Where to buy a wall mounted air handler simulator
I would like to buy an air handler simulator for my company's training room to do practice controls programming and troubleshooting. I know there are a plethora of great graphical simulators out there, but I have some old-fashioned customers and techs that I believe would do far better by hands on with an old-fashioned wall-mounted simulator. Any suggestions on who to contact or where I can shop for one? Any and all assistance would be greatly appreciated.
