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.
