### Asset Description:
VAV: Variable Air Volume (VAV) system regulates airflow volume—not just temperature—to maintain comfortable conditions in different building zones. Unlike Constant Air Volume (CAV) systems, which blow a fixed amount of air at varying temperatures, VAV systems vary the amount of air delivered while often keeping supply air temperature steady

### Conditions:
- Parent AHU Running
- Zone Temperature Setpoint > 75

### How long the conditions were met:
Met for 3 Hours

Analyse the given conditions of the presented asset and select the option that MOST likely gives the reason for the conditions?
A. The condenser water pumps are flowing water through a chiller that is off
B. Review of Boiler Operation
C. Check the logic in the BMS to see how it is set up
D. Validate damper is not stuck closed or open or in between


# Answer

Answer: C. Check the logic in the BMS to see how it is set up

Guidance Rationale: 
 The Variable Air Volume (VAV) system is designed to regulate airflow volume to
maintain desired conditions across different building zones. In this case, the
parent AHU is running, and the zone temperature setpoint is above 75°F, yet the
system has failed to achieve the desired temperature for 3 continuous hours.
This sustained mismatch suggests that the Building Management System (BMS) may
not be correctly coordinating the VAV’s response—such as adjusting airflow or
triggering appropriate cooling inputs. 

While mechanical issues like a stuck
damper (Option D) are possible, the broader control logic is more likely at
fault given the persistent and systemic nature of the behavior. The condenser
water pumps flowing water through a chiller that is off (Option A) would
typically affect cooling capacity but not necessarily the airflow regulation,
which is the primary concern here. Reviewing boiler operation (Option B) is less
relevant as it pertains to heating rather than cooling or airflow management.
Therefore, the most plausible explanation is to "Check the logic in the BMS to
see how it is set up."
