Weve had the digital varistream a while now and its been fine but lately whilst working the flow stops and it flashes "U" and will not come back on till you have turned the unit back on and off...i know about holding - and + together and adjusting i just cant seem to get it to work properly on any setting

What does "U" mean? What are we doing wrong? Thanks

but cant delete the thread 

Looks like low voltage shut off. Weird tho as it runs off van battery and van never fails to start

You can turn the U feature off. Open it up and re position or remove
Jumper inside. They don't recommened it tho.

They are gash though. Rubbish controller.

Yeh i dont like it to be fair, not enough control, its either dribbling out or flying out. No real control and these problems with letters popping up are stupid!

Im more than happy with my liquid logic analogue controller. So simple and works a treat.
