2.Temperature | a. | Air sensor |
| When using | an air | sensor, the | wine | |
fluctuating |
|
|
| bottle temperature is mainly controlled | ||||
|
|
|
| by the average air temperature. If the | ||||
|
|
|
| |||||
|
|
|
| the cooling unit turns on at 59°F of air | ||||
|
|
|
| temperature and turns off at 55°F of air | ||||
|
|
|
| temperature. | The | average | air | |
|
|
|
| temperature is 57°F, and then the wine | ||||
|
|
|
| temperature is around | ||||
|
|
|
| air is light enough to change so quickly | ||||
|
|
|
| that it maintains relatively constant | ||||
|
|
|
| average temperature that would prevent | ||||
|
|
|
| wine bottle temperature from varying. | ||||
3.Temperature | a. | Displaying 55°F, air sensor | a. | Move the air sensor away from the | ||||
