(Advanced) BACnet Device Properties

INSTANCE:
NAME: FlexStat_101
LOCATION: KMC Controls
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
Restore on page 18
on page 26 for more information about that
function.

(Advanced) Inputs

INPUTS
1: SPACE TEMP
2:
DISCH AIR TEMP
3: MIXED AIR TEMP
4: OUTSIDE AIR TEMP
5: SPACE HUMIDITY
7: REMOTE SPACE TEMP
8: AI_08
Inputs vary according to model, selected application,
and selected application options. See
plication and Additional Setup on page
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
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

FlexStat Appli-
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
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
Application Guide. (A CO
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.

(Advanced) Temp. Setpoint Limits

OCC MIN CLG:
OCC MAX HTG: 80° F
UNOCC MIN CLG: 66° F
UNOCC MAX HTG: 80° F
MIN SETPT DIFF: 2° F
This menu permits changes to the minimum and
maximum allowed user/operator setpoint values.
NOTE: For Minimum Setpoint Differential, see the
diagram.
