FAN OPERATION -
Fan operation is available in four different modes:
Fan:
When only the fan icon is displayed, this 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
(see page 25)
.
Fan , Fan , or 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 thermostat is
placed in the Off mode or a dry contact forced unoccupied time period
(see
page 26)
.
Notes:
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 continuously when the fan is in the Auto mode, but will
de-energize if the thermostat is placed in the Off mode.
MINIMAL DISPLAY -
When the thermostat is programmed for a minimal
display
(step #3, page 18)
, a blank screen will appear. When a button is
pressed the full, normal display will appear for 10 seconds.
