During Acceptance Phase, who is responsible for P to P Review Controls?

• A. CxA
• B. Shared
• C. CxP
• D. CxT

Answer: (D)

P-to-P testing during acceptance focuses on verifying the wiring and signal paths between points in the control system—making sure sensors, controllers, actuators, and the BMS are connected correctly and respond as designed. This is hands-on field work that requires following test procedures, recording results, and confirming that each point-to-point relationship functions properly before the system is accepted.

The person responsible for performing and documenting these checks is the commissioning technician. They execute the point-to-point verifications, confirm that each control loop operates as intended, and log the outcomes for review by the commissioning authority. The commissioning authority oversees the process and ensures the tests meet the project criteria, but the day-to-day P-to-P verification is carried out by the CxT.
