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.govand 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.

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 Table2.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. 8and
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
Figure1, p.11).
