Applies caller-selected thresholds to supply/return temperature differences, com
Applies caller-selected thresholds to supply/return temperature differences, commanded operation, fan state and electrical power. It identifies rule violations in supplied observations only; it does not connect to building controls, establish root cause, replace commissioning or authorize maintenance actions.
