Thank you for your quick response! Just to update, all is up and running! The original UNT controllers that I replaced were UNT-110-1's. I replaced them with UNT 111-1 controllers. I pulled the N2 off the terminal block without paying attention to the configuration of the N2 wire colors because everybody knows that red is plus and black is minus right? Not in this case. It appears that the original installer felt that it was better to make black the N2+ and red the N2-. After reversing the leads the controllers came right up. I wish it were a deeper problem, but I have to be honest. Thank you for your response and have a good night!

Thank you!

Please keep the emails in your profiles, TY !!

Everyone else has given you some great advice. Many times issues like this are resolved by going back to basics and checking the details. We work with both Facilitator and Metasys branded devices in our test lab every day and from the standpoint of HVAC Pro they are interchangeable. One thing to be careful with if you connect directly to the N2 bus with the CVT101 or another USB to RS-485 converter is to make sure that no supervisory controller is active on the N2 bus at the same time that you are using HVAC Pro.

The 1st thing you will want to do is make sure that the units are addressed correctly. Each unit that is on the trunk must have a different Address. I am sorry if you have already checked this but you address the controllers by using the dip switches. You use binary to address the unit. There are 3 different set's of dip switches on a UNT so make sure that you are using the set of dip switches with numbers above them. You can look at my profile and e-mail me if would like a manual.

Cannot see the UNTs that I just replaced and programmed...

Make sure your address is correct and that you have power to both the UNT and the CVT101 and then try to download. If you do not have a CVT101 they are not very expensive and will be a very useful tool. Do u have a NAE on the site? If you do you can go through the NAE to load the controllers. If you want you can e-mail me with your # and I would be more than happy to walk you through a few different options. I have loaded thousands of UNT's and most of the time the is an addressing issue or a bus problem. You can e-mail me a chardesty@a-techs.net I am pretty good at troubleshooting over the phone and I can pull HVACPro up and go step by step.

We're unable to download information to the UNT's. We have all the manuals but nothing is working. Does anyone have experience with these components and is willing to help us work through this problem? With all the budget cuts, we're trying not to spend the Huge $'s on a JCI Contractor. Any help would be appreciated.

Thank You very Much & Have a Great Day!

Did you have any luck doing this yourself ? I to work for a small school district and have the same system installed at all sites .

Actually Cagey has it Backwards. The AS-UNT will work with everything Metasys.; Companion, NCM, N30. The FA-UNT works with everything Facilitator; Facilator (a companion Clone), and the Facilitator N31 (N30 Clone). HVACPro will work with either. I do not think the pass through will work with mismatched headend and controller. So a RS485 interface from the PC to the UNT should work.

I know the Facility Explorer is supposed to work with either field controller. (Facility Explorer is not Facilitator btw). I think the MSEA equipment will work with both old systems also, but I am not sure.

The FA- product and the AS- product were exactly the same controllers, but a setting in the chips kept them from working with the other "brand". (I never tried it but I wonder if they would send data if the UNT were mapped as a VND?)

Hi, Robert...it looks like Cagey57 has already asked you a number of the pertinent questions, but if I can be of any additional assistance, please send an email me at Email Address Removed

What version and what is the name of the software you are using. If you actually have a Facilitator you have few options short of an upgrade of both software and possibly hardware.

The FA series UNT should communicate just fine with "Companion" or later Head end devices. However if you are using "Facilitator", which was a supply house version distributed prior too the ABCS program you may be in trouble.

Plese post Part/Model numbers from your software CD (3-1/2" floppies hope not ) and version. You should be able to communicate with the FA-UNT1xx wiith CPN/NCM/N30 with no problems if you are running C-Tools 7.03 or newer. Depends on the PC OS.

Robert, i'm not 100% sure but i dont think hvac-pro will work with the "FA" controllers. I think pro can only be used with "SA" controllers, you might check the other ones on your existing network and see what they are and see if you can talk to them.

Robert, I have relocated your question to a place where you will get an answer, the "Controls Forum" and BTW welcome to the site

Won't Johnson Controls give you any phone support?

Mods I think this beongs in the controls section.
