ATC SENSOR - INTERNAL / EXTERNAL
In the first submenu the ATC function is set for the >INT< internal or
>EXT< external temperature sensor.
Calibration can be carried out for the internal temperature sensor and for
the external temperature sensor connected to the socket „ext. Pt100“.
The recirculating cooler is able to store both parameter sets. However,
only the one set under this menu item is indicated.

ATC STATUS - ON / OFF
In the second submenu the ATC function for the temperature sensor
selected above is activated >ON< or deactivated >OFF<.
>OFF< The controller of the recirculating cooler uses the original curve
of the temperature sensor.
Important:
During the calibration process > OFF < needs to be set.
>ON< The controller of the recirculating cooler uses the new calibration
curve.

In the ATC STATUS > ON<, the ATC calibration curve always affects
the effective working temperature (also the one set via the interface).

CALIBRATION ART: 1, 2, 3-point calibration
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 calibration type also determines the number of pairs of values
indicated on the VFD COMFORT-DISPLAY.

2 values per calibration point
TTEMP X: Temperature on circulator (actual value TT) 1 or 2 or 3
Defined temperature value of the calibration point.
This value is simultaneously stored with > CTEMP < and can be
indicated for control purposes.
CTEMP X:
Calibration temperature (actual value CT) 1 or 2 or 3
The „Calibration value“ is determined with a temperature measuring
device and stored under menu item > CTEMP <.
