1. Proportion(P) zone
- Set proportional band. If the proportional band is larger, control output becomes smaller for the
offset and thus the setting value is reached later. If the proportional band is smaller, control output
becomes larger for the offset and thus the setting value is reached quicker but there might
be hunting if it is too quick.
2. Integral(I) time
- Set integral time. There can be offset only with proportional control. Integral is used to reduce the
offset. If the integral time is too long, it is changed too late but if it is too short, there might be
frequent hunting.
3. Derivative(D) time
- Set derivative time. To compensate for sharp temperature change, control output is proportional to
the angle of temperature change. If derivative time is longer, compensation becomes stronger.
4. Upper limit of output (O/H)
- Set upper limit of output range.
5. Lower limit of output (O/L)
- Set lower limit of output range.
