  System 9: 1 collector array – 1 swimming pool
with external heat exchanger
Description of the solar function: The solar circuit pump R1 is switched
on as soon as the switch-on temperature difference between the col-
lector array A1 (T1) and the swimming pool C1 (T) is reached. When
the switch-off temperature difference or a safety limit is reached, the
solar circuit pump R1 switches off again. The swimming pool pump
R is switched on as soon as the temperature difference between the
external heat exchanger F1 (T3) and the swimming pool C1 (T) reaches
the switch-on temperature difference. When the switch-off temperature
difference between the external heat exchanger F1 (T3) and the swim-
ming pool C1 (T) or a safety limit is reached, the swimming pool pump
R switches off.
Loading strategy of solar circuit pump R1: In the factory, the load-
ing strategy of solar circuit pump R1 is set to temperature differential
control. This cannot be altered.
Loading strategy of swimming pool pump R2: It is not possible to
select whether temperature differential control or target temperature
control is to be used as the loading strategy. Swimming pool loading
pump R operates according to the switch-on and switch-off tempera-
ture difference parameter values.
Activating the system: see chapter 7.. "Selecting a system".
