I just came across your channel, thank you for your videos. Do you answer questions as well?

[@MEPAcademy]

Yes, we try to answer as many questions as possible related to our content,

[@NROhvac]

@@MEPAcademy good, Do you guys have online training for wiring schematics with controllers, jace, master jace, and AHU system(general hvac system). I want to learn the controls from the very jace, to the controller, how that communicates and how the ahu is controlled thru the controller (wiring with signal inputs and outputs). Also how the relays are controlled thru the controller and primary voltage. I have a lot of learning to do, I will even pay for a class. Thanks

[@MEPAcademy]

@@NROhvac We are currently developing several training classes for online courses in the MEP trades, unfortunately early release would be around May.

[@NROhvac]

@@MEPAcademy I look forward to may!
