Installation location recommendations
Thermostat should be mounted:
• On an interior wall, in a frequently occupied space.
• Approximately 5' (about 1.5 meters) above the floor.
• At least 18" (about 0.5 meter) from an outside wall.
• Thermostat can be mounted to a vertical, single gang, electrical junction box.
Do not mount thermostat:
• Behind doors, in corners, or other dead air spaces.
• In direct sunlight, near lighting fixtures, or other appliances that give o heat.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near outside doors.
• On a wall with concealed pipes or ductwork.
If replacing an existing thermostat
• If your existing thermostat is configured using system settings, record the
existing system settings so they can be referenced when setting the HVAC
Installer system settings for this thermostat. For detailed instructions on how
to access and read the system settings for your existing thermostat, refer to
the installation instructions for that thermostat.
• Turn o power to the thermostat.
• Remove the thermostat from the wall, but do not disconnect the wires yet.
• Check the number of wires attached to the existing thermostat. Wrap the bare
ends of any unused wires in electrical tape to prevent them from shorting to
other wires.
• If the existing thermostat has a letter identifying each wire, use a piece of tape
to label each wire with the corresponding letter. The labels can be used to
later identify the wires for your new thermostat.
• Disconnect the wires from the existing thermostat, taking care that none of
the wires fall back into the wall.
