Changing the Filter Settings
If you set the thermostat to tell you when your filter needs to be changed, you must also indicate how often you want the
thermostat to remind you. You can choose from 30, 60, 90, 120, 150, or 180 days. When the Filter Change Reminder
feature is enabled (see the Disabling the Filter Change Reminder section on page 34 for more information), the
thermostat monitors the number of calendar days since the feature was set. When the operation time reaches the selected
number of days, a filter change reminder icon displays to alert you to change the filter. Perform the following steps to
change the filter settings:
1. On the Main screen, press Mode/Select until the Thermostat Mode screen appears (FIG. 25).
2. Use the navigation buttons to select Settings, and press Mode/Select. The Settings screen appears (FIG. 29).
3. Use the navigation buttons to select Filter.
4. Press Mode/Select to toggle the Filter setting between 30, 60, 90, 120, 150, or 180 days.
If you are unable to change the fan settings, make sure the fan lock is not turned on.
See the Locking the Fan Settings section on page 38 for more information.
