Commonly, operational issues may not be apparent when a system is into a particular operational state via over-riding sensors “forced” # or changing set-points. Utilizing existing BAS Trending capabilities or Stand-Alone Data-Loggers is recommended to capture and verify actual system operation under normal operating conditions.
