Barcrest All fired up (mpu5) hold button in demo mode

Hi everyone,

I've recently bought an all fired up machine and love it. I just wondered if there were some possibilities:

Can I disable the hold.vutton feature in demo mode?

Can I increase the ballance hold from 60?

I've found and gone through the mpu5 manual but can't find anything about this...

Thanks in advance!

Chris
