MiniDEC Operation
The MiniDEC controller monitors current going to the light fixture inside the Twister enclosure, and also heat inside
the enclosure. When it detects that the light is on and/or the internal temperature is getting warm, MiniDEC runs
the enclosure fan. For best results, enclosures must be connected to live power at all times.
MiniDEC Operation is completely automatic.
