This function blocks the conventional backup heating of a store that is currently in solar loading.
This function is activated if a previously selected store is being loaded by solar heat.
Solar loading means that store loading is only carried out for energy supply and not for cooling
purposes etc.
If the Stset option is activated, the backup heating will only be suppressed when the store
temperature exceeds the set store temperature.

With this function, e.g. a valve can be controlled in parallel to a solar pump via a separate out-
put.
Switch-on condition for the solar parallel relay function is that one or more of the selected
stores is being loaded. If one of the selected stores is being loaded, the parallel output will be
energised.
The parallel relay function operates regardless whether the store is subjected to regular solar
loading or to a loading caused by a solar optional function (such as the collector cooling).
NOTE:
If a relay is in the manual mode, the selected parallel output will not be energised.
