Morning have got a varistream control box it has black and red wires to battery and orange and grey I assume (my mum said you should never assume anything!) is grey wire to the black wire of the pump and orange to red wire? Thanks Ian

all the wires on mine where all red and black, but if you look where the wires come out of the varistream it should have the + - signs

My one is also marked up, i.e red and black pair from plastic circles says pump and other marked bettery.

not a varistream then unless they have changed wiring in the last couple of months. Williamsons always put wiring and adjustment instructions in with their systems. Is it a variflow?

[ian1965]

yes it is got it in June!

Sorry. I see the Variflow has the same colour wires you described.

Our Varistreams have the wires labeled on the Varistream box
