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 Oset 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 lter 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 benet from adjusting the lter weight. Tempo-

rarily reducing lter 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Oset 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

sensor has a dierent

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.
