    I do not think that I have a driver board on this unit. The micro processor controls the exv directly. But just in case I am misinformed, what are you calling the driver board?? and where is the fuse??? It would be great if it was just a fuse.

    Presently, I have 3 possible culprits:

    1. The board or software that controls the exv
    2. The exv or maybe the wrong exv
    3. The wiring to the exv, --the cable

    Of coarse, still could be the thermistors, but I haven't seen that. Some are new.

    I think that the driver boards came with Flowtronic II, this unit is Flowtronic I. Any input on this assumption??

    You should have it now. I sent the program to ultimatehvac.com. Hopefully he will be able to post in on the internet so I can link it in this post. I am no computer guru, but I think that it would be helpful since several people have indicated an interest in the program. Perhaps some that have actually used it can give some more detailed instructions on hooking it up. If the program works as I have been told, it will be very helpful and save a bunch of time.

    to the best of my knowledge you do have to use the older windows version for alot of carrier stuff, i believe it has to do with com port settings and conflicts.

    hooking it up is no problem, just use the designated connection and three wires out of a standard phone cable, rj-11. i dont remember the exact connection points / colors. i will look into it i think i might be able to find it, besides that i thought it was mentioned in the o&m

    OK hvac-alan,

    First contact Telebyte @ 800-835-3298. Order a M/N 65A or you can go to their website ( http://www.telebyteusa.com ) and order it. It is an external powered Ground Loop Converter. Power it up per the directions in the box.

    When you start Flotronic Manager, on the first page on the right side it tells you how to connect. You're going to connect from plug J8 on the Flotronic to the Telebyte 4-20 GLC so follow that connection diagram. Connect two wires to your 6 pin plug at pin number 3 and 6 then connect the other end to your GLC at C+ and C-. Don't worry, everything is labeled. It sounds harder than it really is.

    Once you get wired, just plug in your 6 pin connector onto plug J8 on the board and plug your GLC into your laptop. I use a 25 X 9 pin converter then a gender bender to get to my serial port.

    Fill in M/N and S/N and your name for operator ID then make sure all your configurations are correct then press Enter. If you are communication correctly, the cursor will rotate every few seconds.

    It shows Entering Water Temp, Leaving Water Temp, Leaving Water Setpoint, Cir A and B Ret Gas Tmp, Sat Sct Tmp,Superheat, EXV Calibration, EXV actual Position, Sat Cond Tmp, Liq Line Sol, and if your oil pressure switch is made. It shows which compressors are running: A1 A2 A3 A4 B1 B2 B3 B4.It also shows which fans are running on Cir A and Cir B. It also shows any alarms. Like I said, its a great little program. You see exactly what the microprocessor is seeing.

    Good luck. Let me know if you have any other questions.

    That is great information. The above is the part that I am not clear on. I have a nine pin serial port adapter that I use for Comfortview. Can I use a phone cord to connect from this adapter to the Model 65A????? I suppose it may be clear once I get the converter, but wanted to ask while things were still fresh.

    760 step motor

    Earlier I stated that the EXV motor I needed was a 760 step motor. Now I am not so sure since I have found some Carrier literature that indicates that the motor has 1500 steps. Does anyone have some info on this??? Both EXV's have been replaced. Circuit B's exv has been replaced recently, then the motor fried and that was replaced last week. Want to verify that I have the correct step motor.

    The answer is NO. The Ground Loop Converter replaces the serial port adaptor that you use for Comfortview. And you cannot use a phone cord for Flotronic Manager. This is really OOOOOOOOOOOOOOld stuff.

    Like you said, once you get the GLC, you'll see. You plug the GLC into your serial port with the help of a few adaptors that I mentioned. Then you connect your two conductor wire to the C+ and C- terminals on the GLC. At the other end of your two conductor wire, you connect your red and black wires to pin number 3 and 6 on a 6 pin female recepticle that will plug onto the J8 plug on the microprocessor. I know you can get the 6 pin female plug from Carrier. I just found an empty plastic bag in my bag of cables with Carrier Pt # HY 06AM 017 Then it says "Terminal" under the part number so I think that part number is correct. Once you get the plug on the end you are ready.

    It goes like this: laptop serial port to the GLC. GLC to the two conductor wire. Two conductor wire to the six pin female plug. Six pin female plug plugs on to the plug J8 on the microprocessor.

    If you're anywhere around Houston, TX, it would be alot easier to show you than it is to try to explain it. It really is easier than it sounds if you have all the correct parts and pieces.

    Good luck and stay in touch.

    You have been a great help. You have filled in the part that I did not understand. I haven't been in commercial too long (1 year) and most of the guys in my department are far more advanced in chillers, but my niche is that I know a little more than they do about computers--i am looking forward to broadening their horizons a bit, like they have done for me. Accessing the board in this manner will be something that none of them have done.

    Thanks again. I am in North Carolina but if I can't figure it out I may have to come to Houston--but a suppose right now accomodations are alittle limited.

    Did you or any other tech from your company replace exv board?? do you have one exv board or one for each circuit??? if singular board switch circuit b and a and see if your exv operates properly that would tell you if you have a bad board... I would suggest replacing the sensors only cause that you and I saw the same sitution not saying your wrong... Please keep me inform with this chiller would love to get more information and help in any way possible... Are you base in Mass??? if not where??? just an fyi.
