and an intuitive user interface for easy operation. With built-in remote access capability, users can easily
perform tasks via a mobile device (iOS or Android).
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
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
CAUTION
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.
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/national 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, ALWAYS refer to the appropriate SDS
and OSHA/GHS (Global Harmonized System of Classification and Labelling 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 SWITCHING,
DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND
ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE
PROPERLY RATED FOR INTENDED VOLTAGE.

WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS)
policies when performing work such as hot work, electrical, fall protection, lockout/
tagout, refrigerant handling, etc. Where local regulations are more stringent than these
policies, those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

Binary Input Open state
In order for the Binary Input
to recognize an open signal,
the external device, such as
mechanical relay contacts
(recommended gold-plated
contacts), switch, solid state
relay, or opto-isolator outputs
must provide an open signal
that measures greater than
330K ohms —preferably
near infinite ohms. Binary
Inputs are polarity sensitive,
which may affect solid state
relay and opto-isolator output
operation.
Binary Input Closed state
In order for the Binary Input
to recognize a closed signal,
the external device, such as
mechanical relay contacts
(recommended gold-plated
contacts), switch, solid state
relay, or opto-isolator outputs
must provide a closed signal
that measures less than 3.0K
ohms — preferably near 0
ohms. Binary Inputs are
polarity sensitive, which may
affect solid state relay and
opto-isolator output
operation.

Installation and Wiring
Location
The Pivot thermostat is designed for installation in climate controlled spaces. Use the following
guidelines during installation:
• Place the unit in a central location with good air circulation.
• For proper temperature sensing, avoid exposing the unit to heat radiating from lamps, sunlight,
fireplaces, or any other radiant heat sources.
• Avoid locations close to windows, behind doors or alcoves with poor circulation, adjoining outside
walls, or doors leading to the outside.
• Select a location that prevents the unit from direct exposure to air currents from supply registers,
ceiling diffusers, or ceiling fans.
• Mount the unit on a section of interior wall that does not contain hot/cold water pipes or duct work.
Note: The Pivot thermostat utilizes a 4.3 inch color touch screen which generates heat that is vented out
of the top of the unit. If an air source is directed at or from above, heat from the screen can
become trapped within the unit causing inaccurate indoor temperature readings. Refer to the
illustration below.
Heat dissipation
from Touch Screen
Supply register, ceiling
diuser, or ceiling fan
Correct Location
Incorrect Location
Heat from screen may
be trapped within the
body of the unit by an
external top-down
airow source such
as a ceiling diuser
or ceiling fan.
The heat generated by
the onboard electronic
circuitry may cause inaccurate
indoor temperature readings if
heat is not allowed to escape due to
top-down airow.

Network Connections
Connect the Pivot thermostat to the Internet (wireless or wired) for full advantage of the unit features.
• Wireless (Wi-Fi IEEE 802.11 b/g/n, 2.4 GHz only)

BAS-SVX078E-EN 9
– Choose a mounting location that ensures adequate signal strength from the unit to the Internet
router.
– Do not mount the unit more than 30 feet from the wireless router.
– For strong signal strength, ensure there are no more than three (3) interior walls between the
unit and the router.
– Do not mount the unit in areas where electromagnetic emissions from other devices, appliances,
or where wiring can interfere with communication to the unit.
– Do not mount the unit in recessed areas, near metal objects, or near structures.
– Do not have metal obstructions, concrete or brick walls between the unit and the router.
Do not mount the unit closer than 2 inches to any pipes, duct work, or other metal obstructions.
• Wired (Ethernet IEEE 802.3)
– The Pivot thermostat can be connected to the Internet using the built-in RJ-45 connector. When
using a wired connection, verify that a CAT 5, or better, Ethernet cable with an RJ-45 plug is
present from the unit to the router.
Mounting
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when exposed to live electrical components
could result in death or serious injury.
When it is necessary to work with live electrical components, have a qualified licensed
electrician or other individual who has been properly trained in handling live electrical
components perform these tasks.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious injury.
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Verify that
no power is present with a voltmeter.
Note: If replacing an existing unit, remove the unit from the wall, record the color/terminal markings of
each wire, and disconnect the wires from old unit. Do not let the wires fall back through the wall.
1. Turn off all power to cooling/heating equipment.
2. Remove the Pivot thermostat from the box and carefully pry the sub-base away from the unit with a
flat-blade screwdriver.
3. Route the wires through the opening of the sub-base.
4. If using a wired Internet connection, route the Ethernet cable through the opening.
5. Place the sub-base against the wall in the desired location and mark the mounting holes as shown
below.

6. Drill the holes.
Note: An optional mounting hole is provided for more secure mounting.
Note: If using a wireless Internet connection, proceed to Step 8.
7. When using a wired Ethernet connection:
a. With the sub-base and RJ-45 properly oriented, press the holder into the sub-base as shown
below.
b. Slide the holder to the right to snap it into place.
c. Secure the holder with provided screw.
d. Insert the RJ-45 connector into the RJ-45 holder until is snaps into place.
8. Mount the sub-base to the wall using the provided screws and drywall anchors.
