AIR FILTER MONITOR:
In most systems that use a blower fan and air
ducts, there is an air filter that is either replaceable or requires cleaning.
The filter is usually located in the air handler, where the blower fan is.
This thermostat feature assists you with keeping track of proper
maintenance and/or periodic replacement intervals for your system’s filter.
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 completely expired, the word “FILTER” will flash on
the screen.
TO SET THE AIR FILTER DURATION: Move the Set Slide switch to the
“AIR FILTER” position. The word “DAYS” will be shown on the screen,
along with the word “FILTER” and 2-3 characters at the top right corner of
the display. Press either of the UP/DOWN buttons to select the desired
filter duration (in days) from the following choices: OFF, 30, 60, 90, 120,
180, or 365. If the filter duration value is set to “OFF”, then the Air Filter
Monitor will be completely disabled. Return the Set Slide switch to the
RUN position when you are finished.
TO RESET THE FILTER USAGE COUNTER: Move the Set Slide switch to
the “AIR FILTER” position. The three small digits at the top of the screen
tell you the quantity of filter days remaining. Press both the UP and
DOWN buttons together, and the usage counter will return to the
beginning of the value that it originally started counting from. Refer to the
previous paragraph, should you wish to change the starting value for the
filter monitor. Return the Set Slide switch to the RUN position when you
are finished.
