Unfortunately, it doesn't matter if the CCN router is not tied into the I-Vu Server yet, as the driver in the CIV-CR could be a 6.0 driver
causing the problem.
Try downgrading the router driver...
If you have not lost your hard drive yet,
I recommend that you buy a duplicate hard drive, and use a hard drive clone software package, and make a replicate of your existing hard drive, before it...
Lots of questions to ask before I can help;
1. This sounds like a new installation; is this a "I-Vu 6.0" Open project or an "I-Vu CCN 4.2" Project?
2. Your CCN sub should be able to give you a...
The Carel pco2 controllers are used by many HVAC equipment manufacturers internationally under usually an "OEM"
relationship. This usually means that you will likely not get access to make much in...
Wow this could get long;
Belimo - Actuators for almost anyone with a checkbook
BAPI - sensors for almost half the big's
ACI - same thing as BAPI
Honeywell - makes many of the velocity...
I am not sure it this helps but I did find this in my Translator documentation folder:
Issues addressed in this release of 1.4 software:
1. BACnet Writes that do not include a priority are now...
Both Crab Master and BACnet>CCN are correct, yet there are still other considerations.
ALC/Carrier and many other controller brands today, have engineered comm port "connection chips" that...
Attached is a basic beginners course on Direct Digital Controls for HVAC.
Based upon the simple why you asked the question, may I kindly suggest that
you take a bit of time and review this...
Good job trouble shooting, I don't think anyone of us on line hear would have found that thru our keyboards
I guess I didn't ask my question correctly. I am aware of the fact that the ALC ZN product line can reside on
a BACnet MSTP 9,600 bps thru 76,800 bps communications buss.
I am wondering, did you lower the ARCnet buss speed down to work with the CC Gateway?
The CC Gateways are really easy to work with, but I don't recall that they supported 156k baud
Pick on my profile, my contact email is there. Send me an email so I can send you some information I promised.
It is not appropriate to put ANY email addresses into these postings, and I do...
No Honeywell not needed but a zoning system is such as the carrier infinity zoning system
here is a link...
You answered exactly why I was concerned with the humidity control first; you have expensive custom wood working that needs
accurate control of the humidity system, and if that goes wrong,...
Good for you; you see the big picture already; MAKE THIS WORK, and REALLY GOOD!
Often the AV and HVAC guys are at odds because the AV techs really love AV systems and think HVAC is easy,
For you WebCTRL ALC guru's out there;
I have been testing some customized war files. I see that there was a localized lock down to
"local host" loading of war files in the latest WebCTRL...
Sorry it has been a while since we chatted,
Maybe I am getting old and decrepit, but please expand on the ISO and ANSI device's description.
I thought that ISO and ANSI were specifications? ...
Wow, seems that there may have been some "questionable integration decisions" made early on.
Depending on which Crestron network interface controller is being used, and the electronic...
Time and date sync will likely be non operational between the WebCTRL Server and the ALC Modules on the ARCnet buss.
Doubt that the thermo graphic color data packets would reach the server, or the...
VVT Controller IOM:
PowerPoint training files will not upload to this site, so email me if you want them.
Good luck, it sounds like you know what you are doing.
BACnet is correct and brings up a good point; and I was wondering why your bypass static "set point" is so low?
(I have seen techs set this low to cut down on the famous carrier VVT zone noise...
The fact that your minimums are set around 20% reduces the potential of the PAT versus DAT sensor location on the zones.
(with that amount of minimum airflow, the sensor would be reading what SAT...
Low suction temperature or pressure?
Also check page 61-62 of the 38 IOM
Sorry, forgot to mention a bit about the VVT PAT sensor;
(I noticed you stated that the VVT zones were sensing DAT "locally")
Where are your VVT zone PAT (DAT) sensors located, before or after...
Just some items to consider:
1. Sounds like the SNAP programmer may have known (or found out the hard way) that the earlier versions of "SNAP" "Open linkage" just flat out did not
Ignorance on the part of the author of such poorly designed specifications.
I usually find these type of poor specs authored by very young and "partially trained,
yet substantially "less than"...
The feature "Unoccupied Fan Cycling" with a default of 1 minute is for running the indoor fan for moving the air around a little so the unit can get a sense of the space conditions to calculate...
Is the RC642 Room Controller still available?
Seems that last time I checked it was a BACnet controller that looked like a Tstat,
yet had flexible program logic.
I am not a ALC dealer so I may...
Is this a i-Vu 6.0 "Open" FCU Controller (Carrier I-Vu Part number would be "OPN-FC")
or a old CCN Fan Coil Controller (Carrier Part Number 33ZCFANCOL)
mapped in on the...
Did you do a "bbmd read" on the ALC LGR to see if it has a BBMD Table in it?
Additionally, what version of ALC hardware drivers (Exec B?), and ALC Software (WebCTRL 2.5, 3.0,4.1, 5.2)
Actually in California, that employer's payroll staff did it the correct and legal way per CDLRB rules.
I have seen many a California Controls contractor (and HVAC and Electrical) pay the wrong...
If I recall correctly, once you have made your ".equipment files" in i-Vu 6.0,
you can not load them into a i-Vu Link 4.2. ( I think I tried this a while ago and
it was a "No Go".)
Cool, sounds link you are having fun. Smells data center "ish".
There are some great free BACnetIP and Modbus TCP sniffing programs out on the WWW.
It would be very cost effective and easy to...
Did you get your information above using a "BACnetIP" data sniffing program?
It would appear that the points you are looking to "poll" are inside of an ALC LGR 1000 router and
depending on how...
You are the absolutely BEST and Smartest HVAC / controls tech ever!! NO one here would have ever known
how utterly bad Carrier Controls are, unless you told us.
Get together a simple straight forward brochure that tells exactly what you do "Install controls"
(have real references from others that like your work)
Next go and meet with every...
Which brand and which powerline frequency topology are you looking for because the technology has changed with some different twists (all for the better) and there are many different manufacturers...
Usually when I see a "Carrier i-Vu Open" "AppController" used instead of a "OPN-RTU" controller it
spells "custom programming inside". This can mean that there may be customized programming logic...
What you described is what I have found in almost every "conditioned facility" I have worked in over the last 30 years.
Men and women, it doesn't seem to matter, you described what a great majority...
Great questions. With over 500 different BACnet systems out there, and almost all having a bit different
front end / or IP/MSTP router set up, it would be almost imposible to provide you any...
Heating and Cooling Setpoint Minimum Separation?? Wow, a subject that chaps my aaa ssss!
Unfortunately, the "up and comming" automation system programmers I have been dealing with
for the last...
MSTP/EIA485 is usually fairly simple to trouble shoot, yet different manufacturers all have a different way of
"managing the MSTP adjustables", and this often can cause issues with MSTP...
If your email address is still good, I will send you some operational, and editable, SNAP integration
programs. You can add as many points as needed of each type using your SNAP.
The number of CCN points are not that much. For getting this data over to Tridium, you could use an i-Vu Open Link
with one i-Vu Open UPC connected to each chiller (or CCN device, your budget...
I am slightly biased towards products you can get without being a "licensed dealer or distributor",
and those that are easy to have my end user clients learn. With that in mind here is...
Are you familiar with soap and xml pipe feeds?
Seems like you could aim a custom excel based soap / xml data pipe feed at the clients web based schedule xml objects,
(if they can be, or are...
i-Vu 6.0 is likely to be out in August this year and it will support most browsers regardless of OS;
Safari, Fire Fox, Chrome, at least that is what I have been told.
Maybe a simple wall switch and the owner's secretary? When she get's hot, guarentee, she will hit the switch.
Sorry, that will not be a reliable control setup.
Actually, there are many dual...
Excellent! Looks like the tables were scanned in also.
Here is what the i-Vu CCN 4.2 Application Builder integration program would look like:
I can email you the actual program if you...
Just what I thought. I can almost guess that the Link you have on the site is a i-Vu CCN Link.
All you would have to do on your network tree is right pick on the "Gateway" and select
