Filter Change Reminder
If your installing contractor has configured
the thermostat to remind you when the air
filter needs changed, you will see FILT in the
display when your air filter needs changed.
FILT will be shown in the display after your
system has run long enough to require an air
filter change.
Resetting the filter change reminder: When
FILT reminder is displayed, you should
change your air filter and reset the reminder
by holding down the second button from the
top left side of the thermostat for 3 seconds.
Understanding Thermostat Staging
Your thermostat will control two stages of
heating. The thermostat will try to maintain
your comfort setting using the first stage for
energy efficiency. The second stage of heating
will only be used if your thermostat cannot
maintain your comfort setting using only one
stage. When the second stage is used you will
see +1 in the display.
Hold down for 3 seconds,
to reset filter reminder.
