  System 7: 1 collector array – 2 storage tanks –
intelligent valve control
Description of the solar function: When the switch-on temperature
difference between the collector array A1 (T1) and one of the two
storage tanks B1, B (T, T3) is exceeded, the solar circuit pump R1 is
switched on and the switching valve R is set to the correct position
depending on the storage tank to be loaded. Both storage tanks B1, B
are loaded one after the other, according to the priority control (chapter
7.5 "Storage tank priority"), until either the relevant switch-off tempera-
ture difference between the collector array A1 (T1) and storage tanks B1,
B (T, T3) is reached, or a safety limit is reached.
NOTE
When no voltage is on the system, the switching valve R must be set
to storage tank B1.
Loading strategy of solar circuit pump R1: In the factory, tempera-
ture differential control is chosen as the loading strategy for the storage
tanks B1, B. It can be adjusted or changed to target temperature con-
trol using the "Parameters" menu (chapter 7.4 "Parameters").
Activating the system: see chapter 7.. "Selecting a system".
