Building Automation HVAC - DDC Controls Retrofit of Standalone Thermostat

If the building had a central plant (Hot/Chill water), the reasoning is the MDF/IDF's will always be served/cooled, regardless of the occupancy schedules, or whether the BAS is knocked off line, at least that is my understanding.

As a verification/pre-commissioning tech at my previous job, I noticed in the school buildings I was involved with the following. In almost every case, the MDF/IDF rooms' systems were stand-alone (not connected for CONTROL to the BAS) but, the BAS in almost every case DID have a monitoring sensor. I know this is nice little project to demonstrate techniques, but the advantage for you as the space occupant will be. . . ?

Good video. Believe it or not, an 18k btu unit wouldn't be considered as an oversized unit for a server closet at the school board. The dehumidification feature will keep the humidity in check. The school board is full of server closets. We recently put in a 3 ton Toshiba mini split to cool a 10 X 10 server room.
