7.6.1. ATC STATUS - YES / NO
7.6.2. CALIBRATION TYPE: 1 -/ 2 -/ 3 POINT
Menu functions
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.
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 VFD-DISPLAY.
Pairs of values:
TMPVAL 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).
CALVAL 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<.
