Your thermostat also keeps a record of the number of hours your filter has been in use. To maximize your system’s performance and energy
efficiency, change or clean your filter regularly.
NOTE: Clearing the Filter Monitor counter will also clear ALL Energy Monitor counters, as Filter usage and Total
Energy usage are the same. Also, clearing the Energy Monitor counters will clear the Filter Monitor counter as well.
■ When the total system run time for heat and cool reaches 500 hours,
“FILT” will alternate with the current time on the LCD display to remind
you to clean or change your system’s filter. “FILT” will continue to flash
until the counter is set back to zero.
■ Press to review total filter usage. The display will blink “FILT,” then
show the Filter Monitor counter. After 15 seconds, the display will
return to normal mode, or you can hit RETURN to exit immediately.
The Filter Monitor will display up to 999 hours and 59 minutes of usage.
In this example, the counter is at 410 Hours, 26 minutes.
■ To reset the Filter Monitor counter, depress FILTER for 3 seconds.
The display will blink, and the counter will be reset to zero.
