The afterheating suppression blocks the conventional
afterheating of a store that is currently in solar loading.
This function is activated if a previously selected
Store is being loaded.
Solar loading means that store loading is only carried
out for energy supply and not for cooling purposes etc.
If the Tset option is activated, the backup heating will
only be suppressed when the store temperature ex-
ceeds Tset.

Parallel relay

With this function, e. g. a valve can be controlled in
parallel to a solar pump via a separate relay.
Switch-on condition for the solar parallel relay func-
tion is that one or more of the selected stores is being
loaded. If at least one of the selected stores is being
loaded, the parallel relay is energized.
The parallel relay function operates regardless whe-
ther the store is subjected to regular solar loading or
to a loading caused by an optional function (such as
the collector cooling).

Note:
If a relay is in the manual mode, the selected
parallel relay will not be energized.
