Exactly my concern. 2 thoughts:
(1) The fridge must already be fitted with some kind of temperature controller to regulate the freezer and should be able to maintain a constant temperature there (right?). I was hoping the dampener or whatever you call the device that transfers cool air between the 2 chambers would be able to be controlled by the ranco sufficiently to maintain the temp in the second chamber. So in essence, I would have 2 chambers, 2 controllers, and 1 cooling source. Do I at least have a hypothetically sound plan?
(2) Would keeping the top compartment at 0 C (32 F) be cold enough to supply the fermentation chamber with cool air to counter the heat produced from rapid primary fermentation? It seems to me that a maxed out freezer compartment would be able to regulate the temp of the fermentation chamber better (but it could also over shoot).
