A. Strict Temperature Control
In normal operation, the washing machine heating system works with a temperature control hysteresis below
the programmed target temperature value. This corresponds with line 1 at the fig.4.3.
Some washing machine operators want a strict temperature control in case of hygienic wash cycles.
Example: this means when 70°C is programmed, the linen must be washed at a temperature that doesn't
drop below 70°C. This solution is possible by switching on the „Strict Temperature Control" function. In this
case the wash computer works with a temperature control with a hysteresis above the programmed
temperature value. See line 2 at the fig.4.3.
Strict Temperature Control is not applicable for delicates and woollens, and will not work for a programmed
temperature < 30°C.

B. Temperature Calibration Offset
The temperature sensor of the washing machine can be calibrated with an external temperature
measurement device as reference. The temperature sensor value can be adjusted in a range of +/- 5°C.
For normal washing machine use such calibration is not required.

No
The Strict Temperature Control of the wash computer
makes that the fabrics is washed at same value like
the programmed target temperature.
0
By changing the Temperature Calibration Offset value
the water temperature sensor value is adjusted so that
it gets equal with the value of an external reference
temperature sensor.
