If the time interval between two defrost cycles is changed
when the system is in operation, the new time interval will
not be applied until after the next time defrosting has
occurred.

☛
During the defrosting process, the last current tempe-
rature before defrosting started is retained in the dis-
play. After defrosting, the display returns to the instan-
taneous temperature when the stored value is reached
again or, at the latest, after time E10 has elapsed.

7.2 Sensor calibration (parameter E06)
The sensor can be calibrated.
Note on sensor calibration: Additional line resistance of 7
q
in each
case, caused by sensor cable extension, results in a change in the
temperature display by +1K.
How to proceed: Measure the temperature with a calibrated
thermometer or submerge the sensor in well-mixed ice water (0 °C).
Compare the measured temperature with the temperature shown on
the unit display.
If the measured temperature is lower than the one displayed, set the
negative difference as the programming value (e.g. - 2 K).
