Installation Tips
Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the
floor. Select an area with average temperature and good air circulation.
Do not install thermostat in these locations:
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes
Installation Tip
Pick an installation location that is easy for the user to access. The temperature
of the location should be representative of the building.
