Are you like from the Moon, or something like that?
You gotta be kidding, right?
If vav boxes are part of CCP they do know what unit is doing without DAT sensor in the box.
Black Book contains same information as IOM, they just put several IOMs and some field collected troubleshooting tips in one book. They want something like 40 bucks for it. Guess what I paid same...
I did few of this and to the best of my recollection most of the problems were on JCI ability to apply some drivers to be able to talk BACnet. My understanding JCI has 3 party integrator writing code...
Agreed, it has nothing to do with BCU, BCU just delivering set up information from the units.
What about getting the contract, subbing out controls to Trane, getting local office OK to go to school and after contract will be up for renewal hopefully you'd be in a lot better position to get it.
FYI Engenuity is not selling high end controllers, mostly programable to anyone, only to qulified customers.
The best bet will be to add LON card to the chillers and go LON to Modbus - I never did it but i'am sure it can be done, another solutuin is to get BCU, and then go BACnet to MODbus with Fieldserver...
I see it as attempt to be able to restrict the product only to qulified individuals - in their mind. So they are trying in future to sell the product only whom they decided to. And it is not about...
clean condensor you remind me of the wise custodian from another teen movie! It is not as cut and dry most of the time. At this point of time you'd better be dead if you are not busy. There is no...
don't waste your time bring power wash on the roof spread the coils and wash it up!
[QUOTE=dapper;1591568]Where did you hear that Bob? That's not one that I have heard before and it seems to be very improbable since there are so many different LON manufacturers and outlets for...
I've heard that LONmark started the certification program for techs and integrators, now pretty soon in order to work with LON you will need certification. Welcome to the proprietory world!
If you are computer tech for you is step back. In the same time you are not going to be control tech - no expirience. You should consider it like an offer to do DOS operating system technical support...
Before trying to unassign and reassign, you will need to connect with Rover, or N-Util or lonmaker and make sure all the devices are on the link, and if they are and your link is OK - then you can do...
Welcome to the Big Blue World - Indy Blue is one of your colleagues
Min VAV setting is not to provide heating or cooling in the space. It takes place when the space does not need any cooling or heating, but other spaces do. In this case in order to maintain adequte...
i've seen a lot of people who can do some of this tasks, and not work for trane, don't forget we started with VAV box - there is no need to call to trane to trobleshoot the vav box. May be the guy...
Unfortunately for the customer They can be Siemens, JCI, HW, Alerton and so on. All companies work for profit and even a little guy does not work for free and if given chance to secure customer base...
You are right on the money, Carnak! Gas laws are working only for superheated gases, like nitrogen in HVAC application. If you have mixture of gas and liquid like refrigerant you will need to follow...
The VAV box is receiving cool0-heat command ether from front end or from DAS which as you noticed is wired to auxilary input - if there is no front end problem most likely with the sensor if there is...
What is the size of CK5BXN060021AAAA, i think it is Carrier
Thanks Kevin, no we threw away condensing unit about 6 month ago and i could not find original qoute - I was not sure was it 4 or 5 tons so AHU is still there - I've got numbers from it and it looks...
Thanks
Lennox AHU CB518-65-1P, what is the tonnage of the coil?
Try to crimple fuse holders to make better contact - helped me.
You did changed filter dryer when you changed TXV?
It looks like in this case the problem are solenoid wiring, It is sort of stupid that the solenoids are controlled by building controls, it can be done though if they would have removed all time...
Ip
In this case I would just pickup switch from Graingers and install it on the control side of Fan. You are staring and stopping the fan? If you are as i told forget about the starter and install...
You should be able to navigate through the system with the manual, it is not the best and easiest set-up, but in my experience controls were set up as having more safeties then the unit actuallly...
You don't actually calibrating it with hands you just enable point through schedule every night and the system is calibrating itself.
There is an installation manual with retofit kits, you will need set this boxes as generic, mesure the flow for 0% 50% and 100% damper opening - and set up the size of the box. also it is good idea...
Check if the units have HGBV on stage 1, also being 90% OA it is very important how they are controlled - it should be combination of DA and space temp control but in any case 90% OA unit shoul not...
try 1111
To the best of my knowledge this rumor is about year and a half old.
And I'am sorry, but you people like you will be the first JCI will wipe their corporate ass first when the time will come.
JCI probably would also own your mail room and if you let them your custodian department, the next thing they will bring the crew of supervisors and schedulers, occupy half of your building and will...
Keeping OA damper at 0% also depends from what local codes will allow you to do, besides ASHRAE, also in kitchen areas CO2 usially not an issue because you have exhaust hoods and makeup air unirs, in...
There is no such thing as Trane Tracer Chiller, there is trane chiller which can be talking proprietory or LON, or trane tracer which is talking BACnet.
Click on help menu, there are 3 points you'll need to check( to the best of my memory) something about FIFO buffers, and keep in mind polarity.
I did not question the actual matter - but some of the pics look like they were taken with unit running and slight frost is developing - I don't have opinion on the problem - my point is the pics are...
This is stupid even to show the pics of the unit with open evap section being frozen up - what they suppose to prove - when you open evap section door and bypass the flow away from evap coils - evap...
You need to google fan curve it will help you a lot
Jogas I see your pain. unfortunately this set up does not seems to be cut and dry, something missing, if you want email to me phone number of the site and rcf and tgp files i'll try to see what is...
There is no sequence of operation for CV Voyager with VAV boxes usiallly it is fileld programmed in tracer-summit, if there few VAV boxes 12- at most 15 i am running routine to calculate the number...
I don't think tracer will have option for calibrating modulating hot water valve, but what you can do is: to change modulating heat option to staged hot water option in ucm editor, changed the wiring...
My guess - it was some kind of CCP retrofit, which did not work too good.
You will need to find why the unit is failing in heat - now it sounds like mechenical problem, also you will need to find...
