The pre-transfer charging current is controlled to an optimum value to suit the environment
(conditions identified based on data from the environment sensor).

0: enable fuzzy control. (default)
1: low humidity mode. (The pre-transfer charging current is
lower than the standard level.)
2: normal humidity mode.
3: high humidity mode. (The pre-transfer charging current is
higher than the standard level.)
Selecting '1' through '3' makes the mechanism independent of
the environment sensor.
