individual aggregates.

Changeover time 00:00...23:59
You can set the changeover time (weekday, time) to avoid changeover to another
lead aggregate at undesirable times (e.g. weekend).
Periodic changeover set to "Auto" means that changeover by operating hours can
be activated. In this case, changeover of the lead aggregate occurs in dependence
of the lead aggregate's operating hours.
Changeover by operating hours balances out the number of operating hours
between the individual aggregates.

----, 1...1440 h
interval
There is no changeover by operating hours if "Changeover interval" is set to "---".
Operating hours changeover can be carried out with or without a changeover day
and time. To do this, both changeover day and time must be activated.
After a set time, the next aggregate is selected as lead aggregate upon
changeover time defined in periodic changeover.
Operating hours are counted only if:
 Modulating
aggregates are connected.
 Control of the modulating aggregate
Sequence selector set to "Auto" means that continuous changeover of the lead
aggregate can be activated.
The aggregate switched on first is switched off if several aggregates are switched
on and the load drops.
First-in first out balances out the number of operating hours between the individual
aggregates.
