Using a JCI VAV Controller as a UNT Controller.
I was woundering if it was possible to use a JCI VAV Controller as a UNT Controller with a UNT program. All the I/O is the same and i tried opening the UNT program in HVAC-PRO and saving it as a VAV but it would not allow me to.
As far as I know,
"It Can't be Done". That is not the answer you wanted is it ?
If sense were so common everyone would have it !
Any advice provided is worth exactly what you paid for it, not a penny more not, a penny less !!
Haven't done this in a while,I think You need to save file as a UNT.Then change the .PRN file back to VAV.It's a pain.I have a file somewhere on the exact steps.Let you know when I find it.
I think - you can use a custom program which someone has develope to create your own programs. If you search this site, I believe it's someplace here.
