Pre-Installation
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 when installing the thermostat:
Direct sunlight
Direct airstream of air diffusers
Exterior walls and other walls that have a temperature differential between the two sides
Close proximity to heat sources such as sunlight, appliances, concealed pipes, chimneys, or
other heat-generating equipment
Drafty regions
Dead spots behind doors, projection screens, or corners
Walls subject to high vibration
High humidity regions
High traffic areas (to reduce accidental damage or tampering)
Height Requirements
It is recommended to mount the thermostat a maximum distance of 54 inches (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: For further details regarding wheelchair requirements, refer to ADA Standards for
Accessible Design/4.27 Controls and Operating Mechanisms/4.27.3 Height online at
www.ADA.gov and to local building codes.
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. For other surface types, the
user must provide fasteners that are appropriate for the surface.
BAS-SVX44A-EN 9
Pre-Installation
Maximum Wire Length
The thermostat may not function properly if the total resistance of any of the thermostat wires
exceeds 2.5 ohms (refer to Table 2).
Important: Ensure
that the wires from the thermostat to the HVAC equipment do not exceed
lengths shown in Table 2. Best
practice: use shorter wire lengths.

Installation and Wiring
This section provides information about the following:
Mounting the thermostat and cover removal
Wiring and wiring diagrams
Thermostat cover replacement
Mounting the Thermostat and Cover Removal
Before beginning installation, it is recommended to re-read the section, “Pre-Installation,” p. 8 and
then ensure that 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 color coded
Mounting the Backplate
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 can permanently damage it.
To mount the backplate:
1. Shut off the power to all HVAC equipment. If the security screw was previously installed,
remove it (refer to
Figure 1, p. 11).
BAS-SVX44A-EN 11
Installation and Wiring
Figure 1. Security screw removal and cover release
2. Push the cover thumb tab to release the cover from the backplate as shown above.
3. Route the wires through the opening in the backplate as shown below. Wires should be marked
to
ensure proper connection to terminals.
Figure 2. Wire routing, mounting, and mounting dimensions
4. If mounting the backplate directly to a wall surface, hold the backplate against the surface and
then
level and mark the fastener locations.
5. Secure the backplate using appropriate fasteners (refer to the section, “Mounting Surfaces,”
p. 8.) The thermostat must be level and plumb to ensure proper air movement through the
thermostat enclosure.

security screw is
installed, remove

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 can permanently damage it.
Note: Terminal
blocks are included with the mounting hardware contained in a small plastic bag
(new installation) or remove terminal blocks from pin header (existing installation).
To wire the thermostat:
1. Connect the wires to the terminal block(s) by:
a. Removing approximately 1/4 inch (6 mm) of insulation from the wires.
b. Using the terminal block screws to securely fasten each wire into the terminal block.
Note: Refer
to Table 3, p. 13 and the wiring diagrams on page 14- through 18 to
determine the correct terminal for each wire.
In some cases the terminal labels (such as Y, G, or R) correctly correspond to the
first
letter of the color wire in which they are connected. However, it is important to
verify which equipment terminals are connected at the other ends of the wires
before connecting the wires to the thermostat.
2. Align the pins/label on the circuit board with the holes/label on the terminal blocks and gently
push
the wired terminal blocks into place on the circuit board (refer to Figure 3).
Figure 3. Attaching the wired terminal blocks to the pins on the circuit boards
3. Push the excess wire through the hole in the wall cavity or into the junction box.
Important: Do not coil excess wire between the thermostat and the backplate. Use non-
flammable insulation to prevent air movement between the wall cavity and the
thermostat.

Power, System Tests, and Software Reset
This section provides information about:
Applying power
Power-up test
System tests
Applying Power
Restore power to the HVAC equipment. The thermostat initiates a power-up test and will display
an error, if one is detected (refer to the sections, “Power-up Test,” p. 19 and “Error Codes,” p. 48).
If no errors are detected, the home screen appears as shown in Figure 16.
Figure 16. Home screens
Power-up Test
The power-up test is performed any time power is applied to the thermostat. At the start of the
power-up test, the thermostat screen will display the following sequence of events, in order:
All icons for approximately 1.5 seconds and then;
The firmware version for 1.5 seconds (in
the clock digit location), and finally;
Self-testing.
If an error is detected, the error code will display whereby, the user can bypass the error by pressing
the Cancel icon
( ). Once the self-testing has completed checking for any errors, the thermostat
will display the Home screen.
During the test, the configuration/test icon ( ) blinks on the LCD screen indicating a test is in
progress. Table 5 lists the sequence of tests that occurs:
Note: For a detailed list and descriptions of error codes, refer to the section, “Error Codes,” p. 48.

Power, System Tests, and Software Reset
System Tests
The system test mode is used to run diagnostics on the thermostat to verify that the unit is
functioning properly.
Referring to Table 6, p. 22, to run a system test:
1. Remove the thermostat cover as shown in the section,“Mounting the Backplate,” p. 10.
2. Press and hold the Configuration button
(refer to Figure 17, p. 21) for 3 seconds. The
configuration/test icon ( ) displays and the thermostat is now in Configuration
Setup
Mode.
3. Press and hold the Configuration button
for 3 seconds again to activate System Test Mode
indicated by the blinking parameter/test icon. When activating system test mode, the first
system test number displayed is always 01.
The test number is changed with the Up ( ) or Down ( ) arrows in the center of the display
screen.
Note: The OK button ( ) functions the same as the Up arrow and steps to the next
higher test number.
The test value is changed with the Up ( ) or Down ( ) arrows on the right-hand side of
the display screen.
Note: Changing
a test value will start/stop the test as described in Table 6. Refer to
Figure 17 for arrow locations and Table 6, p. 22 for a list of test values and test
value descriptions.
4. Exit the System
Test Mode and return to the Home screen by:
a. Pressing the Configuration button
momentarily (less than 3 seconds).
b. Touching and holding for 2 seconds.
c. Powering down the thermostat and then powering it up again.
d. Waiting for a 10-minute time out after the last touch.
