 tren ds exist for many of the inputs and o utputs for the TEC3000. These trends a re 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.

Status of Cooling Unavailable despite being above cooling setpoint, or with a status of Heating Unavailable despite being below the setpoint.

The heat pump does not sequence properly.

The heat pump heats when it should be cooling, and cools when it should heat.

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 zone space temperature increases or decreases too much when the unit is active in unoccupied mode.

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

The outdoor air temperature is too warm for heating or too cold for cooling.

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 Number of Compressors set to Not Used and the controller is requesting cooling, or Number of Heating Stages is set to Not Used.

The heat pump requires traditional wiring (Y1, Y2, W1, W2, and G) and handles the reversing valve internally, but Heat Pump Supported is set to Yes.

The heat pump requires thermostat to control the reversing valve (Y1, Y2, O/B, and G) but the Heat Pump Supported is set to No.

Reversing Valve polarity is incorrectly set.

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 heating and cooling equipment are too big for the unoccupied space.

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

1. If Cooling and Heating Lockout Setpoints are inadequate, adjust the setpoints.

2. Wait for the outdoor conditions to be favorable for heating or cooling.

Change the Control Mode to Auto or Heating.

Change the Control Mode to Auto or Cooling.

Adjust the number of compressors and number of heating stages to match the configuration of the unit.

Consult the equipment documentation to verify wiring configuration, then set Heat Pump Supported to No.

Consult the equipment documentation to verify wiring configuration, then set Heat Pump Supported to Y es.

Consult the equipment documentation to verify reversing valve polarity, then adjust the Reversing Valve Polarity menu option accordingly.

Expected behavior.

1. Veri fy tha t e qui pment minimum on/ off times are set correctly .

2. If the default deadband around the setpoint does not provide the desired temperature control, set Temp Control Setup to Deadband Override and set the Deadband parameter to the desired value.

Please use firmware version 3.0.2.xxxx or higher.

A reboot is required to clear the Firmware Mismatch fault that occurs.

Decrease the Unoccupied Off Delay parameter from 10 minutes to a more appropriate time for the equipment configuration.
