The OAC-4000 modulates a proportional analog actuator or fan speed controller to maintain the outdoor airflow rate. The analog actuator solution allows for larger damper sizes and is ideal for ducted systems to fan coils, makeup air to air handlers, makeup air fans or zone level DOAS applications.
DCV requires approved BACnet MS/TP CO2 sensors or occupancy counters. Occupied mode is typically enabled by a 24 VAC output from a thermostat on fan coil systems or via BACnet MS/TP on makeup air to air handlers or zone level DOAS systems.
