TEC Series BACnet® MS/TP Network Temperature and Humidity Controllers Technical Bulletin6
Product Overview
The technologically advanced TEC Series Temperature and Humidity Controllers
feature a Building Automation System (BAS) BACnet MS/TP communication
capability that enables remote monitoring and programming for efficient space
temperature control.
The TEC Series Temperature and Humidity Controllers feature an intuitive user
interface with backlit display that makes setup and operation quick and easy. The
controllers also employ a unique, Proportional-Integral (PI) time-proportioning
algorithm that virtually eliminates temperature offset associated with traditional,
differential-based controllers.
The TEC Series Temperature and Humidity Controllers are BACnet MS/TP
networked devices that provide control of:
• rooftop units (with or without economizers)
• heat pumps
• single- and multi-stage heating and cooling equipment
• humidification and dehumidification equipment
• two- or four-pipe fan coils
• cabinet unit heaters
• local hydronic reheat valves
• pressure dependent Variable Air Volume (VAV) equipment with or without
local reheat
• other zoning equipment using an on/off, floating, or proportional
0 to 10 VDC control input
Connecting the MS/TP Bus
To connect the MS/TP Bus:
1. Set the MS/TP address of the TEC Series BACnet MS/TP Network
Temperature and Humidity Controller per the engineering drawings and test
for bus voltage, polarity, and isolation prior to wiring the MS/TP Bus. See the
Com addr parameter in the MS/TP Bus Objects Tables to set the MS/TP
address for the controller.
Note: For TEC26x6, TEC26x7, and TEC2645 models, Pressing and
holding the UP/DOWN arrow keys simultaneously displays the MS/TP
address that is assigned. For TEC260x and TEC2613 models,
pressing and holding the YES/NO keys simultaneously displays the
MS/TP address that is assigned.
Note: For more details on wiring the MS/TP Communications Bus, refer to
the MS/TP Communications Bus Technical Bulletin (LIT-12011034).
2. Observe the polarity when connecting the bus wires to the controller.

TEC Series BACnet® MS/TP Network Temperature and Humidity Controllers Technical Bulletin 7
3. After the bus wires are connected to the first controller, continue in a
daisy-chained fashion to the next controller.
Note: The bus wiring must be twisted-pair lines. Do not run the bus wiring in
the same conduit as line voltage wiring (30 VAC or above) or other
wiring that switches power to highly inductive loads (such as
contactors, coils, motors, or generators).
The MS/TP Bus requires proper termination and biasing at each end of a segment
(a segment is a physically continuous length of wire). Because controllers are not
equipped with end-of-line termination, a Johnson Controls® MS-BACEOL-0
End-of-Line Terminator (ordered separately) or similar device is recommended to
provide this end-of-line termination. An end-of-line terminator is required if a
supervisory controller is not at the end of the segment. If a supervisory controller is
at the end of the segment, then the end-of-line terminator switch on the supervisory
controller must be set in the ON position.
Note: Refer to the controller product bulletin for end-of-line terminator ordering
information.
The controller should be configured for automatic baud rate detection. Do not
exceed the maximum number of devices allowed on a field bus. Be sure that the
wiring terminations are set correctly and that all communication wiring is
daisy-chained with no taps.
A small green light under the controller cover (on the left edge when facing the
controller) indicates the communications mode when the controller is operating.
The following blink codes may be seen:
•Short-Short-Long: Indicates that the baud rate is known and that
communication is active.
•Short-Short: Indicates that the controller is scanning for the correct baud rate
and that there is no communication.
•Off: Indicates that there is no power to the controller or that the MS/TP wiring
polarity is reversed.
•Long: Indicates that the MS/TP communication daughter board is the wrong
type for the main board.

MS/TP Controller Mapping
Preparation
Before mapping a TEC Series BACnet MS/TP Network Temperature and
Humidity Controller into an NAE:
1. Decide which point objects within the controller need to be mapped. Only map
the point objects that need to be viewed on a regular basis because excessive
mapping lowers system performance. Suggested point objects for mapping
include: Room Temp, Mode, Fan, Occupancy Command, Heating SP, Cooling
SP, Setback Heating SP, and Setback Cooling SP. In addition, alarm points may
be mapped if they are used, and other point objects may be mapped if required.
Use the Engineering view to examine infrequently used point objects.
Note: We recommend that all controller configuration parameters be set as
desired prior to mapping the objects into the controller. If any controller
configuration parameters are altered after the objects are mapped into the
controller, it is recommended that all objects be re-mapped. We also
recommend caution when mapping configuration parameters, as they
should only be mapped if the operator is fully familiar with their use.
2. Verify that a Field Bus is defined in the NAE. BACnet MS/TP devices attach to
a Field Bus. Refer to the BACnet MS/TP Integration with the NAE Technical
Bulletin (LIT-12011013) for instructions on how to define a Field Bus.
3. For Metasys® system software prior to Release 4.0, verify that a BACnet
Integration is defined for the Field Bus. The controllers are mapped as BACnet
devices under a Field Bus BACnet Integration. Refer to the BACnet Controller
Integration with NAE/NCE Technical Bulletin (LIT-1201531) for instructions
on how to define a BACnet Integration.
Note: For Metasys system Release 4.0 or later software, this step is not
required.
At this point, the controller (and the required point objects inside the controller)
can be mapped.
Adding a Controller
The controller must be added before its points can be mapped. To do this, select the
Field Bus or a folder under it (refresh the tree view, if required, to see a newly
added BACnet Integration) and choose Field Device from the Insert menu.
Note: For Metasys system software prior to Release 4.0, select the BACnet
Integration under the Field Bus (refresh the tree view, if required, to see a
newly added BACnet Integration) and choose Field Device from the Insert
menu.

TEC Series BACnet® MS/TP Network Temperature and Humidity Controllers Technical Bulletin 9
Assisted Definition using Auto Discovery is the easiest way to add a new
controller online; however, this method requires that the controller to be added is
connected and ready to communicate.
Device object names used with BACnet Communication must be unique to fully
satisfy the requirements of BACnet. The controller automatically selects a device
object name for itself using the format TEC26xx-aaa, where aaa designates the
address selected (from 004 to 127) on the MS/TP network. If this name needs to be
changed by writing a new one into the controller device object, that name change
should be done before any point objects are mapped. Be sure that the name of the
new controller being added to the NAE matches that of the controller itself. This
name goes into the Name field of the Object section on the Configuration tab of the
Configure step in the Insert Field Device Wizard.
Device object IDs used with BACnet communications must be unique to fully
satisfy the requirements of BACnet MS/TP network guidelines. The controller
automatically selects a device object ID for itself using the format mmaaa, where
mm is 72 for TEC26x7 models, 73 for TEC26x6 and TEC2645 models, and 76 for
TEC260x and TEC2613 models; and, aaa designates the address selected (from
004 to 127) on the MS/TP network (for example, 73004, 73005). If this ID needs
to be changed by writing a new one into the controller device object, that ID
change should be done before any point objects are mapped. Be sure that the ID of
the new controller being added to the NAE matches that of the controller itself.
This number goes into the Instance Number field of the Network section on the
Hardware tab of the Configure step in the Insert Field Device Wizard.
Adding Point Objects
The required point objects must be mapped under the controller device. To
accomplish this, select the controller device under the BACnet Integration (refresh
the tree view if required to see a newly added controller device) and choose Field
Point from the Insert menu.
Note: For Metasys system Release 4.0 or later software, select a Field Bus or a
folder under it.
Assisted Definition using Auto Discovery is the easiest way to add new point
objects online; however, this function requires that the controller that is to be
mapped is connected and ready to communicate. When mapping point objects, the
point type must match the BACnet object type (for example, AV, MV, BI), and the
point instance number must match the point BACnet instance number.
IMPORTANT: Because some of the objects may not directly correlate to a
previous version (TEC26xx-2), you must rediscover all point objects for the
TEC26xx-4 version. For detailed information on this mapping, see the MS/TP
Controller Mapping section of this document.

Troubleshooting
Table 2: Troubleshooting Details1
1. For common MS/TP troubleshooting information, refer to the MS/TP Communications Bus
Technical Bulletin (LIT-12011034).
Symptom Probable Causes
Multiple Symptoms Excessive bus errors may be occurring.
A device may have been added or changed with a duplicate address
(may not be the same address as some devices having problems, and
may have happened sometime before the problem was noticed).
Wiring errors or wire problems may exist.
The baud rate may have been changed on some devices on the network
but not all devices.
Max_Master may have been changed incorrectly (may have happened
sometime before the problem was noticed).
A download may be in progress.
There may be a fault at a device.
A repeater may be needed or may be configured incorrectly.
There may be a duplicate device object name or instance.
Poor Performance See the probable causes listed previously in the Multiple Symptoms
section of this table.
Excessive bus traffic may exist (bus overload).
The baud rate may be set too low.
There may be too many devices on the network.
There may be unaccounted devices on the network (not mapped to the
NAE).
There may be unusually slow devices on the network or devices that are
slow to respond.
Controller Goes
Offline See the probable causes listed previously in the Multiple Symptoms section of this table.
A power failure or other failure may have occurred at the controller.
Communication may have been disabled at the controller.
Controller Does Not
Come Online See the probable causes listed previously in the Multiple Symptoms section of this table.
A controller may be connected to the wrong bus.
A baud rate may be specified in the new controller that is incompatible
with the running network.
No device on the network is configured to use a specific baud rate
(normally the NAE), but all devices are set to use auto baud. At least one
device, typically the bus supervisor (NAE), must have an assigned baud
rate. Set the baud rate in the bus supervisor and set all other devices to
auto baud.

1. This MS/TP Bus object is readable and only writable if the corresponding override object is set. (For
example, Room Temp has a corresponding override object of Room Temp Override. This
corresponding override object needs to be set to 1 = Override to be able to write Room Temp to a
different value.)
2. This MS/TP Bus object may automatically release after 10 minutes with no BACnet traffic.
3. This MS/TP Bus object is readable and writable.
4. This MS/TP Bus object is valid only if it is written via the network.
5. This MS/TP Bus object is readable only.
6. The BI object type status is available even if the configuration is set to None.
7. If one setpoint of a pair of heating and cooling setpoints (for example, Occupied Heat Setpoint and
Occupied Cool Setpoint) is overridden, the other setpoint of the pair may be automatically adjusted by
the thermostat to maintain the minimum deadband between the two setpoints.
8. Max_Master is writable.
