Actually the JSON looks like this  ```json  "C": {"isNative": True, "values": [16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]},  "F": {"isNative": False, "values": [61, 63, 64, 66, 68, 70, 72, 73, 75, 77, 79, 81, 82, 84, 86]}}  ```  So not all whole-F values are accepted.  I'll add a fix to make sure correct F temperature is set.    As for min and max - it would be safest to stick to the provided list. What is the advantage of converting?
