12. Why does the blower fan keep running
after the system has turned off?
• You have programmed the fan to run
continuously during this period. See
PROGRAMMING YOUR THERMO-

• The blower delay feature is operating.
This energy saving feature continues to
blow conditioned air through the ducts
after the system has turned off, rather
than letting the air dissipate.

frequently (seldom)?
The anticipation setting is too low (high). To
change anticipation settings, see OPER-
