Getting to know your indoor remote sensor or zone control
Recommended Wall Mounting Locations
The remote sensor should be mounted or placed approximately 4 to 5 feet above the
oor. Select an area with average temperature and good air circulation.
Do not mount or place Remote Sensors 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 appliances could radiate heat
• Do not set it next to or on hot appliances
• Do not put it in your pocket or hold in your hands for a long period of time.
• Body heat will distort the temperature reading.
