BAND HIGH / LOW – Band limitation
The band limitation is active during external control. Varied, practice-
oriented setting are feasible for heat-up and cool-down phases.
Setting range: 0 °C ... 200 °C
BAND HIGH
and BAND LOW allow for the limitation of the difference
between the temperatures in the internal bath and the external system to
any maximum value for the heat-up and cool-down phase.
During the heat-up phase this difference value is always added to the
actual external temperature. During the cool-down phase the difference
value is subtracted.
