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- STAT.

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.

13.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.
