Gav86 this is the Bianca prior to the one just released. To upgrade it would need the new LCC or LCC firmware as well as additional hardware, and wiring for said hardware.
The main thing the V3 Bianca gives is high and low flow programmed times (hence the additional hardware)….to use in conjunction with the lever. Of course there’s more hardware to potentially have problems and this still produces a superb shot. I wouldn’t think it’s necessary to worry about it considering the excellent price for an almost new machine. Plus this version is tried and tested.
