SAFETY WARNING

BAS-SVN028K-EN

Introduction

Read this manual thoroughly before operating or servicing
this unit.

Warnings, Cautions, and Notices

Safety advisories appear throughout this manual as
required. Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.

The three types of advisories are defined as follows:

WARNING

CAUTIONs

NOTICE

Important Environmental Concerns

Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment. Trane advocates the responsible handli ng of
all refrigerants-including industry replacements for CFCs
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.

Important Responsible Refrigerant
Practices

Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified according to local rules. For
the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and
recycling of certain refrigerants and the equipment that is
used in these service procedures. In addition, some states
or municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.

Indicates a potentially hazardous
situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.

Indicates a situation that could result in
equipment or property-damage only
accidents.

WARNING

Proper Field Wiring and Grounding
Required!

Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.

WARNING

Personal Protective Equipment (PPE)
Required!

Failure to wear proper PPE for the job being undertaken
could result in death or serious injury. Technicians, in
order to protect themselves from potential electrical,
mechanical, and chemical hazards, MUST follow
precautions in this manual and on the tags, stickers,
and labels, as well as the instructions below:

• Before installing/servicing this unit, technicians

Installation

Location Guidelines

• Do not install on an outside wall.

• Do not install in areas with direct heat source.

• Do not install near any air discharge grill.

• Do not install in areas exposed to direct sunlight.

• Ensure the sensor has sufficient air circulation.

• Ensure the mounting wall surface is flat and clean.

Installing the Sensor

1. Remove the security screw from the bottom of the
sensor (if present).

2. Firmly grasp the sensor and pull up on the bottom to
remove the front cover.

3. Feed the wires from the wall through the backside of
sensor base.

4. Ensure the sensor is oriented correctly. The word 'TOP'
is embossed on the backplate to indicate correct
orientation. Mark the top/bottom mounting hole
locations on the wall.

5. Install the provided wall anchors and then affix the
sensor base to the wall using the provided screws.

6. Strip the wire coating from the ends of each wire
approximately 0.25 inch.

7. Insert the wires into the wire terminals (per terminal
identification below) and tighten down the terminal
screws to secure wire.

8. Push any excess wire back into the wall and then
replace the sensor cover. Once the cover snaps on, the
sensor powers up.

9. Replace the security screw on the bottom of the sensor
to avoid tampering.

6 BAS-SVN028K-EN

Zone Sensor Wiring

Wiring the zone sensor to the HVAC equipment varies
based on the control system to which the sensor is
connected. Reference one of the following electrical
schematics for proper wiring installation of the zone
sensor to the HVAC equipment.

Communication Wire

Use the correct communication wire to ensure reliable
communication between the zone sensor and the HVAC
equipment. Trane recommends the following wire
supplier and wire type.

Important: This sensor can only be used with

standalone HVAC equipment. It cannot be
used on a BACnet/MSTP link connected to a
BAS.

Suggested Supplier: Windy City Wire

• Plenum rated P/N: 043005AL

• Non-plenum rated P/N: 108760

Other wire may be used if it conforms to the following
physical characteristics:

• Twisted pair (2-conductor) plus shield.

• Characteristic Impedance: 100 and 130 ohms.

• Distributed capacitance between conductors: < 100 pF/
m.

• Distributed capacitance between conductor and
shield: < 200 pF/m.

• Foil or braided shield is acceptable.

• Wire diameter: 22 to 18 AWG.

Important: Configure the Temp Sensor parameter as

needed. See 2/4 Configuration menu for
details.

External Sensor Inputs

The zone sensor supports three external inputs that can be
used to control the behavior of the sensor.

• Demand shed signal. A dry contact relay can be wired
to terminals 16 and 18. Closure of the contact indicates
to the sensor that a demand shed request is present.

• Motion Sensor or external occupancy signal. A dry
contact relay can be wired to terminals 17 and 18.
Closure of the contact indicates to the sensor that the
space is not occupied.

When the sensor is configured for occupied standby
control and it is in occupied mode based on a time
schedule. Closure of the contact indicates the space is
not occupied and the sensor enters occupied standby
mode.

• Space temperature signal. Use a 10k ohm, type 2
thermistor/sensor when using a remote mounted
space sensor wired to terminals 17 and 18, or wired to
HVAC equipment.

BAS-SVN028K-EN 7

Zone Sensor Wiring

ReliaTel Systems

The zone sensor and the BCI-R form a two-node BACnet
MS/TP network. Wire the system as shown in the
schematic below while adhering to the following
recommendations:

• At the RTRM board, terminate the shield wire at J7­COM terminal. The shield wire may need to be
extended to make this connection. Use an insulated

extension wire to prevent contact with the metal
enclosure and circuit boards.

• Set the link switch on the BCI-R to BACnet.

Important: Install a jumper wire between terminals J6-

1 and 2 when the internal temperature
sensor or a sensor wired to terminals 17 and

.

18 is used.

ReliaTel Field Upgrade Procedure

When ReliaTel controlled equipment is modified in the
field in a manner that changes the point configuration of
the unit, the BCI-R must interrogate the ReliaTel control
system to learn the new points list of the equipment. This
action only takes place during initial power-up after the
BCI-R device memory has been cleared. The new point list
is permanently stored in the memory of the BCI-R device.

BCI-R Initialization Procedure

Use the BACnet Setup Tool to clear the controller and
restore to factory defaults.

1. Navigate to the Controller Settings screen.

2. Click within the light gray area of the bottom left of the
screen just above the “Connected” indicator.

The Clear Controller button appears at the top right of
the screen.

3. Click Clear Controller.

A message appears stating that the configuration will
be reset (deleted).

4. Click OK.

When the controller is cleared, the Select Device Units
message box appears.

5. Click OK and then expand the Controller Units box on
the Controller Settings screen.

6. Select the units (SI, IP, or Custom).

Note: This selection defaults to Custom after clearing

the controller. If you want to use Custom,
ensure that all unit options are set correctly.

7. Click Save.
