Lenco Trim Tab question

[Seefood Man]

Thanks for looking! On my new boat I have a pair of Lenco trim tabs that have a auto retract feature on it. It is wired into the tach and when I turn the key off it will take about five minutes for them to retract. Is there a timer setting on these that I can shorten the duration it takes to retract?
I would like them to retract as soon as I turn the key off. Any ideas?
Thanks in advance
Pete
