Hysteresis adjustment to achieve the most accurate regulation
Very complicated regulation algorithm is used to achieve the required temperature. 3 hysteresis ranges are used and
the heating output is regulated according to them, in addition its amplitude is changed linearly in dependence on
temperature and on cooling compressor closing. Hold generally – if the volume of the bath is bigger, one has to adjust
smaller hysteresis. Procedure of hysteresis adjustment is following:
1)
Press the key s OFF and ENTER at the same time
2)
There is text „dig value of tem“ on the first line and the value on the second line.
3)
There is text „point 1 - digital“ on the first line and the value on the second line. We do not calibrate the
temperature sensor now therefore press the key „OFF“.
4)
There is text „point 1 - temp“ on the first line now and the value on the second line. We do not calibrate the
temperature sensor now therefore press the key „OFF“.
5)
There is text „point 2 - digital“ on the first line now and the value on the second line. We do not calibrate the
temperature sensor now therefore press the key „OFF“.
6)
There is text „point 2 - temp“ on the first line now and the value on the second line. We do not calibrate the
temperature sensor now therefore press the key „OFF“.
7)
There is text „HYSTER1_0=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER1_0“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER1_0 is preadjusted by the manufacturer as 000.30.
8)
There is text „HYSTER1_100=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER1_100“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER1_0 is preadjusted by the manufacturer as 000.10.
9)
There is text „HYSTER2_0=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER2_0“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER2_0 is preadjusted by the manufacturer as 000.15.
10)
There is text „HYSTER2_100=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER2_100“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER2_100 is preadjusted by the manufacturer as 000.05.
11)
There is text „HYSTER3_0=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER3_0“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER3_0 is preadjusted by the manufacturer as 000.05.
12)
There is text „HYSTER3_100=“ on the first line now and the value on the second line. Overwrite the value
with the help of keys + (increase ) or – (decrease) to adjust „HYSTER3_100“ as required. Press the key
„OFF“ to set the required value. Hysteresis „HYSTER3_100 is preadjusted by the manufacturer as 000.02.
The hysteresis is adjusted now.
