10. 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 PRO-
GRAMMING YOUR THERMOSTAT.
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.
11. Why is the system turning on and off so
frequently (seldom)?
The anticipation setting is too low (high). To
change anticipation settings, see OPER-
ATING YOUR THERMOSTAT.
12. Between heating and cooling seasons, I
want to turn my system off. Can I do this
without affecting my thermostat program-
ming?
Any time you wish to turn your system off,
simply press
SYSTEM
SWITCH
until the display shows
OFF. This will not affect your thermostat’s
programming in any way. To turn the sys-
tem back on, press
SYSTEM
SWITCH
until HEAT,
COOL, etc. is displayed. The system will
automatically begin operating according to
the current thermostat program, unless the
thermostat is in the HOLD mode. See OP-
ERATING YOUR THERMOSTAT.
13. I live in an area where daylight savings
time is observed. How do I change the
thermostat clock twice a year without
affecting thermostat programming?
