difference between the collector array A1 (T1) and the storage tank B1
(T) or the swimming pool C1 (T3) is reached, the appropriate solar cir-
cuit pump R1 or R is switched on. Either storage tank B1 or the swim-
ming pool C1 is loaded, according to the priority control (chapter 7.5
"Storage tank priority"), until either the relevant switch-off temperature
difference between the collector array A1 (T1) and storage tank / swim-
ming pool B1, C1 (T, T3) is reached, or a safety limit is reached. The
swimming pool pump is controlled externally.
Loading strategy of solar circuit pump R1: In the factory, temperature
differential control is chosen as the loading strategy for storage tank B1.
It can be adjusted or changed to target temperature control using the
"Parameters" menu (chapter 7.4 "Parameters").
Loading strategy of solar circuit pump R2: It is not possible to select
whether temperature differential control or target temperature control
is to be used as the loading strategy. Solar circuit pump R operates
according to the switch-on and switch-off temperature difference
parameter values.
Activating the system: see chapter 7.. "Selecting a system".
