HOLD

. This sequence of keys will lock and

unlock all settings and programs. When locked,
a padlock icon will be visible
above the time / temperature
area of the display.

7.2 FILTER MONITOR

• Your thermostat will warn you that your HVAC
system’s air filter should be changed by
displaying

FILTER

in the time temperature display

area, after the system’s fan has run the number
of hours specified by this limit.

7.2.1 FILTER USAGE

To view the number of hours the thermostat has
activated the fan since the last timer reset:

AIR FILTER

position. The

current filter usage will be shown with

HRS

FILTER

• To reset the timer to 0, press

between 0 and the current value. The value in
display when you exit this mode will be the value
retained in memory. Leave the value at 0 to reset
the timer.
• To exit 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 2000 hours.
To set the number of hours of filter use before
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 filter’s recommended life. If given in days,
multiply by 8 to find the recommended setting in
hours of filter usage.

programmable and may be changed. See
ADVANCED FEATURES. If you move the heat set
temperature too close to the cool set
temperature, the cool set temperature will move
away from the heat set temperature to maintain
the Dead Band. Conversely, the heat set
temperature will move if you adjust the cool set
temperature too close.

NEXT

to accept and advance to the next period.
