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.
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 handling 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.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates 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.
NOTICE 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
MUST put on all PPE required for the work being
undertaken (Examples; cut resistant gloves/sleeves,
butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Safety Data Sheets
(SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals,
ALWAYSrefer totheappropriateSDSandOSHA/GHS
(Global Harmonized System of Classification and
Labeling of Chemicals) guidelines for information on
allowable personal exposure levels, proper
respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or
flash, technicians MUST put on all PPE in accordance
with OSHA, NFPA 70E, or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit. NEVER PERFORM ANY

BAS-SVN028K-EN 7
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.
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.
Important: Configure the Temp Sensor parameter as
needed. See 2/4 Configuration menu for
details.

Zone Sensor Wiring
8BAS-SVN028K-EN
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 J7-
COM 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
