4.1.4 Simulation of daily routine
Using a time switch, it is possible to simulate an entire daily routine with sunrise and sunset. To do
this, the parameter "Time between Soft ON and Soft OFF" needs to be set to "Until Soft Off telegram"
(See object 3, soft switching).
The timer switch sends a Soft On telegram (=1) in the morning and a Soft Off telegram (=0) in the
evening to object 3.
