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.

Wireless Type Selection
The thermostat and base module contain selectable wireless
communication options. Each component has a jumper switch label
FSK and ASK. Default setting: FSK.
• All components must be set to the same position for wireless
communication.
• Both modes utilize a 916 MHz frequency.
• FSK: frequency-shift keying, is the recommended mode.
• ASK: amplitude-shift keying, should be selected when using
components that can not communicate with FSK.
The images below illustrate the location of jumper switches for each
item that has one. Note only the thermostat and Base Module are
