The thermostat can operate the fan in 3 ways:
• AUTO (on only during heating and cooling calls)
• ON (always on)
• PROGRAMMED FAN (fan follows the program set in the program screen)
The FAN MENU, located in the MAIN MENU, has these three options for you to choose from.
NOTE: When installed with an Aprilaire

Model 6504 you will be given the option to CHANGE ALL
THERMOSTATS. If you select YES to this, the fan setting will be set to whatever you have selected for
all the thermostats on the system.
