    Trane TD7 can not communicate with UC800

    Hi, I buy a used TD7 which used to connect to UC600. Now I am going to connect it to a UC800 in RTHD. When I power it up and connect it with a ethernet cable to the UC800, the screen show "Display Failed to Establish Communication". The UC800 loads RTHD version 6.00 software. Which parts I do wrong?

    Regards

    The Ethernet cable is not connected between the display and the UC800.
    • The UC800 is not powered.
    • The UC800 just has the backup application running as received from the vendor. Download the RTHD application software.
    • The UC800 has an invalid configuration. Download a valid configuration using the Tracer TU service tool. (I have meet it before. UC800 firmware is CTV.)

    I don't know exactly what is "Download a valid configuration". Is it OK to configurate the UC800 as new one?

    You need to clear the UC800 and upload a valid configuration for that specific chiller.

    I keep pressing the service button when power up the uc800, and Confirn the operation in tracer tu. After the controller has been reset, I open a CH530 configuration in TU And save it into UC800. But the TD7 keeps showing comunication error.

    Hmmm, so you are connecting to the UC800 via TU program?

    If you have TU, then you should be able to fully reset the UC800, then configure it as a RTHD. if you have it configured as a CTV, then it wont work.

    TD7 screens are for screw chillers, not CTV (Centravac)

    UC800 can be many things to many chillers But CTV no for RTHD.

    I clear the UC800 and set it to RTHD v6.0. Still not work.


    I connect my PC to TD7 via ethernet cable. In the Wireshark, I can see the TD7 having a static IP, 192.168.1.30, and looking for 192.168.1.4.


    While UC800 looking for a DHCP Server.

    The problem isn’t your UC800, it’s your display. You bought a display configured for a UC600, not UC800. I hope you didn’t screw up the settings in your UC800…

    So is there a way to update the TD7 software or re-configure the TD7 for UC800?

    Regards.

    What exactly are you trying to do? If you have a RTHD with a UC800 that means it already has a TD7 display.
    RTFM!!!
