After starting the program the heating is switched off and
control parameters are determined. Then the heating is acti-
vated to reach the start temperature of segment no.
1.
(5)
At the end of the segment the actual temperature is still
below the end temperature, when the program starts seg-
ment no.
4. A negative temperature gradient is available. As
long as the momentary set temperature is higher than the
actual temperature at the beginning of the segment the unit
heats until the two temperature curves intersect.
(6)
At this point the heating is inactivated. The temperature
decrease given in segment no.
4 is too fast for a circulator
without cooling aggregate. Thus the actual temperature
decrease is slower than the set temperature.
0 The times of segments no. 3 and no. 4 should be
extended so that the circulator can keep the given
values.
