Iím not familiar with that one at all, however Iíd bet itís not a cold plate as I donít think those are common in new builds as OEM.
If itís not, then all you should need is another thermostat.
I just converted my spill over to a thermostat / fan controlled fridge temp.
Iím exceedingly happy with this as a thermostat, itís extremely adjustable, and very, very accurate. I checked it against my Fluke and itís within about .1f or so of actual.
It would also work
as both a fridge or freezer so you wouldnít lose anything
