This goes out to all of you who service controls for a large school district.
What are your responsibilities?
In our district we handle incoming calls from our HVAC techs but we also are...
Ok, its been awhile and I forgot.
So please remind me.
When testing the low/high ports on a vav, should you read the available duct static pressure from the AHU if the damper is full open? Using...
I know about the new launcher and in the near future our NAE/JCI folks will do just that.
But I'm still faced with all the FX JACEs and AX JACEs.
From experimentation, all of...
I haven't seen anyone post this yet, but I'll bet there are many out there with a similar problem.
I work for a large school district which carries many different control systems.
Liberal vs. Conservative.
Talk about fear mongering! Thanks Limbaugh and his cronies. Liberal simply means to be open-minded, conservative is to be cautious...
How about using your mind and...
My brain and laptop computer.... after that klein 11-1, headlamp, meter and needlenose or strippers.
I will always advise to take advantage of knowledge when it's offered to you. I teach final year electrical apprenticeship for a non union apprenticeship program. I've been in the HVAC controls...
I love not going to the same place doing the same damn thing day after day. It truly cracks me up that they tell kids in school to work hard, get into college and get a career. After they spend 4...
Shouldn't any MAU unit have preheat coils to prevent the freeze stat from tripping all the time?
If it doesn't, does a logical solution entail programming the hotwater coil to circulate with the...
So we have CCT and PCT. I know, I know, don't have them on the same desktop.

Thanks for the response!
Yep, its both age and low bid.... can't seem to get it across to the Project Managers, etc how important it would be to spec one manufacturer. I think we are slowly getting...
Anyone else finding that they need a different dongle for PCT and FEC?
PCT dongle is a FX-BTCVT and an FEC is a MS-BTCVT.
Man, can't JCI just have one?
Hey out there!
I'd like to see if there are any other Controls guys out there in a similar circumstance...
I work for a school district that maintains 162 schools with more being built.
I would strongly advise you to do some work on the install side first. This comes from personal experience. I installed for 7 years as a journeyman electrician before I got the laptop and learned...
Uploaded the DX program into my GX9100 tool and traced back to the PID loop from the AO. I doubled the value on the PB on the data 2 page.
Works like a champ! No more chasing, it's a mellow, nice...
I need to reset a cooling valve loop on an air handler controlled by a DX-9100.
I see the control percentage change from 0 to 100% constantly after we had a clogged pipe problem...
Like CrazziFuzzy, I'm a maintenance guy,
I started out as an installer/journeyman electirican, got into controls about 10 years ago. Turned into a tech when the company I was working for asked me...

I spent the day behind one today. Now ready to get back to plugging...
Just wondering how many out there are on the service side of controls?
What's your background? Did you do the programming side first and service later?, etc.
So I found some loose duct lining in front of the baffles in the Supply Air section. This looks like it came from the fire alarm guys installing a duct probe across the section. I reached in with a...
Thanks for all the replies!
- ASC means application specific controller in JCI language and I'm referring to the AHU controller, not the VFD. If you haven't worked on JCI's metasys line before,...
Ok, so here it is...
AHU unit controlled by JCI AHU controller. (Metasys)
- The supply fan vfd is suppose to be controlled by duct static pressure at 1" w.c. for setpoint. I find the static...
I looked up FAN 410 in the CG Products search that is for JCI.
It just has 2 hits that mention enumerated sets.
I never installed JCI stuff. But did do a lot of Siemens, Invensys, etc. As far...
Did you check out the Johnson Controls Website?
Look under Metasys or look under scheduled classes. We just had one were the teacher traveled to our location. It was on FX series of controls and a...
