The figure below shows the switching behaviour of the outputs depending on the threshold values:

Hysteresis
The hysteresis serves to avoid too frequent switching. For example, a hysteresis of 5% and a
threshold of 50% would switch on at 55% and switch off at 45%. If the thresholds are determined
via Delta T, the hysteresis is also given in Kelvin. However, the effect remains the same.
Send outputs cyclically every
With this parameter the cyclical sending of the output can be activated. All output states are sent
cyclically according to the set time.
The following table shows the communication objects for the output of the step switch bit-coded:
