    Default Hometronic FW upgrade

    I have a fairly old HCM200d UK with FW version 7.10, is there a newer version and how would one go about updating it?

    Thanks,
    Slavo

    I don't think Honeywell actually allowed firmware upgrades on any of their heating systems.

    It does have a serial com port on the front under the perspex cover. I think I might even have the cable for it that I got with it.
