In systems with 2 or more stores, loading logic adjustments can be made in this menu.
In systems with 1 store, only the menu item Pump delay is available.
Each loading process will be carried out for the minimum runtime (Solar / Basic setting
/ Store) at least, regardless of the switch-off condition.
Store sequence control type
If the priority store cannot be loaded, the subordinate store next in priority will be checked. If
useful heat can be added, it will be loaded for the circulation time. After this, the loading process
stops and the controller monitors the increase in collector temperature during the loading break
time. If it increases by 2 K, the break time timer will start again to allow the collector to gain more
heat. If the collector temperature does not increase sufficiently, the subordinate store will be
loaded again for the circulation time as before.
As soon as the switch-on condition of the priority store is fulfilled, it will be loaded. If the switch-
on condition of the priority store is not fulfilled, loading of the subordinate store will be continued.
If the priority store reaches its maximum temperature, store sequence control will not be carried
out.
Successive loading type
Successive loading means that the priority store will be loaded up to its maximum temperature. If
it is reached, the next store available for heating will be loaded. If the temperature of the priority
store falls below the set store temperature, the next store will no longer be loaded, regardless of
whether the switch-on conditions of the priority store or of the subordinate store are fulfilled or
not.
If all stores have been loaded to their set temperatures, the same process will take place until the
stores have reached their maximum temperatures.
Spreaded loading option
In multi-store systems without 3-port valves, a spreaded loading function can be activated: As
soon as the adjustable temperature difference between the collector and the priority store is ex-
ceeded, the next store will be loaded in parallel unless it is blocked. If the temperature difference
falls by 2 K below the adjusted value, the pump will be switched off.
