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 (T2) 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
R2 is switched on as soon as the temperature difference between the
external heat exchanger F1 (T3) and the swimming pool C1 (T2) 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 (T2) or a safety limit is reached, the swimming pool pump
R2 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 R2 operates according to the switch-on and switch-off tempera-
ture difference parameter values.
Activating the system: see chapter 7.2. "Selecting a system".
