The OAC-5000-UI has a single-integrated universal insertion probe sensor but can handle up to two universal standoff probes. Compared to the OAC-4000, the OAC-5000 has an additional analog input and analog output. As a result, it can be used with analog CO2 sensors as well as approved BACnet MS/TP CO2 or occupancy counters. It also provides an airflow output signal, if desired.
The OAC-5000 modulates a proportional damper actuator or variable speed fan (VFD or ECM with analog speed control input) to maintain the outdoor airflow rate when an external binary trigger is active (i.e., occupied mode). The binary trigger is typically provided by a thermostat or other analog or BACnet MS/TP binary output.
