When dealing with 'Clean Rooms' of any importance it is best to look for a system that you can interface with that is made to the extreme sensitivities the customer requires. Depending on the extent...

Heh I didn't want to open with that... but WORD.

Coming from working with dedicated Controls Contracting companies, I kinda feel that way about any controls line you can buy over the counter at...

Hmmm... if you want to learn IT and Networking and you are going to the community college to learn it... seems backwards.

Get on Google and start learning for FREE and at a faster rate than any...

My favorite is the RIB relay which is so neatly curled up with a zip-tie and has proper use of wire nuts... Shame they mounted it and never used it or connected it to anything. LOL

The above book: Building Automation Integration with Open Protocols is cheaper on Amazon > http://amzn.to/1ssodcV

Also this book IS much newer than the Gray Manual, but is still dated at 2009 for...

Your company needs to decide if they want to become a Dealer or Reseller of a particular controls line or just Service various controls systems.

If you just want to service existing controls then...

A bit off topic, but I have learned over the years that those starting in Controls work show up to their first job or job site with a SET of these...
...

The programming in all controls is still proprietary so you would need to get access to the system through Orcaview and take a look at the GCL Programming (PG Object) and read what actually turns on...

But price DOES matter and I would never spend $500+ on a multi-meter. If it requires all that then the company should be providing it to me.

I have spent my entire career using a meter that costs...

Here's some extra information from the Delta Controls side.

Delta Controls can implement BACnet one of two ways over Ethernet or IP. With only one DSC1616, I would be willing to bet this panel was...

Just curious... since you labeled this post with the word BACnet... Is there an IT person saying you are bogging down his network with your 'Air Conditioning Stuff' ?

You can usually run a...

Thanks for your link and insight, Kevin.

I will delve more into how to implement this.

Here is a little example of what I am thinking and trying to accomplish...

This is what I am currently working with...

I admit I have not been involved much with Tridium so I am unclear exactly what is needed to create some cool custom graphics to help brand our graphics to our customers.

I need someone to explain...

Actually... don't be so harsh. The top replacement panel isn't, as you said, more than just a new non-Novar head-end, but the transition board below it has a few little tricks and improvements. One...

It's Spring time... Don't forget to plant early before it is too late!

I can tell by your post you are a bit new to controls, correct?

Whatever you are working with has a controller that has programming in it and you have to understand what was programmed to know if...

Eh, I think getting bids and looking at the costs is the LAST thing you should concern yourself with, but we all know how the people who count the money or make the final decisions REALLY think.

This is a really old thread, but lucky for you GCL hasn't changed from 5 years ago. I have most of my 16 years experience programming and engineering Delta Controls systems. Is there not many people...

Well if your current contractor is an Alerton dealer/partner and you are satisfied with his work it would make sense to continue to go with Alerton if you are accustomed to the brand and can get the...

Just curious what kinds of facilities are you working in that utilize LON? ...and as a contractor or on-site staff?

I don't see any LON stuff in the few states I have been in and with the types of...

I will add my $0.02 backing up what osiyo said above that most of the actuator failures I have ever come across were due to excessive cycling and hunting which is a controls programming issue as...

Just to give a more serious answer to the question since I haven't answered it 100 times like the others. ;)

Essentially, it is like comparing any other software. They both do the same things in...

The voice of experience... yeah I just talked with one of the guys here and he said 1 out of 5 installations the comm is good as is.

Majority of the problems are due to STARing of the comm lines...

I have a feeling in the past the existing comm lines haven't been too problematic in that they aren't long runs and only have 10-30 controllers at max in the whole site.

...and yes it merely makes...

I was always happy with just automating what I was already doing which was using Excel for points lists and BOMs then using Visio for the drawings/schematics.

Kyle in the following video did some...

You are correct, this retrofit panel does not communicate with the individual novar unit controllers. The typical situation is to change out those controllers as well to KMC BACnet controllers and...

Sorry, I am so new (1 week) I still catch myself saying/typing THEY instead of WE. ;)

NexRev's business model is to cater to national chain stores and companies with multiple locations in many...

No they don't sell parts... YET! There is already a sign that says "NexRev Supply", but it's an empty showroom at the moment.

The daughter board you are talking about is actually a NexRev...

Yeah I just threw that in there since there were posts at the beginning joking about just slapping on the labels.

But as far as NexRev being a contractor locking you in... from the website:...

Here is a photo of NexRev's Freedom System which uses a JACE/JENE... I just began working with NexRev so I am not the most knowledgeable on the Tridium Line, but obviously it is possible to relabel...

I had high hopes for my site, but seems only I was interested in creating content and well it didn't take long for it to feel like a second job. ;)

That works out to about $15.38/hr with a 40 hour work week, which is pretty good for ANY job when you have no prior experience doing it.

The scary thing is... you are saying you put control guys...

Just an update to this thread... I have started writing a downloadable guide to those looking to get a job in the Building Automation or HVAC Controls industry. The working title is "THE Building...

Just curious why did the contractor walk away? Delta Controls is very particular about their Partners and usually there are a limited number in each state. most partners do a good job of following...

You know... I am glad I posted this question here. I am new at the company I am working at now and to be honest, I am much further away from being 'on-site' and in the thick of things talking to the...

Yup, true enough. Was being a bit exaggerated there. ;)

The acceptable range I think went up to 80°F which as an upper limit is pretty low compared to typical chillers. But the best efficiency was...

Sorry to be absent from responding with al this good info... I definitely took note of it all even if I don't completely understand it fully and will use it to ask more questions of the mechanical...

Yeah same even in the southern states there are actually cool days during that 1 week of Spring and Fall each year. LOL

So back to your original question... ofcourse it is possible, but you will...

Came across one of those newer McQuays that have the magnetic bearing that float the impeller shaft... they like 65°F all day long.

Which is crap... when the chiller is installed in Texas. How the...

Not sure exactly what it is... Here is what I have on some Wiring Schematics. I will look again at the full Mechanical Submittal tomorrow.

Yeah... odd that the DDC Controls would be controlling this on a large roof top instead of some sort of unit controls or simple pressure switches on the refrigerant lines... But Here I am.

So... I...

The expectation is that one filter might get 'more dirty' faster than the other. Therefore you would want to know when they individually need replacing.

The two filters you speak of, I am willing...

Yup sure did... I am now way up North in Ohio... Columbus.

What?! are you saying that every unit doesn't have the paper sticker schematics on the inside doors/panels glistening all shiny and white??? HUSH YOUR MOUTH!

:whistle:

Ok, I am a controls guy and not a mechanical service tech with guages and all... so maybe I am missing something.

BUT

Why would you not just take alligator clips or something and jump out the...

Here's some things that might be helpful...


A model number of the unit.
A cell phone pic of the sensor.
Any numbers or markings on the sensor itself.

The Internet and YouTube have been my source of education for many years. I am self taught on everything I know about Computers, IT/Networking, IS/Databases, Web programming etc.

But I am the type...

A-silly-scope?! Oh yeah I hang one of those off my hammer holding ring. :bhave:

I have never seen any controls guy ever have one of these, though I have seen some IT guys have one of those fancy...

Delta Partners are not in the business of selling Software Keys to individuals. Otherwise you would buy one and then start using it to program your own systems.

If you are some kind of developer...
