2. If priority Su 1 or Su 2 is adjusted, the priority store will be loaded up to
its maximum temperature. If the maximum temperature is reached, the second
store will be loaded. If the temperature of the rst store falls below SMAX,
the second store will no longer be loaded, regardless of whether the switch-on
conditions of the priority store or of the subordinate store are fullled or not.
3. In systems with 2 pumps, both stores will be loaded if the corresponding switch-
on conditions are fullled if PRIO 0 is adjusted. In systems with 3-port valves,
the store with the lowest temperature will be loaded rst until its temperature
is by 5 K above the other store. Loading will be switched to the other store.
Then, the 2 stores will be loaded alternately in steps of 5 K.
Successive loading option
Successive loading means that the priority store will be loaded up to its maximum
temperature. If it is reached, the second store will be loaded. If the temperature
of the rst store falls below the maximum temperature, the second store will no
longer be loaded, regardless of whether the switch-on conditions of the priority
store or of the subordinate store are fullled or not.
Spreaded loading option
In 2-store systems with 2 pumps, a spreaded loading function can be activated:
As soon as the adjustable temperature difference DTSE between the collector
and the priority store is reached, the second store will be loaded in parallel unless
it is blocked. If the temperature difference falls by 2 K below DTSE, the pump is
switched off.
The collector temperature has to be higher than the store temperature.
Loading logic
In systems with 2 stores or store loading in layers, store sequence control can be
adjusted. In 1-store systems, only the menu item PDELA will be available.
