System variant 2: Storage tank heat exchanger
The storage tank charging pump LP1 runs if the storage tank
temperature SF1 is higher around the adjusted temperature
threshold (lower rotary switch) than the storage tank
temperature SF2 and the storage tank temperature SF2 is not
greater than the adjusted storage tank maximum temperature
(upper rotary switch).

SF2 Sensor 2
System variant 3: Raise return flow
The switching valve UV (3-way valve) routes the heating circiut
return flow about the storage tank if the storage tank
temperature SF1 is higher around the adjusted temperature
threshold (lower rotary switch) than the heating circiut return
flow temperature RüF.
The upper rotary switch has no function in this system variant.

System variant 4: Charging pump control I
The storage tank charging pump LP1 runs if the boiler
temperature KF1 is higher around the adjusted temperature
threshold (lower rotary switch) than the storage tank
temperature SF1 and the storage tank temperature SF1 is not
greater than the adjusted storage tank maximum temperature
(upper rotary switch).
