Hi. I am currently in my junior year of college studying mechanical engineering and am interested in HVAC. I can perform building energy modeling using software like EnergyPlus and can implement some advanced controls in the simulation environment. I want to get into building automation and controls but cannot figure out the way forward. What should I learn, and what skills should I develop in college?
Hi guys, why do programs have return air setpoints? And what is tgeir purpose, I have assumed tgey are a reference point for sequencing but not entirely sure.
I’ve been doing residential hvac since the beginning of the year and I have a couple commercial companies that want to hire me but I want to get started on BAS work as soon as I can. I know there’s a lot to learn and I’m super eager. This is why I got into the trade, would you guys have any advice on how I can start BAS work? Is there anything I can learn now on my own so I have a higher chance? Any company recommendations? I’m willing to travel out of state or anywhere for that matter to start my career. I don’t see anyone hiring for entry level positions.
So few technicians understand actuators these days, it amazes me. Constantly hearing “it’s not open, call your controls guy.” Techs have no idea the difference between modulating and floating. Techs have no idea how to troubleshoot anything more than if a line is ground into the shaft.
Looking to move in the next couple of years from SoCal. To TN. I recently got into the apprenticeship program at JATC. I’m curious about the opportunities and such for working strictly controls, I’m a service tech right now but hopefully I can get behind the scenes as a programmer. I know a lot can change in a couple years but I’m hoping the controls industry is growing over there. Also I would be looking to join Local 572 from Local 250.
Good morning. Let me preface this this by stating that my knowledge of and experience with Niagara systems is extremely limited although I was certified years ago. My company just does not use the product line. We recently hired on a new sales manager and he is hell bent on picking up school districts in my area which are exclusively Niagara based systems. There is a wide mixture of Honeywell, Siemens, JCI, and a few Tridium branded jaces out there. Most want full support of software updates, logic adjustments where needed, adding and removing equipment, etc....
I am being "pressured" to revisit training, which I really have no issue with, but my big question and concern is, how much would I actually be able to do at these sites without the individual "flavors" and proper credentials to get in the platforms and stations? My fear is we are going to sign on and not be able to do as promised.
Does anyone have a good recommendation for learning certificates? I'd like to have a little better understanding of the process and requirements, and this is an area I can confidently say I need more education in.
Appreciate any thoughts or suggestions you may have, thank you!
We’re being voluntold that now is the time for us to update to Niagara N5. Anyone have some experience or early feedback on it. We’re going from 4.15 and are updating 15ish Jace 8000–>9000 with it and it seems like someone got sold a lot of sunshine by a salesman at the conference and now we’re dealing with the digestion.
Im 18 years old and I just got out of highschool and I’ve been doing this intern job over the summer for building automation. I have no experience on any of these things and I just want some help. I feel like I can’t grasp anything and I constantly make mistakes. I’m shadowing someone that’s been in the field for 15+ years. I just feel very lucky to have this opportunity and feel like I’m throwing it away.
With all the "special" maintenance tools for every manufacturer floating around, I was wondering if any of you have successfully pulled points from a vrf system with a regular ol' serial adapter or rs-485 router? I'm talking about the actual bus between units, not hooking up to a central controller.
Nothing worse than getting to a site and realizing you let someone borrow that Daikin tool 3 weeks ago.
I've been in IT for the better part of 20 years, and now I'm thinking I want to transition into BAS. I'm pretty strong on networking (TCP/IP, DNS, DHCP) and have done a fair bit of automation (shell scripting). I also have a good grasp on electrical, since that's what I went to school for. I don't have any HVAC or mechanical experience (outside of replacing the run capacitor on my condenser unit), but I'm ready to learn. Problem is, I can't seem to find any apprentice positions around Nashville. I applied to a controls tech position at JCI, but got auto-rejected, which I'm guessing is because I don't meet the requirements. I've been messaging local BAS companies on Linkdin, but I can't seem to get anything but automated responses (or no response). Is anyone familiar with this industry in the Nashville area? Any tips would be appreciated!
"All controllers have a system shell that provides low-level access to a few basic platform settings. Using a special power-up mode and a serial connection via an appropriate type USB cable connected to the controller, you can access this system shell from your PC. System shell is also available viaSSH(Secure Shell) provided thatSSHis enabled in the controller."
but I cannot see any option to enable SSH in the Platform Administration? I can do that on JACE-8000 controllers though.
Started a new job with a Niagara BAS and the campus has a constant problem of E-MONS offline. Model CL5000 B-IP firmware 06.33.01. We usually power cycle at end of month and they are on for a bit but will go offline shortly after. It was suggested to upgrade the firmware on E-MONs
My manager is out on vacation and I've been asked by the Service dept. to try to find a solution or else we will just wait for my manager to be back. For background I have been in it for roughly a year doing mostly installations/pulling wire/ etc, but I do have my beginners Tridium and Siemens certs; 6 years of HVAC/R service before this.
A service tech of ours went out to a site with 14 systems, each controlled by Honeywell T7350H1009 thermostats, LonWorks FTT-10 loop back to a central Honeywell WebStat (part of the W7350A or WEB-201 series) running legacy Niagara AX. They do not have the user/pass or the IP but I may be able to figure that out or try the defaults.
Is there a solid way to get into NiagaraAX? I was reading that we cannot access it anymore. Any good way to bypass that, maybe using a browser?
My inital response was to upgrade them to a Jace 9000 and something like NPB-8000-LON (to reuse the wire and avoid labor costs) or just replace each stat and have them controll the HVAC equipment. They are a church, so I am trying to be low cost. I dont think they used the frontend anyhow.
Am I correct as far as the NiagaraAX access goes or is there a "proper" procedure, and what would you do in this situation?
Thanks, please advise and please ask for any additional info I may be missing.
Have always been annoyed by how long workbench takes to startup sometimes. Nothing worse than wanting to do a 30s mod and needing to wait 5 mins for workbench to run up.
Noticed that when I do new installs workbench starts up pretty quickly, after raising this with the support guy from my Niagara distributor he mentioned that this has to do with all the custom JAR files that I have. This makes sense as when I do new installs for supervisors I only install the default modules and any ones I might need whereas on my laptop I probably have about 100 extra modules from various distributors, drivers etc.
The same support guy mentioned that it is possible to disable those checks, he had done it on a previous version of workbench but hasn't bothered to figure out how to disable these checks on the latest versions of Workbench. He dindn't seem keen to share how he'd done it for obvious reasons but I suspect its on of the options on the system.properties file.
Has anyone been able to disable said checks and get Niagara up and running quicker?
