7.2 FILTER MONITOR
Your thermostat can alert you that your system’s air filter
should be changed, by displaying
FILTER
in the time
temperature display area once the system’s fan has run
the number of hours specified by this setting’s limit. The
presence of the word
FILTER
on the screen will not effect
the operation of the thermostat. If equipped, the filter is
located in your heating/cooling equipment.

activated the fan since the last timer reset:
●
Rotate the dial to the
AIR FILTER

mode, rotate the dial to another
position.
7.2.2 FILTER LIMIT
This general rule will provide you with a good estimate of
your filter’s life in hours. Assume that the fan will run at
1/3 duty cycle or 8 hours per day. Common 90 day filters
are then good for 90*24/3=720 hours of use. This is the
default limit value. Setting the filter counter limit to 0000
will disable the change filter indicator. Valid entries are
from 0 to 2000hrs.

replacement is indicated:

Rotate the dial to the
AIR FILTER
position. The current
filter usage will be shown with
HRS FILTER
●
Hold
NEXT
for 2 seconds. The Filter limit will be
displayed.
●
Refer to your Air Filter package to determine your
filters recommended life. If given in days, multiply by 8 to
find the recommended setting in hours of filter usage.
●
Use

keys to adjust the filter limit in 10 hour
increments to the recommended value.
●
Rotate the dial to
