    I have a building that has a Barber Coleman network 8000 controllering their equipment. I know that Invenysis is now Barber Coleman but what I am looking for is any info on this system so I can determine how the heating and cooling setpoints are configured for 2 air handlers with 30 dump boxes. The network 8000 is the one with the key pad on it and I do have a password to get in,but I don't know how far I get in. The system has perimeter hot water heating and uses the 2 air handlers for a/c and hot water coils for tempering fresh air. Any help or info would be appreciated. The dealer here in town is the only one around and is very hush hush.

    The controller with the KEYPAD is a GCM , networked to theMZII's ( MZII's do not have keypads ).

    You may have an access code / password but depending on what level access was assigned you might not be able to do anything other than view current status.

    Your right Control Man, I've got level 6 only out of 14 I guess. The main controller is a GCM-84211-1-0-1 and the software version is 5.3A. There is 2 microzones MZ2A-105-0-1-1 and 2 Siebe micronet integrators to ASD bus MN-ASD1. Any info on how to walk through these would be appreciated. There is a 25pin hook up for a laptop but I would imagine that the dispaly is good enough. Is there a master code that I could get a hold of to give me higher access? My email address is XXXXXX if anybody has any info that could be useful. Thanks ahead of time for any help.

    The DISPLAY will only show what is in the GCM , you need PSI software to access the MZII's

    Depending on how or who did the programming things can vary.

    Many use the MZII's as dumb devices , do the programming in the GCM and pass the info over to the MZII's other do the programming in the MZII's and use the GCM for common programming /networking this was the way it was suppose to be used as a STAND ALONE if GCM failed.

    The CABLE is used for hooking into LAPTOP / PSI or for HOST ( older system ) SIGNAL graphical frontend.

    So Control man what you are saying is that I can't help the customer because the control company is married to them aka I'm screwed. Thanks for your help anyways. Next time I guess in the installation the customer should ask for the passwords, training, software, and manuals in the deal.

    Customer is ENTITLED to all of that , they PAID for the SYSTEM all that it includes not just the USE OF IT.

    There is too much of this "IT IS OUR SYSTEM " mentality by the control companies / reps the customer owns it not the contractor.

    They should have recieved a full set of MANUALS , a complete copy of the ORIGINAL PROGRAM , Training along with HI LEVEL ACCESS for their own use.

    Things are just going to get worse for INVENSYS in Ontario after a recent purchase by DIRECT ENERGY , if you take INVENSYS way of doing things and add DIRECTS hollyier than god attitude.

    As for your customer they should be able to get everything they are entitled to.

    There are contractors who work on NETWORK 8000 that are available to do service / programming and work with the customer and HVAC contractors, we are just hard to find.

    I don't know about holier than god but we try! We bought the Invensys dealer in T.O but we can't sell the stuff in my area because of the London dealer who is giving Invensys a horrible name. There is a huge problem with controls companies not providing the software and the training to the customers. The last job we quoted,(and lost to invensys dealer) called for 30 hours of training for the on site guys by the installers. The engineers have to be very specific in the spec for these jobs and then there will be less problems. You are right our controls department has some issues.

    SHip: what exactly is the problem you are having? The heating/ cooling setpoints on an ahu can vary. The setpoint can be reset by demand, oa temp, warmup, etc. This is probably programmed in the MZ not usually in the GCM. Usually I am in the MZ and see a value being sent from the GCM, may be difficult to work backwards and see numbers going from the GCM to the MZ. You can get a password for a single day by calling Invensys.

    You should have ZONE2 blocks in your GCM for each MZII you can see what is being sent from the GCM to the MZII.

    In the MZII you should have EMS:1: for point value passing as well as WINDO: : for viewing info from the GCM
