The earlier models of the NETWORK 8000 are basically indestructable , I have MZIIs mounted in Nema 12 enclosures on the sides of RTU's with windchill of -48'F and they have not failed in over 11 years.
Programming is nice and easy and up until INVENSYS started screwing with everything the GRAPHICS were nice and easy as well.
Getting good REP is hard biggest complaint is poor service , job incomplete , too secretive and parts not available.
We have been using B/C's Network 8000 for over 12 years. Had very few problems with it. Microzones last forever and system is easy to use. We didnt like it, at first. but that was because our control company is not very good. We soon learned to verify all work done and ensure consistancy in programming/graphics. The frontend Ultivist program is running on OS2. Its kind of a antique.
Huron: What kind of VAVs? White Micronet or grey MicroFlo? Not much you can do to repair them, just replace. Is there a Global COntrol Module? If there is you can get inside there to overide things to check out the VAV.
I have the white micronet VAV contollers (MN-FLO3T). I am interested in purchasing the software to program the defaults for the controllers. The building I service has a Invensys BAS with Signal front end, integrators along dozens of VAV contollers and microzones. I do not get alot of cooperation from the local invensys dealer. Help would be appreciated. Have you had much experience with this system.I am located in southeast Michigan. Thanks for any help
If they have SIgnal then all the VAV info should be on the screen. What problems are you having? The Micronet controllers require a MN-CIM plug and the micronet program (probably aobut $500). They're really quite seperate from Invensys but can accept values from the GCM. You can access the GCM by clicking on any point in signal and then on the "terminal" box that comes up.
I am interested in the procedure for replacing a bad VAV controller. Do I need to program the controller's default at the controller with micronet software or can I do it through Signal's terminal mode. How about the Microzone II. I understand you need additional software to program them. I have a building with Trane Intellipaks, Invensys VAVs with hot water reheats controlled through Signal. Thanks for any help.
Micronets come with a program from the factory that is for multistage electric heat. If you've got floating valves then it will power the open and close at the same time because it thinks there is electric heat. DAmper rotation is also another consideration. The GCM is capable of sending network values although if it was not programmed to then the box will use it's own values, which could be WAY off. Microzones HAVE to have PSI to access. You're a couple thousand into it by now. I just got a quote from Mcquay for a program to look at unitvent controllers and they want $5000.
For the MZ11 controls you need a program called PSI personal system interface, there is an old version that ran on dos and W95 and there is a newer version compatible with all the new os's.The newer one is more expensive but is a much better tool and you can build it to add documentation (upload\download databases in the GCM,LNC,LCM,MZII,MICROFLOII & PEM Controllers.) You can also add the visio drawing tool to make logic prints from the databases you backup or start from scratch. The visio prints have real time monitoring capability. as for the Micronets they really are a seperate system that talk to their own integrator. Then it is the integrator that talks to the GCM (the terminal that you are talking to in VT100 when you go through the signal graphics program) you wont have much luck replacing a Micronet without access to the file configuration through the program called MNETCI it requires an adapter call a MN-CIM this adapter comes from the factory without a voltage supply and is expected to have voltage supplied to it by the port on your computer.Although we have run across laptops that they would not work on and there is a process of soldering in a battery pack to the cable to get it to work (Invensys instructions available for that). The cost of this program and the cable is about 500.00. The cost of PSI ( the original version is about 500.00 this program will need adapters (485-232 converter) also if you want to talk directly to the devices with a laptop.The newer version of PSi ( PSI for windows )list prices and build information can be found at http://www.STONETSYSTEMS.COM.
The STONENET Systems software has a few glitches in it , will lock the system up at times. Company the developed it is a off shoot of a INVENSYS dealer , their own service dept has problems with it on some jobs.
