MIT sets the minimum time between
successive position commands being
actioned. It is used in situations to
reduce the number of starts per hour
and to smooth out fluctuations if
continuous positioning is implemented.
Setting the longest possible time while
maintaining acceptable control will
maximise the life of the motorised
valve.
