: Pressing the FAN button

1) If a Duct sensor is connected to this thermostat,
then the fan should be programmed for continuous
operation (step #5, page 11). This will provide airflow
over the Duct sensor and provide more accurate
temperature readings.
2) If the fan is programmed for continuous operation
(step #5, page 11), the low speed fan will run contin-
uously when the fan is in the Auto mode, but will

MINIMAL DISPLAY - When the thermostat is prog-
rammed for a minimal display
(step #1, page 10)
, a
blank screen will appear. When a button is pressed
