Min/max limit positiv:
− Niedrigster Control output clg = Low limit + Min/max limit
− Niedrigster Control output htg = Low limit
Min/max limit negativ:
− Niedrigster Control output clg = Low limit
− Niedrigster Control output htg = Low limit - Min/max limit
Min/max limit positiv:
− Niedrigster Control output clg = High limit
− Niedrigster Control output htg = High limit - Min/max limit
Min/max limit negativ:
− Niedrigster Control output clg = High limit + Min/max limit
− Niedrigster Control output htg = High limit
High limit = 28
Low limit = 16
Min/max limit = -2
Cooling:
− Lowest control output clg = Low limit => 16.
− Lowest control output htg = Low limit - Min/max limit => 16 – 2 = 14.
Heating:
− Lowest control output htg = High limit + min/max limit => 28 – 2 = 30.
− Lowest control output htg = High limit => 28.

Function
− Amplification factor (KP).
Integral action time (Tn).
Adjusts high und Low limits to end position. En-
sures the difference between heating and cool-
ing output in the end position as well as needed.
