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.
18 AWG (0.75 mm2) 385 ft (117 m) 2,500 ft (762 m) 385 ft (117 m)
20 AWG (0.50 mm2) 240 ft (73 m) 1,500 ft (457 m) 240 ft (73 m)
22 AWG (0.33 mm2) 150 ft (46 m) 1,000 ft (305 m) 150 ft (46 m)

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).
