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. Trend measurement sample rates between 1 & 5 minutes or based Change-Of-Value (COV) are recommended over a time period of 2 weeks to include at least one Monday morning following recovery after a weekend.
