Who here uses one, and have you been having problems with it as mine kept flashing "U" and it had been doing my head in so I phoned them today and had a very helpful chat with one of the main guys from there (45 mins to be exact) and my settings where set wrong it seems, but I know others have had problems but want too see if your settings are correct but still having problems.
How many varistreams are you running,
1 or 2 batterys for 2 man set up.
Distance of varistream too battery/pump
I've now changed my settings to 3 on the controller and pushing the + and - together till flashes and going too "c"
This seemed too allow me too work the rest of the day today after battling with the "u" problem today so going too charge up tonight and hope to have a better result tomorrow.
Also ordered a split relay from them too.
