8 BAS-SVX44A-EN

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

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.

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.

20 BAS-SVX44A-EN

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.
