I have a 100% OA ERU that operates constantly on an occupancy schedule. There is no Outdoor airflow monitoring device on the unit and no CO2 sensors for the densely occupied spaces. Although as per ASHRAE 90.1-2007 6.4.3.9 Exception a. we don't need DCV due to energy recovery hence no CO2 sensors required.
Also, since this is a 100% OA system, the unit capacity is based on a constant airflow, meaning it will provide a minimum airflow based on the occupancy schedule input at the BAS, and the BAS will generate an alarm when the conditions vary from design value.
My question is - How am I supposed to fill the form when it doesn't give me an option to complete the form without checking the CO2 sensor and OA measuring device boxes?
