Pre-Installation
This section provides the following pre-installation information:
•
Location considerations
•
Height requirements
•
Mounting surfaces
•
Maximum wire length
Location Considerations
When selecting a location, avoid the following:
•
Areas of direct sunlight
•
Areas in the direct airstream of air diffusers
•
Exterior walls and other walls that have a temperature differential between the two sides
•
Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys,
or other heat-generating equipment
•
Drafty areas
•
Dead spots behind doors, projection screens, or corners
•
Walls that are subject to high vibration
•
Areas with high humidity
•
High traffic areas (to reduce accidental damage or tampering)
Height Requirements
It is recommended that you mount the back plate a maximum distance of 54 in. (137 cm) above the
floor. If a parallel approach by a person in a wheelchair is required, reduce the maximum height
to 48 inches.
Note: Consult section 4.27.3 of the 2002 Americans with Disability Act guideline, and local building
codes, for further details regarding wheelchair requirements.
Mounting Surfaces
The thermostat can be mounted to any sturdy, vertical surface. Plastic threaded anchors and
M3.5 x 20 mm screws are provided for mounting to plaster or wallboard; 6-32 x 3/4 inch machine
screws are provided for mounting directly to a standard electrical device box. Other fastener
varieties may be required for other surface types.
When replacing a horizontally mounted thermostat and there is an adapter kit available to cover
any opening in the wall. Contact your localTrane office for more information.

Pre-Installation
Maximum Wire Lengths
Thermostat to HVAC Equipment
The thermostat may not function properly if the total resistance of any of the thermostat to HVAC
equipment wires exceeds 2.5 ohms.To ensure that wire length does not cause excess resistance,
refer to Table 1 and ensure that the wires from the thermostat to the HVAC equipment are not too
long.
Table 1.
Maximum Thermostat to HVAC Equipment Wire Lengths
Copper wire size
Maximum recommended wire length
22 AWG (0.33
mm2)
150 ft (46 m)
20 AWG (0.50
mm2)
240 ft (73 m)
18 AWG (0.75
mm2)
385 ft (117 m)
Remote Sensor to Programmable Thermostat
Because remote temperature sensors measure resistance, very long cable runs can cause slight
errors in the measurement. For the highest temperature reading accuracy, avoid exceeding the
maximum recommended wire lengths shown in Table 2.
Table 2.
Maximum Recommended Remote Sensor Wire Length
Copper wire size
Maximum recommended remote
sensor wire length
22 AWG (0.33 mm2)
1000 ft (300 m)
20 AWG (0.50 mm2)
1500 ft (450 m)
18 AWG (0.75 mm2)
2500 ft (750 m)
Note: For 22 AWG (0.33 mm2) copper wires, the rate of error can be up to 0.5 °F (0.3 °C) per 100 ,
which typically requires wire lengths in excess of 5000 ft (1500 m).

BAS-SVX36C-EN
Installation
This section provides installation instructions.
Before you begin, read through the pre-installation information, beginning on p. 9, and also verify
the following conditions are met:
•
A wire access hole is available at the thermostat location.
•
The wires are accessible through the hole.
•
The wires are attached to the appropriate terminals on the HVAC equipment.
•
There is continuity (and not more than 2.5 ohms resistance) between the thermostat location
and the HVAC equipment.
•
The wires are accurately labeled or identified by color.
Mounting the Back Plate
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the thermostat will permanently damage it.
To mount the back plate:
1. Shut off power to the HVAC equipment.
Note: If the security screw is installed, remove it before attempting to remove the cover.
See Figure 3.
Figure 3.
Security Screw Location (if used)

Installation
Figure 4. Feeding Wires through Back Plate
4. If you are mounting the back plate directly to a wall surface, hold the back plate against the
surface and mark the fastener locations.
5. Secure the back plate using appropriate fasteners. (See “Mounting Surfaces,” p. 9.)The
thermostat must be level and plumb for accurate temperature control and to ensure proper air
movement through the thermostat enclosure.
Wiring
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the thermostat will permanently damage it.
General Practice
To wire the thermostat:
1. Connect the wires to the terminal block(s) packaged in the box with the thermostat. (The
programmable thermostat has two terminal blocks, the non-programmable thermostats have
only one):
• Remove approximately 1/4 inch (6 mm) of insulation from the wires.
• Use the terminal block screws to securely fasten each wire into the terminal block.
• Refer to the section, “Terminal Identification,” p. 13 and the wiring diagrams on the pages
that follow to determine the correct terminal for each wire.
Note: In some cases the terminal labels (Y, G, R, etc.) correctly correspond to first letter of the
color wire to which they are connected. However, you must verify which equipment
terminals are connected at the other ends of the wires before connecting the wires to
the thermostat.

Installation
2. Align the pins on the circuit board with the holes on the bottom of the terminal blocks and gently
push the wired terminal blocks into place on the circuit board. See Figure 5.

Overview of Operation
If configured properly, both programmable and non-programmable thermostats will control HVAC
equipment to maintain room temperature automatically.
BAS-SVX36C-EN
33
Operation
Non-Programmable Thermostats
Non-programmable thermostats do not have timekeeping or scheduling capabilities.They will
continue to maintain heating and/or cooling setpoints until an operator makes changes to the
setup.Therefore, only the following tasks may be required performed:
•
Change the system mode.
•
Show or change the heating or cooling temperature setpoint.
•
Change the fan mode.
Note: The system mode, temperature setpoints, and fan mode can each be individually locked to
prevent users from changing them. If you see a
on the display, you may need to unlock
the setting before you change it (see “Locking or Unlocking Modes,” p. 40).
Changing the System Mode
Note: If you are unable to change the system mode, check the system type setting and the manual/
auto changeover setting (see “Configuration,” p. 26) to verify that the thermostat is
configured with heat and cool modes, and that it permits manually changing them.
Depending upon the model and system type, the thermostat can be set to one of five modes:
Cooling, Heating, Emergency Heat, Auto, or Off.
Cooling mode cools the room to bring it down to the cooling setpoint.
Heating mode heats the room to bring it up to the heating setpoint.
Emergency Heat mode heats the room according to the heating unit’s emergency heat mode
settings.
Auto mode switches automatically between heating and cooling modes as required.
Off mode prevents the thermostat from requesting any heating or cooling regardless of the
room temperature. Off mode also disables fan selection and prevents the user from changing
the setpoint.
Note: The 1-Heat/1-Cool thermostat does not have Emergency Heat mode.

Programmable Thermostats
Programmable thermostats contain all of the functionality of the non-programmable thermostats,
but they also keep track of the date, day of week, and time of day for scheduling purposes.
Programming
This section describes how to program the thermostat after it has been installed and configured.

Operation
Scheduling
The thermostat can be configured for two periods (day and night) or four periods (morning, day,
evening, and night).The chosen number of periods are applied to each day of the week when you
program the thermostat. Each period can have a unique start time, heat setpoint, cool setpoint, and
fan setting.
The groups of days can be one of the following:
•
1 day = all 7 days of the week follow the same schedule.
•
5+1+1 days = Monday - Friday all follow the same schedule; Saturday and Sunday each follow
their own schedules.
•
5+2 days = Monday - Friday all follow the same schedule; Saturday and Sunday follow the same
schedule, which is different than the Monday - Friday schedule.
•
7 days = Each day follows its own schedule.
Note: See “Configuration,” p. 26 to change the number of periods in a day or the grouping of days
in the schedule.
If needed, you can use Table 9 to write down your schedule settings before you begin setting up
the schedule.The default schedule is also shown in the table. Unless you program your own
schedule settings, the thermostat follows the default schedule for all days of the week.

Operation
Day-to-Day Operation
After a programmable thermostat is configured and the schedule is programmed, the thermostat
automatically changes the setpoints and fan settings according to the schedule.However, there are
some operator tasks that you may need or want to perform:
•
Show setpoint or current temperature.You can temporarily or permanently switch the main
display from current temperature to temperature setpoint. See “Showing the Setpoint or
Temperature on Display,” p. 39.
•
Set the system mode, which includes turning the system on or off, and switching between
heating, cooling, and automatic heating and cooling. See “Changing the System Mode,” p. 34.
•
Override the schedule. If an unexpected, one-time temperature setpoint or fan mode change is
needed you can temporarily override the schedule. See “Timed Override (TOV) Mode,” p. 40.
•
Lock or unlock.You can lock the thermostat buttons to prevent changes to the thermostat
settings. See “Locking or Unlocking Modes,” p. 40.
Note: It is possible for a programmable thermostat to be configured to be a non-programmable
thermostat. If installation configuration option #140 is set to 0, schedule programming
capabilities will be absent.

Operational and Programming Reference Information
This section provides additional information that may be useful for understanding thermostat
operation or programming.
Deadband
The thermostat automatically maintains a temperature deadband between the heating setpoint
and the cooling setpoint whenever automatic changeover (heat-to-cool or cool-to-heat mode) is
enabled.The temperature range of the deadband is 2–9 °F (1.0–4.5°C) and is specified in the
installation configuration options (see “Configuration,” p. 26). If you attempt to change a
temperature setpoint to within the deadband of its opposing setpoint, the opposing setpoint will
automatically be pushed to the next value that satisfies the deadband. (See Figure 38.)
Heat and Cool Cycling Rate
The heat and cool cycling rate, expressed in cycles per hour (CPH) indicates how often heating or
cooling system is turned on when temperature is within the temperature differential from the
setpoint, which is 1°F (0.5°C).There are ten options (1–10) for heat stages and five options (1–5) for
cool stages.The number selected is the maximum number of times the stage is cycled in 1 hr.
For example, when the system is set to 5 CPH, it runs at 12 min cycles with variable duty cycle.
Depending on the heating or cooling load, which is measured by feedback from the sensor
thermistor and/or temperature error, the system could run at 50% duty cycle (6 min ON and 6 min
OFF), 80% duty cycle (9.6 min ON and 2.4 min OFF), or other variations of the duty cycle.
Note: The cycling rate described above is only active when the temperature is within the
temperature differential. If the temperature is outside of the temperature, the heating and
cooling equipment will either be fully on or fully off accordingly. (See Figure 38.)

There is one cycling rate setting for each of the thermostat’s available heat and cool stages,
including auxiliary and emergency heat stages.You can specify them during installation
configuration. See “Configuration,” p. 26.
Minimum Compressor Off Time
To protect the compressor from cycling too frequently, there is an automatic 5 min gap between
cycles.You cannot reduce the gap, but you can add up to 5 min if needed. See “Configuration,”
p. 26.
BAS-SVX36C-EN

Operational and Programming Reference Information
Configuration and Programming Retention
The thermostat retains the time and date for a minimum of 5 days with no electricity. If power is
lost for more than 5 days, you will need to reset the time and date when power is restored.
All configuration parameters, system settings, and scheduling are stored in non-volatile memory,
which will retain the data indefinitely with or without power.
Note: You can manually revert to default settings by setting the appropriate installation parameter
(#300 for programmable thermostats or #18 for non-programmable thermostats) to a value
of 1, and exiting configuration mode.
Extended Fan-on Time (Heat or Cool)
Note: This feature applies only to the programmable thermostat.
When the thermostat fan is in Auto mode, the fan on time can be extended.
•
Configuration option #270 extends the fan on time by 90 sec after heat turns off.
•
Configuration option #271extends the fan on time by 40 sec after cool turns off.
These options may not be available for some system configurations. See “Configuration,” p. 26.
Compressor and Auxiliary Heat Lockout
Note: This feature applies only to the programmable thermostat.
Compressor and auxiliary heat is used for heat pump systems with more heat stages than cool
stages. When the temperature from an outdoor sensor is
•
above the auxiliary lockout point, only the compressor will operate on a call for heat.
•
below the compressor lockout point, only the auxiliary heat will operate on a call for heat.
•
between the compressor and auxiliary lockout point, the compressor and auxiliary heat will
operate on a call for heat.
There is a minimum 5°F (2.5°C) deadband between compressor and auxiliary heat lockout
temperatures. Configuration option #220 sets the compressor lockout point; #221 sets the auxiliary
lockout point. See “Configuration,” p. 26.
Auxiliary Heat Control
Note: This feature applies only to the non-programmable 3-Heat/2-Cool thermostat.
You can set the auxiliary heat control using configuration option #17 to one of two settings:
•
Comfort - prioritizes comfort over economy. Raising the temperature just a few degrees often
will activate the auxiliary heat.
•
Economy - attempts to reach the temperature setting without activating the auxiliary heat.
Economizer/TOD
Note: This feature applies only to the programmable thermostat.
You can set the Economizer orTOD mode using configuration option #150 to one of two settings:

• Check the power supply.
• If the power supply is ok, have the thermostat serviced or replaced by a qualified Trane
supplier.
Erratic display
appearance or contrast
• Check the power supply.
• Check the frequency configuration (Configuration option #210 for the programmable
thermostat or #11 for non-programmable thermostats) to make sure that you are using
the correct frequency setting for your power supply.
• If the power supply and frequency setting are ok, have the thermostat serviced or
replaced by a qualified Trane supplier.
Buttons do not respond
• Make sure the thermostat modes are not locked. See “Locking or Unlocking Modes,”
p. 40.
• Cycle the power to the thermostat.
• If the modes are not locked and cycling the power do not solve the problem, have the
thermostat serviced or replaced by a qualified Trane supplier.
“--F” or “--C” flashes
• Temperature is outside of the measurable range. The temperature reading should be
correct when the temperature is within the measurable range.
Fan settings are not
visible
• Check the system status. If the status is Off, the fan settings will not appear.
• Check the configuration options to verify that the fan is enabled:
For programmable thermostats, check options 0130 and 0151;
