3-8v for Tunze, Where did that figure come from?

[Harry_Fish]

Where did the 3-8v figure for the tunze pumps come from?

Is that the correct vlue from Tunze?

Or was it from a test or trial & error?

Thank you

It was developed for the best operation for the Tunze pumps.

3=0 and 8=100% ????

Not as such, it stops the pump going to 0% and 100% so you dont get motor bounce
