Operating time
Operating mode S6 is supplemented by specification of the ON time (ED) in %.
The operating time is calculated as follows:
ED
Cyclic duration factor in %
ΔtP
Operating time with constant load

Cyclic duration factor
The values specified in the documentation have been determined on the basis
of the following parameters:
Cycle duration: 15 min
Operating time (ED): 25%
If valid, conditions deviating therefrom are marked accordingly.
