I have gone through all the settings again this morning on one of the pumps.
I have got the external setting at 12 o'clock and the internal on (a)
the result of this is that when I disconnect the pole the motor is slowing down and after about 30 seconds it goes off then 2 seconds later kicks in again
(all very slowly) and keeps repeating itself
So my question now is :-
once you unplug should the varistream shut the pump down immediately or is there a delay??
If there is supposed to be a delay in it shutting down the pump then its probably me being an impatient twat.
If there should not be a delay then I am getting warmer

but not there yet
