If a filter reminder time was setup through the MRX Advanced
Network System Controller when your thermostat was initially

main screen of the thermostat.
To clear the Check: Filter message from the thermostat screen after
the filter has been replaced; use the arrow keys to move the
highlight bar to Filter Reminder.
Press the key below the OK key label in the smart-key label at the
bottom right of the display to select this new information screen. If
you decide to cancel the operation then press the key below the Go
Back key label in the smart-key label at the bottom left of the
display.
The display updates to show Filter Reminder Reset at the top of the
screen and the following message in the center of the screen Your
filter reminder is going to be reset. You will be notified in Months> to change it again. The X displays the number of months
designated at the initial thermostat setup.
A graphic, adjacent to the Filter Reminder, appears to signify that the
Filter Reminder has gone off.
Press the key below the OK key label in the smart-key label at the
bottom right of the display to reset the reminder. If you decide to
