
Cooking condition, depending on the occurrence of smoke
together with rise of temperature, i.e. level 3 = 2S+deltaT >
10. NOTE! S has to be > 2.5 and deltaT has to be > 3.

Clean condition, the most sensitive condition requiring very
clean and stable environment, i.e. the values for all the other
conditions (level 1, 2 and 3) must not be exceeded.

In a learning period there are twenty 36h-periods (i.e. 20 x 36h =
720h = 30 days = one month).
During each 36h - period it is recorded if level 1 is exceeded at least
one time. If so, the 36h - period will get a check-mark (see example).
If three or more of the 36h - periods during the learning period have a
check-mark, the Steam / tobacco condition will be adapted. In the
example this happens in the
36h-period no. 10 (i.e. after 10 x 36h =
360h).
After the 36h period no. 20, the next learning period starts again in
the 36h period no. 1. The check-marks are inherited from the
previous learning period . Depending on if level 1 is exceeded during
the 36h period respectively or not, there will be a check-mark or no
check-mark.

In the example, the Steam / tobacco condition will be ended after the
36h period no. 3, since there are left only two 36h periods with
check-marks in the learning period now. (If later, one or more 36h
periods will get a check-mark, the Steam / tobacco condition will be
adapted again as long as three or more of the 36h - periods during the
learning period have a check-mark.)
