VE.Bus on old Phoenix Multiplus family group 18, possible?

Hi,

I have an old Phoenix Multiplus 24/3000/70 with family group 18 according to the documentation. Microcontroller sticker says "1812144.HEX". Is there a way to upgrade the firmware to a newer version that supports VE.Bus? I know the microcontroller is not compatible with firmware version 4xxx and newer.

I have a MK3-USB.

No, there is no way to upgrade the family group number, this is limited by the hardware.

MK3-USB will only communicate with VE.Bus products (19,20 or 26,27). It will not work on VE.9bit products (18).
You'll need a MK2-USB to communicate with VE.9bit products.

Thanks for answering.

Do you know if the microcontroller is the limitation? In that case swapping it for a family group 19 microcontroller could do the trick if the rest of the hardware is identical.
