Turns out the modbus card was bad, but now that I have a new one it isn't working either.

Uniflair is owned by APC/Schneider now so they have better documentation on their site -...

One I didn't program, then it's someone else's problem. :grin2:

For ones I've worked with so far I like the TAC Xenta 700 series the most (LON), but I don't like the proprietary...

Rolo would disagree. Also I don't think Siemans can talk proprietary comms.

Welcome to the site.

I must of gotten a hell of a deal on my touchscreens. Oh there the same as grgjohno mentioned.

Briefing the document and going back to the OP, IMO the most versatile setup would be CO2 and IAQ or just VOC.

Interesting concept. Wouldn't the supply air be just as mixed as the return air and even more so once you mix in outside air? Possibly with VAV's closing down/going to a minimum position there may...

FWIW - I just got done installing a wireless network about a month ago and I am pretty happy with the results so far. Granted only doing temperature monitoring at this point, but it was nice how...

I'd suggest a small UPS or other power conditioning/protection device. I'd assume the UPS solved ac-inc/Mike's issue as the last time he was on the site was a day after he posted in this thread....

As stated previously it may make more sense to go with a gateway if the brand of equipment has such. We've done a number with Cat, Detroit Diesel, others and with a gateway you can get so much more...

If I remember right you also really liked this - http://www.opensystemsproducts.com/MODERN/Itemdesc.asp?ic=NRC1C-01&eq=&Tp=

I'd appreciate a PM as well.

I used to have greater respect for Belimo until they sold us a bunch, like over 150 actuators, that were labeled wrong by the factory. We installed every single one of them and didn't realize they...

Have you emailed their tech support/looked on their forums? http://csimn.com/CSI_pages/tour6.html

I haven't worked with that controller, but emailing tech support they were generally back to me...

It would take at least a couple 511's. To follw rules more like 6, but if done with care one could do 2-3.

These were pretty easy to run - http://us.idec.com/Catalog/ProductSeries.aspx?SeriesName=IDEC_SmartRelay&FamilyName=Programmable_Relays
Don't recall cost but it seemed reasonable. I see they have...

I don't know Trend, but I would think it would be more cost effective to just have the customer buy the TAC Vista Workstation license and just add to that. Granted you said the client doesn't want...

The first one, less to wire. :grin2:

Either would be fine, it's just the 2nd one it is hard to see the details. Also I'd recommend using either larger dots on wires that are going to the same...

We use the APC BMS - Battery Monitoring System. We've had some problems with false alarms on Thermal Runaways, but I believe I heard it was due to poor connections and some crimp issues on certain...

Pretty decent overall but I gotta say I hate it when people get their greasy fingers all over in the sticky electrical tape. It just makes it come unraveled that much faster. Pull out an inch,...

Definitely plugged in to serial port, same location as our Stulz units, only those have lon cards. I don't know the part number off hand on the modbus card.
Stulz units also have Carel...

What about a simple pressure transmitter?

No sure if they are looking for minor breaks, but a major break you'd have a pressure loss.

Well no go on this, got a scanner and nothing matched up. At first I though I was able to match up the # of starts, which isn't even in the list, but when I went back later to recheck they no longer...

I hope to make it next year and hopefully see everyone then, unless in a training class somewhere.

I checked out the DG stuff a few years back, but that was as far as I got.

The USB thought is a good idea, I may look into this closer, but we also need something we can read live data from at the time as well.

Bringing this back up as I am looking to implement a wireless solution for recording load data prior to the control system being built. Basically building and unit operation prior to TI.
Just need...
