INSTALLATION TIPS
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 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
• Where appliances could radiate heat
Pick an installation location that is easy for the user to access. The temperature of the location
should be representative of the building.

PRO1 Tip
When performing an attic installation, instead of placing the base module in the attic, locate
the closet nearest to the air conditioning unit. Then mount the base module high on the wall
inside the closet or on the ceiling of the closet. This location will insure the base module is
below the 150ºF maximum ambient temperature specification.
