System and approach for validating conditions of a space
A system and approach for verifying and validating a room condition and its behavior in a critical environment. The system and approach may be a room controller built on top of a Niagara™ framework or launched from a Niagara workbench, and leverages extensible of Niagara. The system and approach may be web-based and used to test and verify the room condition per preset conditions. The system may have steps or tabs. They may incorporate screens for a create/open task, select test zone, read flow, hood/booster, T-stat set-up or temperature lever set-up, visual checks, and a report. One may create a new task and edit any existing task on the controller. One may move from task to task in either direction or go directly to the report of a completed task.
