By the way, if you do ever need the ability to sniff a PUP network let me know. I wrote a small computer program to do that and then decode the results into plain english.

I'm sorry to read that your local rep. I hate that, and have to deal with it myself on a regular basis. Not with AAM reps, with others; JCI, Honeywell, Carrier, etc and so forth.

Anyway, I see by...

I hope it works out for you.

In your original post you mentioned that the "FS-1" failed. I think you meant SF-1.

I don't know if those are still available. Might be hard for AutoMatrix to get...

Well, I don't know how your system was set up in the first place.

But let's try some guesses which you should be able to verify.

Chances are that the DX was set up as an Irresponsible Peer?...

The driver costs a thousand? Interesting. I myself have never personally ordered any of the Jace stuff. It's usually done by the office staff. And I haven't had an occasion to be curious and look in...

LOL ... Well, I often find myself in the position where I WISH I had a system that was partly the best of System A, and partly the best of System B ... and then toss in a few odds and ends that...

Well, I know little about JCI's FX Jace, specifically. Last one I saw we ripped out and replaced. Nothing wrong with it, just a matter of a customer fed up with the local JCI contractor. I'm not...

Actually what I get out of this thread, and what I have gathered in real life talking with various guys I've dealt with in the field goes about like this:

1. If it's a person who actually knows...

Well, I've worked with Jaces, but not the R2 versions. And I've never seen the data for an AAM device displayed the way you've shown it.

However, I can make out what it says.

65280 System...

Yep, showing that extra precision can be problematical. And makes no real difference to human comfort. OTOH, with some occupants, if they can see that value to the right of the decimal place, it can...

Well, I am hardly familiar with all possible CO2 sensors one might buy and use.

I have used a LOT of two of the specific lines mentioned here. The QEL and the Veris units. (Veris both under their...

Yeah, I hate it when that happens. I have more problems with the fitters/plumbers (depends on which site/area) getting things out of whack than I do with anyone else. i.e. Our guys who do the wiring...

Hmmm ... pretty much for the past 12 years that I've worked with them, the single screw attached Belimo valve actuators have taken 1 of TWO different thread diameter screws. Either M4 or M5, IIRC...

Yep, I pretty much agree with Orion.

I've known and worked with controls techs/engineers who insist upon tight control/fast response. Which means frequent, small adjustments.

And I've replaced...

Yeah, I have some experience with them.

But I'm not inclined to try to analyse your problem as I know nothing about JCI equipment. At least none produced since 2000.

Can the firmware of the...

Yeah, we've done custom 3D views for a few projects. Very time intensive, as compared to regular 2D layouts.

The truth is ... it's the customer upper management and executives who get wowed by it...

Yep, I didn't mention it but we INSIST upon good labeling practice. All our installers have the good label makers, and tape, which can turn out labels for devices and boxes, and labels suitable for...

Nice training video.

However, I always tell any new installer we get to NOT cut the jacket away as shown.

If one is careful and does it right, it works 99.90% of the time. But I find that...

I'm not quite sure what you mean by "detecting issues with the VFD through the BMS".

This thread was/is generally about what method folks thought best to use as proof of air flow, a mechanical...

Hmmm, okay Thanks. Always good to know this sort of thing, even if it hasn't been my own experience.

Now, while we've used the precise devices you show, a great many of them, none are installed on...

Do you really think so? Maybe things work differently where you are as compared to where I am. I've known a few ... DARN FEW ... IT types who successfully made the jump into building controls. But,...

Nope, haven't made the retro move. Although I'm not sure I personally think of it as a "retro" move. When you call it something like that you make it sound as if a controls guy is necessarily...

Hmmm, interesting. Care to mention which make of CT's you see fail the most?

I only ask because I myself don't see many of them fail. OTOH, I don't see many mechanical air flow switches fail,...

Well, it's like a lot of places these days. Pretty common to walk into a Radio Shack, or a hardware store for that matter, and find that they have precisely 1 person on staff who has a clue about the...

Yep, download the data and operate off that. My point was that sometimes things go wrong with an internet connection, or with the site you're trying to access for some data. So relying on continuous...
