9.7 Setting the priority
Functionality
The priority determines the sequence in which the storage tanks are loaded (only for
systems with more than 1 storage tank). If the higher priority storage tank (first-priority
storage tank) cannot be loaded because the collector temperature is too low, then the
lower priority storage tank (second-priority storage tank) is loaded
1)
. The following
values can be selected:
-1-: only storage tank 1 is loaded.
-2-: only storage tank 2 is loaded.
1-2: storage tank 1 is the first-priority storage tank.
2-1: storage tank 2 is the first-priority storage tank.
1)
Every 30 minutes, the controller checks to see if the first-priority storage tank can be loaded.
Due to the warming of the collector array, this check can take several minutes. On the basis of
the heating process, the controller predicts whether it is possible to load the first-priority storage
tank in a foreseeable period of time.
