controlled by the average air
temperature. If the set-point is 55

°

F

with the differential 4F, the cooling
unit turns on at 59

°

F of air

temperature (It may be higher than
59

°

temperature is 57

°

F, and then the

wine temperature is around 57+/-
0.5

change so quickly that it maintains

temperature that would prevent wine
bottle temperature from fluctuating.
