Arduino HVAC Controller

When it comes down to selecting a HVAC college program, the first thing that you must find out is that your preferred choice of college you have chosen has the necessary accreditations. This is an extremely important factor, since it means that the training program provided will be at the required standard specified by approved HVAC organizations.

The premier accrediting agency for HVAC training programs is the NCCEA, the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. Select a college that has at least one accreditation.

Smaller class sizes are also important, which means you will get one on one tuition from the program teachers. A good HVAC college will also have an on-campus science laboratory with modern equipment. Visit the campus and get a feel for the place, the instruction rooms, the facilities and talk to the faculty, if they are available. Also find out whether they allow any flexibility in scheduling classes for working students, and how you should go about procuring financial aid, if you might need it.

2 The Comfort Controller product family provides general purpose HVAC control and monitoring capability in a standalone or network environment using closed-loop, direct digital control.

UNT Controller—Unitary Controller (UNT) 7 Configuring the Controller All UNTxxx-1 models require HVAC PRO for Windows. HVAC PRO for Windows also works with previously released UNT models.

The action of the controller must match the proper HVAC application. Normally open heating valves always use direct acting controllers. If a reverse acting controller were to be placed on a normally open heating valve, the heating valve would open as temperature rises.
