The Omnifi DMP1 includes a thermal sensor to detect current ambient
temperature.  The owners manual states the "allowed" operating range
is 14F-140F.  For those of us that live in "Extreme" climates such as
the Arizona or Minnesota, it can suck to see "Temperature out of range"
on your Omnifi Controller.

The temperature controller is at "U4" on the DMP1 hard drive board.
To bypass the parameters, simply jumper pins 1 $ 4 of this circuit
together.  I used a short piece of fairly small diameter wire I had
laying around.
