I have been fighting a VAV replacement problem on and off for over a year now. Obviously the particular VAV is not in a critical location at our plant but the implications are that if I do suffer a critical failure I am in no position to respond. We had a VAV box controller fail in its ability to communicate with its remote temperature sensor. The VAV in question is a W7751E1007 serial number 010017C4FE00 and it was being handled with CARE/Excel10 version 1.5.2b software. I replaced the unit with a W7751F 2003 serial number 041ABCFA0100. Using CARE on our Laptop via a SLTA adapter I tried to commission the new VAV Box controller as the one just removed. I received an error message (Controller already in use). After a great deal of troubleshooting and trial and error I have deduced that the Controller in question is the new one just installed. I can commission it as a E-Link Zone Manager for some reason with out getting a controller already in use error but I cannot commission it as a VAV. I now know that I cannot commission it as any VAV, not just the position of interest. I experimented with my other VAVs and found that all of them that start with serial number 01 can be moved around and commissioned pretty much at will. The two controllers I have that serial number starts in 04 cannot be used in my configuration.
I purchased a copy of e-vision a while back to try and use it to commission these devices but our system has not been set up with an e-vision project and I havent gotten anywhere down that road.
Has anyone seen this before? Is there a paddle out there, for me?
