7.1.4 Sensor calibration
The measured values of all of the connected sensors can be changed or reset. When calibrating
a sensor, change the sensor value currently displayed to make it match the temperature (refer-
ence value) measured directly at the point of measurement.
Enter the code number 1999 in the configuration level to calibrate sensors.
To do this, proceeds as follows:
Use a pencil (or similar object) to press the changeover key, a triangle (parameter
level) starts to blink in the top left-hand corner of the display.
Press the arrow keys simultaneously, two triangles (configuration level) start to blink in
the display as well as the currently active system code number.
Press the enter key.
0 0 0 0
appears in the display.
Press the arrow key once. The code number
1999
appears.
Press the enter key to acknowledge this code number.
The symbol for the flow temperature appears in the display together with its current
temperature (initially without calibration).
Press the enter key to acknowledge the sensor shown for calibration.
The actual temperature (used as the reference value) must be read from a thermometer
directly at the point of measurement.
Use the arrow keys until the displayed value matches the reference value.
Press the enter key to acknowledge the corrected temperature value.
Press the arrow key to continue to the next sensor. Proceed with the calibration as
described above.
Press the arrow key to exit the calibration menu.
