Controllers Installation Guide

ApplicationsThe TEC3000 Series Single- or Two-Stage EconomizerThermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or N2 networked devices.Wireless networked models of the TEC3000 SeriesThermostat Controller are also available. Series Single- orTwo-Stage Economizer Thermostat Controllers providecontrol of the following:• Unitary rooftop units (RTUs)• Unitary RTUs with economizers• Unitary heat pumps• Unitary heat pumps with economizers• Unitary RTUs with hot gas reheat• Unitary RTUs with hot gas reheat and economizersThe networked models feature a field-selectableBuilding Automation System (BAS) BACnet MS/TP or N2communication capability that enables remote monitoringand programming for efficient space temperature control.The wireless models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that enablescommunication with a building automation system (BAS).The wireless models (TEC30xx-xx-000) are compatibleonly with the WNC1800/ZFR182x Pro Series Wireless FieldBus System that enables communication with a buildingautomation system (BAS). The new wireless models(TEC31xx-14-000) are compatible only with WRG1830/ZFR183x Pro Series Wireless Field Bus System. All modelsinclude a USB port configuration that reduces installationtime to allow simple backup and restore features from aUSB drive, which enables rapid cloning of configurationbetween similar units.Some models have occupancy sensing capability built intothe device. These thermostat controllers maximize up to30% energy savings in high-energy usage commercialbuildings, such as schools and hotels, during occupiedtimes by using additional standby setpoints.All models feature an intuitive onboard touchscreenUI with backlit display that makes setup and operationquick and easy. Only the single-speed fan configuration issupported for fan coil equipment types.All models contain a build-in humidity sensor to supportdehumidification on RTUs with hot gas reheat and RTUswith auxiliary dehumidifier installed. When no heatingis required, the thermostat controller monitors thespace humidity and activates dehumidification control asnecessary. Heat, reheat or both are used as required toprevent over-cooling while achieving humidity setpointand maintain the space temperature.

Important: The TEC3000 Series ThermostatController is intended to provide an input toequipment under normal operating conditions.Where failure or malfunction of the thermostatcontroller could lead to personal injury or propertydamage to the controlled equipment or otherproperty, additional precautions must be designedinto the control system.

InstallationParts included• One TEC3000 Series Thermostat Controller with integral

mounting base• One installation instructions sheet

Location considerationsFor networked models, locate the TEC3000 SeriesThermostat Controller:• On a partitioning wall, approximately 5 ft (1.5 m) above

the floor in a location of average temperature, to allowfor vertical air circulation to the TEC

• Away from direct sunlight, radiant heat, outside walls,outside doors, air discharge grills, stairwells, and frombehind doors

• Away from steam or water pipes, warm air stacks,unconditioned areas (not heated or cooled), or sourcesof electrical interference

• In a clear path between the integrated passive infrared(PIR) occupancy sensor, if equipped, and the space itmonitors

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 pathbetween the TEC3000 and other wireless devices isdirect as possible. Line of sight is desirable but notrequired. See Table 1 and Table 2 for the recommendedand maximum distances.

• Away from metal and large solid obstructions, thatincludes equipment rooms and elevator shafts andconcrete or brick walls, between the TEC3000 andthe ZFR182x or ZFR183x Router/Repeater or ZFR ProCoordinator Radio

• Within range of two or more wireless devices on thesame PAN. Redundancy in the layout provides the bestreliability in wireless installations

• At least 20 ft (6 m) from a microwave ovenFor integrated PIR models, make sure that the thermostatcontroller is located centrally, where occupant movementis frequent. Ensure that the unit is not blocked by a plastictamper resistant enclosure (such as the GRD10A-608). Theplastic enclosure blocks the occupancy sensing capability.

The use of insulating foam pads is necessary forinstallations where wiring passes through the wall to thethermostat.For wireless models, the effective transmission range anddistance for indoor applications vary because of wirelesssignal absorption and reflection due to metal obstructions,walls or floors, and furniture that is found in buildinginteriors.Table 1: Indoor line-of-sight transmission rangesZFR182x

The TEC supports three methods of determiningeconomizer availability. These are Dry Bulb, SingleEnthalpy, and Dual Enthalpy, in increasing order ofaccuracy. To run an economizer, outdoor air temperature(OAT) is required to run in Dry Bulb mode. This can beprovided by connecting a sensor to the OAT input on theTEC. It also can be provided by writing to NET-OAT froma Building Automation System (BAS), which overridesthe internal sensor. If Outdoor Air Humidity (OAH) isalso provided by writing to NET-OAH, the dual enthalpymethod is used to determine if economizer cooling shouldbe used.All network overrides to the TEC work on a timeout basis.If the value is written to, it remains active as long as theBAS writes a new value within 15 minutes of the first one.If the 15-minute timeout occurs without getting any datawritten, 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 OAEnthalpy Setpoint, respectively. The TEC ships with defaultvalues set, but depending on climate it may be necessaryto change these. To access these values, complete thefollowing steps:

1. Press the Menu icon.2. Press Setup.3. Press Equipment Setup.4. Press Economizer.5. Press Dry Bulb Setpoint or Outdoor Enthalpy

Setpoint and adjust according.6. Press Save and the back arrow to return to the

Setting the Control modeAbout this task:The Control Mode informs the controller to run in Coolingonly, Heating only, or Automatic mode, based on thetemperature in the zone relative to the heating andcooling setpoints. Control Mode does not overrideequipment lockouts or changeover. To set the ControlMode, complete the following steps:

1. Press the Menu icon.2. Press Setup.3. Press General Setup.4. Press Control Mode and select Cooling, Heating,

or Auto as preferred.5. Press Save and the back arrow to return to the

previous screen.

Setting the Fan modeAbout this task:The Fan Mode informs the controller how to handlethe fan. There are two options for fan configuration: aFan Mode available to the installer through the menusystem, and a fan override available as an option to theend user from the Fan icon on the home screen. SeeCustomizing the home screen for information on enablingand disabling end-user controls. The Fan Mode availableto the installer depends on the fan type. The followingoptions are provided for single-speed fans:• On—Fan is continuously on• Auto—Fan cycles on demand with the controller

entering cooling, heating, or dehumidification modes• Smart—Fan cycles on demand with the controller

entering cooling or heating modes during unoccupiedperiods but is continuously running during occupiedand standby periods

The Fan Override icon on the home screen dependson the fan type. The following options are provided forsingle-speed fans:• On—Overrides the fan to be continuously on• Auto—Follows the behavior set as Fan Mode• Quiet—Follows the behavior set as Fan Mode, but

prevents the fan from ever going above minimumspeed. The Quiet option has no effect on equipmentwith single-speed fans.

To set the Fan Mode, complete the following steps:

1. Press the Menu icon.2. Press Setup.3. Press General Setup.4. Press Fan Mode and select On, Auto, or Smart.5. Press Save and the back arrow to return to the

previous screen.

Configuring the zone space orequipment sizeAbout this task:With non-binary outputs, the TEC3000 defaultconfiguration is to have a slower temperature responsefor larger zones with normal-sized equipment. Ininstallations with small zones and oversized equipment,set the Equipment Size parameter to Oversized.To set the Equipment Size parameter, complete thefollowing steps:

1. Press the Menu icon.2. Press Control Setup.3. Press Tuning.4. Use the up and down arrows to navigate to

Equipment Size.5. Press Equipment Setup and select Oversized.6. Press Save and the back arrow to return to the

previous screen.

Temperature setpointsAbout this task:The thermostat controller provides a flexible setpointconfiguration to give power to the building owner whilebeing easy to use by the occupant. In addition to a simpleup/down offset adjustment on the home screen for theoccupant, there are six temperature setpoints on the TEC.The six temperature setpoints are Cooling and Heatingsetpoints for Occupied, Unoccupied, and Standby modes.To set these setpoints, complete the following steps:

1. Press the Menu icon.2. Press Setpoints and then Temperature.3. Select the setpoint to adjust and change as

preferred.4. Press Save and the back arrow to return to the

previous screen.Note: The TEC enforces a 2-degree deadbandbetween heating and cooling setpoints. If asetpoint violates this standard (for example,cooling setpoint is set to 70 with a heatingsetpoint already set to 70), the opposingsetpoint is modified to comply with thisdeadband (in the previous example, theheating setpoint would automatically change to68).

ResultThe occupant has access to an up/down adjustment fromthe home screen. This adjustment applies a fixed offset(+/-) to the currently active setpoint, and this offset holdsuntil the occupancy state of the controller changes. Ifthe user taps the setpoint on the home screen, the iconinverts and displays white text on a black icon. The offsetis held throughout all occupancy periods. For example,if the TEC is cooling in Occupied mode to an occupiedcooling setpoint of 72 and you raise the setpoint 2degrees to 74 from the home screen and then select hold,then the +2 degree offset persists through an occupancychange. If the occupancy then changes to unoccupied,


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

Table 8: Setpoint operation

Mode ofsetpointoperation

Details

Occ SetpointSelect =SetpointOffset andHeat CoolSetpointMode =IndividualSetpoints

This is the default mode and the originalmode of operation that the TEC wasreleased with (the next three modes arenew). In this mode, the TEC has a heatingsetpoint and a cooling setpoint. There is acommon Setpoint Offset (warmer/cooleradjust) that applies to each setpointsimultaneously. The range of setpointadjustment is two-fold:• There are large constant ranges

bounding the individual heating andcooling setpoints.

• There is also a smaller configurablerange limit set to the Setpoint Offsetpoint (Control Setup > General > MaxSetpoint Offset).

Occ SetpointSelect = Minand MaxSetpointsand HeatCoolSetpointMode =IndividualSetpoints

In this mode, the TEC has a heatingsetpoint and a cooling setpoint. Eachsetpoint has a configurable range(Setpoints > Temperature > Min CoolingSetpoint, Max Cooling Setpoint, MinHeating Setpoint, and Max HeatingSetpoint). The configurable range valuesare bounded by the larger constantbounds used in Setpoint Offset mode andare constrained in the following manner:Min must be below Max and Heatingmust be below Cooling, so in order fromleast to greatest, the values are: MinHeating Setpoint, Max Heating Setpoint,Min Cooling Setpoint, and Max CoolingSetpoint.

Occ SetpointSelect =SetpointOffset andHeat CoolSetpointMode =CommonSetpoint

In this mode, the TEC has one setpoint,Common Setpoint, for heating andcooling. There is also a common SetpointOffset (warmer/cooler adjust) that onlyapplies to Common Setpoint. Otherwise,this setting works the same as when OccSetpoint Select = Setpoint Offset and HeatCool Setpoint Mode = Individual Setpoints.

Occ SetpointSelect = Minand MaxSetpointsand HeatCoolSetpointMode =CommonSetpoint

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


Configuring occupancyTo adapt to nearly any application, the TEC3000 controllersupports 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 inputOccupancy is determined using a top-down decisionmatrix as shown in Table 9.Enumerations may not match the TEC3000 SeriesNetworked and Wireless Single- or Two-Stage EconomizerThermostat Controllers Installation Guide (LIT-12013163)and the TEC3000 Series Field-Selectable BACnet MS/TP orN2 Networked Thermostat Controllers Technical Bulletin(LIT-12011956) for NAE releases prior to 7.x.

schedule is not Occupied.3 When triggered by a BI configured for Temp Occ, the input is ignored when the schedule is Occupied, the Manual Occupancy Mode

is not No Override, or an Occupancy BI is configured.4 Built-in occupancy sensing (PIR) or BI configured for Motion NO or Motion NC.5 Not Set occurs when no events are scheduled through the local scheduler, or the schedule source is set to Schedule and the

Schedule is writing Not Set as the schedule.


Selecting schedule sourceScheduling (for networked models)The TEC3000 Thermostat Controller can operate as astand-alone unit with an internal schedule or scheduledwith an external schedule. The OCC-CONFIG object setsthe method used for scheduling.If the OCC-CONFIG is set to External, the NET-OCC objectis used to control the unit externally.If the OCC-CONFIG is set to Schedule, the internalschedule commands the LOCAL-OCC object, which setsthe Occupancy Schedule command.

Note: If you do not have a schedule in theSchedule object and you have the OCC-CONFIGset to Schedule, you can control the unit with theLOCAL-OCC object externally; however, we donot recommend this method. See Table 10 forscheduling information.

Once the Occupancy Schedule command is set, thesettings shown in the occupancy determination tabledetermine the effective occupancy. See Table 9.Table 10: BAS objects for schedulingOCC-CONFIG LOCAL-OCC

Scheduling (for all models)About this task:The occupancy schedule comes from either the weeklyscheduler built into the TEC or as an input from theBAS. The Schedule Source must be selected to tell thecontroller where to read the occupancy source from. Toselect the schedule source, complete the following steps:

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 pointOCC-CONFIG. If BAS is configured as the occupancysource, map the point NET-OCC in and write to thatpoint to control the schedule remotely. If the supervisorgoes offline (as identified by the network icon goingaway on the home screen of the TEC), the control logic

automatically falls back to the local schedule as theoccupancy source. If that schedule is not set, the defaultoccupancy is continuously occupied.

Setting the local scheduleAbout this task:A weekly occupancy schedule with up to four occupancyevents for each day can be set locally on the TEC andoperate independently of a supervisor. To set theschedule, complete the following steps:

1. See Selecting schedule source to ensure theschedule 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.

If events are already set for the selected days,they appear in the corresponding event box. If anyevents conflict between selected days, an asteriskappears in the event box. See Figure 16.

6. Select the Occupancy Status icon for the event. SeeFigure 17.

Important: Internally, the TEC3000 uses aBACnet schedule where daily schedules areindependent of the previous and next days.The default occupancy of the TEC3000 fromthe factory is set to Occupied. As a result, adaily event at 12:00 AM must be scheduled ifyou do not want the controller to transition toOccupied Mode at midnight.

Overriding the Occupancy modeAbout this task:The TEC supports a manual override of all other schedulesources (for example, Schedule, Occupancy BI, andtemporary occupancy). To override the Occupancy Mode,complete the following steps:

1. Press the Menu icon.2. Press Scheduling3. Press Schedule Options.

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


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

Enabling optimal startAbout this task:The TEC supports an advanced optimal start algorithm.The algorithm works in conjunction with a local scheduleto pre-heat or pre-cool the zone before scheduledoccupancy periods begin, in order to bring the zoneto the required occupied setpoint when the scheduledoccupancy period begins. Occupant comfort is ensuredwhile automatically minimizing energy usage. Thisalgorithm creates a model of the zone being controlledand automatically determines when to start theequipment before the scheduled transition to Occupied.The start time automatically adjusts daily to minimize thetime between reaching setpoint and entering Occupiedstate.

Note: Optimal Start does not work when theschedule source is set to External.To enable this feature, complete the following steps:

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 (TEC3x31Models)About this task:On models with integral motion sensing capability, themotion sensor is enabled with a default timeout of 15minutes from the last detection of motion in the zone.On models without an integrated sensor, the defaulttimeout is still 15 minutes, but it only is applied when oneof the two configurable binary inputs is set to be a motionsensor. See Configurable binary inputs for information onconfiguring the binary inputs. To disable motion sensingcapabilities, set the Motion Sensor Timeout to 0 minutes.See Table 9 to view the available setpoints. See Table 14to view the setpoint values. To adjust the motion sensortimeout, complete the following steps:

Configurable binary inputsThe thermostat controller supports up to twoconfigurable binary inputs (BIs) that can be used to addadditional features to the system. Configurable BinaryInputs are accessed through Setup > Inputs. Both BIs canbe configured to support the following options:• Disabled—Sets the binary input to an unused state.

When disabled, you can use the binary input formonitoring-only without affecting the thermostatfunctionality.

• Open Window—Sensor to shut down control if awindow is opened. The controller disables control 60seconds 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 controlif no airflow is detected within 10 seconds of turningthe fan on. Fan Lock must be manually reset from theFaults menu.

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

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

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

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

• Temp Occ—Trigger to place controller into TemporaryOccupancy mode

• Occupancy—Direct override of Occupied andUnoccupied

• Supply Fan Status—Input from the equipment todisplay a Supply Fan Fault. When Fan Alarm Action isset to Shutdown and the Supply Fan Fault is active, theTEC3000 disables the fan, heating, and cooling. Whenthe Fan Alarm Action is set to Enable and the SupplyFan 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 not supported forOccupancy, Fan Lock, Open Door, and Open Window. Ifboth BIs are set the same for those four, BI2 is ignoredand only BI1 is used.The Open Door option works in conjunction with a motionsensor, either built into the TEC or connected to anotherBI configured for Motion NO/NC mode. When the dooris open, the sensor ignores detected motion. Openingthe door does not stop an Occupied period started by themotion sensor prior to opening the door.The polarity of the inputs are provided in Table 12.Table 12: Input polaritiesBIconfiguration

Press Menu > Setup > InputSetup > AI1 Offset and select the offsetneeded for the sensor connected to RSEN. Theoptions 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 SAT and OAT byfollowing the same steps to set up AI2 InputSelection, AI2 Input Setup, AI2 Offset, AI3 InputSelection, AI3 Setup, and AI3 Offset.

8. Complete steps 1 to 7 to re-configure therespective AI if you have to change the sensorconnected to any of the AIs. When the setup of AI1Input Selection, AI2 Input Selection, and AI3 InputSelection changes from resistive type (RemoteZone Temperature, Outdoor Air Temperature, andSupply Air Temperature) to 0 VDC-10 VDC type(Relative Humidity, Carbon Dioxide, and DamperFeedback) or the other way around, the thermostatrestarts.

Networked sensorsThe TEC3000 supports sensor values supplied over anetwork connection. For the TEC3000 to consider thevalue as reliable, the value must be written to the NET-Override network point at least every 15 minutes. Table13 provides a list of point descriptions and the suggestedwrite interval ranges.Table 13: Point descriptions and suggested writeinterval ranges

Availability of AIsFor TEC3x3x-1x-xxxx models, RSEN, SAT, and OAT inputsare available for connection.

Priority for configurable AIsYou cannot set any two AIs to the same function orsensor type for any of the inputs. If two or more AIs areconfigured as the same, the first configured input is usedand the others are ignored. For example, if RSEN, SAT, andOAT are all configured as Relative Humidity, only RSEN isused and SAT and OAT are ignored.

Priority for overall sensors data sourcesThe TEC3000 supports various sources of sensor datafor use in control or display, including internal sensors,remote sensors that connect using an analog input, ornetwork commanded sensors. The TEC uses the highestpriority connected input, which consists of networkcommands followed by remote sensors and then internalsensors, for control and display. Not all sources areavailable for all sensors.


Network commands operate on a timeout basis. Whena network point is written to by a supervisor, the pointbecomes the highest priority for 15 minutes. If thesupervisor writes a new update within 15 minutes, thetimer restarts for another 15 minutes.

Available fault diagnostics• Supply Fan Faults—The TEC3000 supports a

configurable Supply Fan Status feedback input thatturns on when the Supply Fan Status does not matchthe Supply Fan Command, and that you can configureto disable heating, cooling, and fan commands. Youcan adjust the alarm delay with the Fan Alarm delaysetting. If the delay is set to 0 or if you do not definethe binary input, this feature becomes disabled.

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

• Supply Air Temperature Diagnostics—The TEC3000supports diagnostics when you have a Supply AirTemperature installed. The TEC3000 monitors thesupply air. If you call for cooling or heating and thetemperature does not fall or rise by at least the supplyair temperature alarm offset value within the supplyair temperature alarm delay, an alarm generates.If the monitoring occurs while cooling, a coolingineffective alarm generates. If the monitoring occurswhile heating, a heating ineffective alarm generates. Ifyou set the supply air temperature offset value set to 0,this alarm disables.

• Zone Temperature Alarm—When enabled, the user canset a low and high temperature alarm; and if the zonetemperature rises or falls below those limits, an alarmgenerates.

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