    Trane RTHB - Chiller High Level Interface (HLI) comms to BMS

    Hi Trane experts,

    I have an RTHB, is there any new products / modules being used to read the chiller data - (like via COMM4), or is it still the same old COMMS module?


    Thanks.

    Does the chiller have a comm 4 module installed already??if so you maybe able to install a pic module which will talk modus as I have done this on a RTHC previously.

    Or I have been told that Niagara have a comm 4 HLI module,not sure on what is involved though as I have not been installed 1 yet

    PIC controller is not compatible with RTHB.
    Upgrade UCPII to adaptiview with UC800 to communicate via MODBUS or BACnet
