FlexStat (General) 23 Application Guide, Rev S
Displaying Outside Air Temperature
At the boom right of the Home screen is an
area that can display several object Present
Values. In models with the built-in space
relative humidity sensor, the relative humid-
ity is automatically displayed. The outside air
temperature sensor can also be displayed (as-
suming a sensor is aached to Input #4 in AHU and RTU applications).
Firmware R2.0.0.9 and later makes it easy to show and hide relevant
rotation values from the Advanced > User Interface > Rotation Values
menu. See the FlexStat Operation Guide for more information
To display the outside air temperature in older rmware, use BACstage
or TotalControl to do the following:
1. Open up Analog Value object AV23. The default description is “UI
mapped value #2, <~OAT> outside air temp.”
2. Edit the object description by removing the ~ in front of OAT (and
optionally changing OAT to OUTSIDE).
3. Restart the FlexStat.
NOTE: If several readings (objects) are congured to show in the eld,
the values will rotate about every ve seconds.
NOTE: For more information about outside air temperature applica-
tions, see Application Note AN0410A Measuring Outside Air
Temperature on the KMC web site.
Displaying Other Objects
To display another object (not part of the
Rotation Values menu) on the boom right
of the screen, modify Analog Value AV25
and write a value to the object in Control
Basic. For example, to display the Mixed
Air Temperature in the economizer (as-
suming a sensor is aached to Input #3 in AHU and RTU applications),
use BACstage or TotalControl to do the following:
1. Change AV25 Description from “UI mapped value #4, <~UI4> not
used” to “UI mapped value #4, <MAT> Mixed Air Temp” and
congure units for ° F (or ° C as needed).
NOTE: Put no more than 8 characters between the brackets. (MAT
works, but Mixed Air Temp is too long.) Using all capital
leers may look beer on the LCD screen than mixed case.
2. Write the following Control Basic program to assign the Mixed Air
Temperature sensor (AI3) present value to AV25 and congure it to
auto-run:
AV25 = AI3
3. Restart the FlexStat.
NOTE: If several readings (objects) are congured to show in the eld,
the values will rotate about every ve seconds.
NOTE: To hide a display object, add the ~ before the description in the
< > in the appropriate Analog Value object or select Hide in the
Advanced > User Interface > Rotation Values menu of Firm-
ware R2.0.0.9 or later.
