The OAC-3000 modulates an MP-bus network actuator to maintain the outdoor airflow rate. The MP-bus solution is the most cost effective method for actuating small air valves and dampers on ducted systems to fan coils, makeup air to air handlers 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 system.
