Models
If your application is a:
◆ FCU (Fan Coil Unit) or Packaged Unit, AHU (Air
Handling Unit), or RTU (Roof Top Unit)—see all
models
For more details, see Application/Model Selection
Guide on page 4. See also the FlexStat Catalog Sup-
plement and Selection Guide (SP-091)!
◆ HPU (Heat Pump Unit)—see the BAC-1xxx63CW
models only
Model* Outputs** Optional Sensors*** Typical Applications
BAC-12xxxx models (e.g., BAC-120036CW) are standard and do not have a CO
2
sensor. BAC-13xxxx/14xxxx models (e.g., BAC-140136CW)
have CO
2
sensors to add Demand Control Ventilation to the applications below. DCV is only available when using an AHU, RTU, or HPU
application with a modulating economizer option enabled. See “Specifications, CO2 Models Only” for more information.

*The standard color is white. To order the optional light almond color, remove the “W” at the end of the model number
(e.g., BAC-121163C instead of BAC-121163CW). To order the IP version, add an E after the C (e.g., BAC-121163CEW).
All models have a real-time clock.
**Analog outputs produce 0–12 VDC @ 20 mA maximum, and relays carry 1 A max. per relay or 1.5 A per bank of 3 relays
(relays 1–3, 4–6, and 7–9) @ 24 VAC/VDC.
***All models have a 32-bit processor, an internal temperature sensor, and 6 analog inputs. All models have optional discharge air
temperature monitoring/trending and fan status monitoring. Optional sensors include humidity, motion, and CO
2
.
****In models with CO
2
sensors, humidity sensors come standard.
