a set temperature is selected that is less than 5°C

above the actual temperature, this set value is reached

without identification. In this case the control parame-

ters are taken from the SRAM.

If these values are faulty, they are not accepted by the

Fuzzy control, and fault

occurs.

Select a set temperature that is more than

5°C

above the actual temperature. This causes the

Fuzzy control to carry out an identification in order

to determine new control parameters.
