To set the BACnet device instance, name, and
location, press:
1. Up
/Down to move among entries.
2. Enter to select.
NOTE: In firmware versions R1.3.0.4 and earlier,
the FlexStat could also be restarted or
restored to factory defaults from this
menu. In R2.0.x, this function was moved to
a separate menu. See (Advanced) Restart/
Restore on page 18 and Resetting the FlexStat
on page 26 for more information about that
function.

Inputs vary according to model, selected application,
and selected application options. See (Advanced) Ap-
plication and Additional Setup on page 7 .
Value will show a temperature reading or a voltage
(0.0 to 3.0), depending on the sensor. Analog sensors
(built-in or external) can be calibrated by adjusting
the Calibration Offset value (see the FlexStat Appli-
cation Guide for details).
Filter Weight smooths (dampens) input value read-
ings, reducing sensitivity to noise and temperature
spikes. Smaller filter weight values (more sensitive)
cause the sensor readings to react more quickly to
sudden changes, and larger values (more stable)
cause sensor readings to react more slowly to sudden
changes. Areas subject to sudden swings of tempera-
ture from factors such as door openings and closings
may benefit from adjusting the filter weight. Tempo-
rarily reducing filter weight may also be helpful for
some diagnostic or commissioning purposes (but the
defaults should be restored for normal operation).
For much more information, see the FlexStat Appli-
cation Guide .
Calibration Offset can be used to calibrate an analog
input by changing the value. For details of calibrat-
ing the internal temperature sensor, see the FlexStat
Application Guide . (A CO
2
sensor has a different
calibration method, using a gas cylinder—see the
FlexStat Application Guide .)
“Out-of-Service: False” means the input is active (not
out of service). If it is “true,” the input is inactive.
The FlexStat menu only shows the status. The status
can only be changed through BACstage or TotalCon-
trol.
