Adding a Remote Temperature Sensor to an Input
For space temperature, the FlexStat uses an internal sensor tied to Ana-
log Input #1. However, a thermistor can also be connected to one of the
extra inputs (2 though 4 and 7 through 9) as a remote room temperature
sensor. (Not all applications may have extra inputs available—see the
Sample Application sections.)
In the
BAC-12xxxx/13xxxx/14xxxx
FlexStats with
six external
inputs, the
Input 7 sensor (AI7) can be configured for a remote space temperature
sensor through the menus. Then space temperature can be configured
for onboard (internal AI1), remote (AI7), averaging of the two, the low-
est reading, or the highest reading.
Sample Custom Applications
In
BAC-1xxxx
FlexStats with only
three external
inputs, to have the re-
mote sensor’s value shown on the FlexStat display instead of the internal
sensor’s, do the following in BACstage or TotalControl:
1. Configure the original space temperature AI1 object to “Out Of
Service.”
2. Configure the input for the added room temperature sensor input.
(Type III is the default thermistor type for AI2–AI4 and AI7–AI9.)
3. Add the following Control Basic program. (In this example, the ap-
plication has input #2 open—use another input instead as needed.)
AI1 = AI2
4. Restart the FlexStat.

To use a
temperature sensor connected to another controller
, see
Using
Sensors Connected to Other Controllers on page 15
and use additional
code to map the remote sensor’s present value to AI2 (or other appropri-
ate input).
It may take a minute before the remote temperature starts displaying
correctly. To calibrate the sensor, see
Calibrating a (Temperature) Sensor
on page 12
and use the appropriate input.
NOTE: The Home screen can display temperatures from –99 to
999 (with firmware version R1.3.0.8 or later). Temperatures
between –9.9 and 99.9 degrees can be (if enabled in the User
Interface menu) displayed with tenths of a degree.
