9.5.1. ATC STATUS - YES / NO
In the second submenu the ATC function for the temperature sensor
selected above is activated >YES< or deactivated >NO<.
>YES< (factory setting) The controller of the circulator uses the
original curve of the temperature sensor or the new curve
measured during the ATC calibration.
Important: Set to >NO< during the calibration process
>NO< An ATC calibration is to be carried out.
Important: Set to >YES< after calibration.

In the > ATC STATUS < >YES< the ATC calibration always affects
the current working temperature; also the one set via interface.
9.5.2. ATC - TYPE: 1 -/ 2 -/ 3 POINT
A >1-point<, >2-point< or >3-point< calibration can be carried out.
First geometrically define the location for calibration (measuring point
CT), then determine the temperature values of the calibration points.
The type of calibrations also determines the number of the following
pairs of values indicated on the MULTI-DISPLAY (LED)..
Pairs of values:
tt X: Circulator temperature 1 or 2 or 3 (actual value TT )
The actual temperature of the bath is simultaneously saved with
the “calibration value“ >CALVAL< and can be indicated for control
purposes (value does not flash).
Ct X: Calibration temperature 1 or 2 or 3 (actual value CT )
The „calibration value“ is determined with a temperature measuring
device and saved under menu item >CALVAL<.
