9.7.5 Tolerance range
You can specify a temperature program tolerance range for each program section with different values for
the tolerance minimum and maximum. When the actual value exceeds the given threshold, the program is
interrupted. This is indicated on the display (see below). When the actual temperature is situated again
within the entered tolerance limits, the program automatically continues. Therefore, the duration of the
program may be extended due to the programming of tolerances.
Programming of tolerances may extend program duration.
An entry of “-99999” for the tolerance minimum means “minus infinite” and an entry of “999999” for the
tolerance maximum means “plus infinite”. Entry of these values will never lead to program interruption.
The entry of “0” for the tolerance minimum and/or maximum deactivates the respective tolerance function.
When requesting rapid value transitions, we recommend not programming tolerance values in order to
enable the maximum heating-up or cooling-down speed.

•
Select the field “Tolerance band min” and enter the desired lower tolerance band value. Setting range: -
99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
•
Select the field “Tolerance band max” and enter the desired upper tolerance band value. Setting range:
-99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
If the actual temperature value is outside the program tolerance range the whole program course is inter-
rupted. During this program interruption time the controller equilibrates to the set-points of the current
section.
The screen header indicates “Program pause (tolerance band)”. The program runtime indication flashes
and does not proceed any further.
When the actual temperature value is back within the entered program tolerance range, the program con-
tinues automatically.
