TEC26x7-4 Series BACnet® MS/TP Networked Thermostat Controllers with Two
Outputs Installation Instructions
Applications
The TEC26x7-4 Series Thermostat Controllers are
BACnet® Master-Slave/Token-Passing (MS/TP)
networked devices that provide control of local
hydronic reheat valves, pressure dependent Variable
Air Volume (VAV) equipment with or without local
reheat, or other zoning equipment using an on/off,
floating, or proportional 0 to 10 VDC control input. The
technologically advanced TEC26x7-4 Series
Thermostat Controllers feature a Building Automation
System (BAS) BACnet MS/TP communication
capability that enables remote monitoring and
programming for efficient space temperature control.
The TEC26x7-4 Series Thermostat Controllers feature
an intuitive user interface with backlit display that
makes setup and operation quick and easy. The
thermostat controllers also employ a unique,
Proportional-Integral (PI) time-proportioning algorithm
that virtually eliminates temperature offset associated
with traditional, differential-based thermostat
controllers.

Location Considerations
Locate the TEC26x7-4 Series Thermostat Controller:
• on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature
• away from direct sunlight, radiant heat, outside
walls, behind doors, air discharge grills, stairwells,
or outside doors
• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
Note: Allow for vertical air circulation to the
TEC26x7-4 Series Thermostat Controller.
IMPORTANT: The TEC26x7-4 Series Thermostat
Controllers are 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.
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when this equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in

TEC26x7-4 Series BACnet® MS/TP Networked Thermostat Controllers with Two Outputs Installation
Instructions
To install the thermostat controller:
1. Use a Phillips-head screwdriver to remove the
security screw if it is installed on the bottom of the
thermostat controller cover.
Note: Normally, the security screw is packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed
on the bottom of the cover.
2. Pull the bottom edge of the thermostat controller
cover and open the thermostat controller as
illustrated in Figure 1.
3. Carefully pull the locking tabs on the right side of
the thermostat controller mounting base and
unlock the Printed Circuit Board (PCB). Open the
PCB to the left as illustrated in Figure 2.
4. Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the hole in the
thermostat controller mounting base.
5. Align the thermostat controller mounting base on
the wall and use the base as a template to mark
the two mounting hole locations.
6. Position the thermostat mounting base so that the
arrow on the base points upward to indicate the top
of the thermostat.
Note: If you need to install the thermostat 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 you have enough space for
cabling and end-of-line devices, if needed.
Note: For surface-mount applications, use
durable mounting hardware such as Molly bolt
anchors that cannot be easily pulled out of the
mounting surface.
7. Secure the base to the wall surface using two
mounting screws as illustrated in Figure 3.
Note: Be careful not to overtighten the mounting
screws.
8. Swing the PCB back to the right and carefully snap
it into the locking tabs on the thermostat controller
mounting base.
9. Remove the screw terminal blocks that are
attached to a disposable adhesive. Figure 4
illustrates the locations of the screw terminal
blocks on the thermostat controller.

TEC26x7-4 Series BACnet® MS/TP Networked Thermostat Controllers with Two Outputs Installation
Instructions
Wiring
When an existing thermostat controller is replaced,
remove and label the wires to identify the terminal
functions. When a TEC26x7-4 Series Thermostat
Controller is replaced, simply remove the old screw
terminal blocks and reinsert them onto the PCB of the
replacement thermostat controller.
To wire the thermostat controller:
1. Strip the ends of each wire 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Table 1 and Figure 5 through
Figure 18.
Note: For more details on wiring the MS/TP
Communications Bus, refer to the MS/TP
Communications Bus Technical Bulletin
(LIT-12011034).
2. Carefully push any excess wire back into the wall.
Note: Seal the hole in the wall with fireproof
material to prevent drafts from affecting the
ambient temperature readings.
3. Reinsert the screw terminal blocks onto the PCB.
4. Reattach the MS/TP communication wires to the
terminal block.
Note: If multiple wires are inserted into the
terminals, be sure to properly twist the wires
together prior to inserting them into the terminal
connectors.
5. Reattach the thermostat controller cover to the
mounting base (top side first).
6. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the thermostat
controller cover.
IMPORTANT: Because some of the objects may
not directly correlate to a previous version, you must
rediscover all point objects for the TEC26x7-4
version. For detailed information on this mapping,
refer to the TEC BACnet® MS/TP Network Series
Thermostat Controllers Technical Bulletin
(LIT-12011592).

TEC26x7-4 Series BACnet® MS/TP Networked Thermostat Controllers with Two Outputs Installation
Instructions
Connecting the MS/TP Bus
To connect the MS/TP Bus:
1. Set the MS/TP address of the TEC BACnet MS/TP
Network Series Thermostat Controller per the
engineering drawings and test for bus voltage,
polarity, and isolation prior to wiring the MS/TP
Bus. Use the Com addr parameter to set the
MS/TP address for the thermostat controller.
Note: The wiring rules for the MS/TP Bus differ
from the wiring rules for the N2 Bus. 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 thermostat controller.
3. After the bus wires are connected to the first
thermostat controller, continue in a daisy-chained
fashion to the next thermostat 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 the
rooftop controller is not equipped with end-of-line
termination, a Johnson Controls MS-BACEOL-0
End-of-Line Terminator (see Table 5; 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.
The thermostat controller has 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 thermostat controller
cover (on the left edge when facing the thermostat
controller) indicates the communications mode when
the thermostat 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 thermostat
controller is scanning for the correct baud rate and
that there is no communication.
•Off: Indicates that there is no power to the
thermostat 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 Thermostat Controller Mapping
For detailed information on MS/TP Bus objects and
thermostat controller mapping, refer to the TEC
BACnet MS/TP Network Series Thermostat Controllers
Technical Bulletin (LIT-12011592).

The TEC26x7-4 Series Thermostat Controller user
interface consists of three keys on the front cover
(Figure 19). The function of each key is as follows:
•OVERRIDE key overrides the unoccupied mode to
occupied at the local user interface for the
specified TOccTime. (TOccTime is defined by
selecting the appropriate time period in the Installer
Configuration Menu.) If one of the binary inputs is
configured to operate as a remote override contact,
this OVERRIDE function is disabled. The

BI2 Configuration of Binary Input 2.
Default: None
(None): No function is associated with an input.
(Door Dry): Door contact only has an effect if BI1 is set to MotionNO
or MotionNC. (See the BI1 parameter in this table.) The occupancy
is now dictated via BI1 and BI2. Any motion detected sets the zone
to Occupied status. The zone remains permanently in occupied
mode until the door contact switch opens momentarily. The
thermostat controller then enters stand-by mode. If more
movements are detected, the occupied mode resumes. While the
door is opened, any movements detected by the remote PIR sensor
or the PIR accessory cover are ignored. Use a Normally Closed
contact switching device. Contact opened = Door opened,
Contact closed = Door closed.
(RemOVR): Temporary occupancy request via a remote input. This
override function is controlled by a manual remote occupancy
override. When enabled, this condition disables the override
capability of the thermostat controller.
(Filter): A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.
(Service): A Service alarm is displayed on the thermostat controller
when the input is energized. This input can be tied into the air
conditioning unit control card, which provides an alarm should there
be a malfunction.
UI3 Configuration of Universal Input 3.
Default: None
(None): No function is associated with an input.
(COC/NH): Changeover Contact/Normally Heat: A dry contact input
is used to signal seasonal hot/cold water changeover. The contact

St-By TM Sets the Stand-By timer value
(PIR models).
Default: 0.5 hours
Time delay between the moment the PIR cover detected the last
movement in the area and the time at which the thermostat
controller Stand-By mode and setpoints become active.
Range: 0.5 to 24.0 hrs adjustable in 0.5-hour increments
Unocc TM Sets the Unoccupied timer value
(PIR models).
Default: 0.0 hours
Time delay between the moment the thermostat controller toggled to
Stand-By mode and the time at which the thermostat controller
Unoccupied mode and setpoints become active. Setting this
parameter to the factory value (0.0 hours) disables the Unoccupied
timer. This prevents the thermostat controller from switching from
Stand-By mode to Unoccupied mode when PIR functions are used.
