I'm sure the air balance report was spot on.

Honeywell.....the Goodman of controls......anybody can buy their crap.

What kind of train does he drive?

This would probably get you in the right direction www.ke2therm.com/files/B-1-4_July_2013.pdf

I haven't used it but it does modbus and is pretty inexpensive, the lead/lag you would probably have...

XL-10's go occupied when comm is lost.

Seems to me the bigger question is how did you get Honeywell to open up the license? I hit a brick wall the one time I tried.

There is an enum point in kit control.

Set it to auto.

I've noticed the "made in the USA" controllers we had to get from Honeywell for ARRA projects say assembled in Mexico. I guess the word made means different things when you can afford to hire the...

XL10's are configurable so you can't customize the internal programming.

With something like that I would probably set the DO as a free output and do the logic in Ax.

If you don't have enough straight duct up stream, you can have too much turbulence at the sensor and see this type of issue.

I think the big question is: do you really want to go down the Spyder hole?

There will be an integration module between the asd buss and the micro net buss for the vav's, I believe one for each 31 mn devices. It's been awhile I don't remember exactly what everything is...

I didn't know they made plenum rated OSB.

I just tested one of these on the bench that I condemned in the field. Works on the bench, I think maybe the little selector switch wasn't quite lined up just right, not sure. I don't get a warm...

I've had some luck over the years cleaning boards with distilled water and a toothbrush. All it takes is a little crust or whatnot to short across a couple traces. If it was underwater it may have...

That would be me. After looking at this thing it occurred to me that I never gave much thought into how something like this was being controlled back in the day when I was a service tech. Dusting...

It's all going to be managed by the BAS we are installing, just trying to nail down the best control scheme for the DX.

Thanks for the replies, it's a multizone all new VAV's, DAT will be reset based on demand we will control econo also. Hot gas is already piped also not sure it is really needed but I'm sure we will...

We've got this old building we are retrofitting, the existing Trane air handler with 2 Carrier CU's is staying. Don't have M#'s not sure it would matter after 20 years of hackery not much is...

Maybe something like this would help http://workaci.com/products/arm-analog-re-scaling-module

Why was I expecting to find a joke here?

you will have oil return problems if you try to run a compressor at less than full speed.

A DP switch wired to an indicator lamp of some sort would work.

Looks a little dry.

You answered your own question already....just use Firefox

Not if they are thinking clearly.

You didn't mention where you are located,these guys http://www.hvacx.com/ might be of help.

I assume you problem is displaying the proper units in the browser, sounds like it works in workbench. There is a unit conversion setting for each user in the user service maybe that's what you are...

What are you using the N/C contact for?

It's more like an enclosed roof cavity, but pretty much where the attic would be if there was one.

Found this a a high school, 3 units in this room routinely gets over 100° in summer at this location. Yes this was an engineers idea.

Sika makes a product that produces a porcelain like finish, I've seen it used to coat tower sumps. Don't know the exact name they make a lot of stuff I bet they have something appropriate for your...

You need to set the local lon device in the Jace to external config if you want it to be managed by Lonmaker. Assuming that is really what you want to do.

Might not work so well with tall buildings and <60° temps.

Just park facing the sun and leave your lunch on the dash, toasty by noon for sure.:grin2:

No real immediate need, just want to know for future needs.

Had no luck a electrical supply house and don't want the plates just the adapter ring. Seems like it should be a common part but doesn't seem to be available separately.

I don't even know what to call it, but it's the horizontal to vertical adapter ring that comes with the plastic plates for retrofitting t-stats. I just want the ring though not all the...

Does the fan have a VFD? If so fan status would probably come from one of the status relays in the drive,

Could be the smog....or surly coworkers.

Never knew that, when did they sneak that one in?

This can be done with AX no hardware needed, just run a station on your laptop.

Embedded workbench is a feature that can be licensed, so maybe.

I was thinking with the Belimo.

Something like this would do the trick. Just pick your favorite protocol and tie into your front end when the time comes.

I think lubrication becomes an issue on most compressors when run at reduced speed.
