The limits IntMax and IntMin are only valid under external control (see 7.5.
Internal / external control). They restrict the temperature of the
internal bath to the desired maximum/minimum, also if the controller would
require a higher/lower temperature for the external system. As a result the
external setpoint may thus not be reached.
When operating the temperature system under external control, band
limiting is active. The preset value determines the maximum temperature
difference between the internal bath and the external load. This
adjustment possibility prevents sensitive equipment and temperature
devices from damage.
Heating and cooling power of the instrument are adjustable.
100 % corresponds to the values in the technical specifications of the
equipment.
