The Air Filter Monitor counts the duration of filter usage that has occurred,
since the last time the Filter Monitor has been reset. This feature is for
information purposes only, and does not affect the operation of your heating
or cooling equipment, or the thermostat. When the filter usage duration has
expired, the words “CHANGE FILTER” will appear at the top of the display
screen, alternating with the current DAY and PERIOD.
TO ACCESS FILTER INFORMATION: Press the MENU button, then press the
SCROLL button until “SET/REVIEW FILTER USAGE” is shown, then press the
OK button. The words “FILTER USAGE COUNT” will appear at the top of the
screen, along with the total number of hours that have elapsed since the last
time the filter counter was reset. Press the NEXT button to advance.
The words “FILTER USAGE RESET?” will appear at the top of the screen. To
reset the filter counter to the start of the current limit setting press the OK
button. Press the NEXT button to advance.
The words “ADJUST VALUE FILTER LIMIT” will appear at the top of the
screen. This shows the current setting value for how many filter run time
hours can elapse before showing “CHANGE FILTER” in the Normal Run
screen. The adjustment range for this setting is from 0 hours to 2000 hours,
with 720 hours as the default. A filter limit setting of 0 (zero) hours will
disable the filter monitor feature. Once complete, press the EXIT button to
save all settings and return to the Normal Run screen.
NOTE: Air filters are sold based upon how many days they are rated for. One
day of filter run time is actually considered only 8 hours (not a full 24, since
your heating and/or cooling system only runs for approximatly one third of
the time). For a “90-day” filter, use a limit setting of 720 hours should be
used, and for a “30-day” filter, a limit setting of 240 should be used.
ENERGY USAGE MONITOR: Your thermostat contains a timer, which records
the amount of “on-time” for your heating and cooling systems. There are
three records that can be displayed for both Heat and Cool modes:
1) The amount of system run time so far for today.
2) The amount of system run time for yesterday.
3) The total cumulative system run time since the timer was reset.
