different modes:

indicates that the fan is in the Auto mode, will only
energize during a heating or cooling cycle, and will
modulate fan speeds based on temperature demand

Fan
: Pressing the FAN button
will cause the low, medium, or high speed fan icon to
appear
(see page 11)
, indicating that the fan will run
continuously. The fan will de-energize if the thermo-
stat is placed in the Off mode or an unoccupied time
period
(see page 26)
.
1) If a Duct sensor is connected to this thermostat,
then the fan should be programmed for continuous
operation (step #7, page 20). This will provide airflow
over the Duct sensor and provide more accurate
temperature readings.
2) If the fan is programmed for continuous operation
(step #7, page 20), the low speed fan will run contin-
uously when the fan is in the Auto mode and during
occupied time periods, but will de-energize if the
thermostat is placed in the Off mode.
Notes:
MINIMAL DISPLAY - When the thermostat is program-
med for a minimal display
(step #3, page 18)
, only the
time of day will appear. When a button is pressed the
full, normal display will appear for 10 seconds.
