After a quick look, I have only one nit to pick
(and it is of course a matter of taste):

You wrote:

when V > 0 andalso V < 6 ->

I would write it like:

when 0 < V, V < 6 ->

First, by putting the variable V in the middle it
easier to see that the guard is a range test
and not any two unrelated conditions. Second,
I never use 'andalso' when a simple ',' would do.
