Dimplex SOLCU Installation And Operating Instructions Manual page 36

System 14: 1 collector array – 1 storage tank –
1 swimming pool in stand-alone operation
with external heat exchanger –
intelligent valve control
Description of the solar function: When the switch-on temperature
difference between the collector array A1 (T1) and the storage tank B1
(T) or the swimming pool C1 (T3) is reached, the solar circuit pump R1
is switched on and the switching valve R is set to the correct position
depending on the storage tank / swimming pool to be loaded. Either
storage tank B1 or the swimming pool C1 is loaded, according to the
priority control (chapter 7.5 "Storage tank priority"), until either the rel-
evant switch-off temperature difference between the collector array A1
(T1) and the storage tank B1 (T) or swimming pool C1 (T3) is reached,
or a safety limit is reached. The swimming pool pump is controlled exter-
nally.
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 for storage tank: In the
factory, temperature differential control is chosen as the loading strat-
egy for the storage tank B1. It can be adjusted or changed to target
temperature control using the "Parameters" menu (chapter 7.4 "Param-
eters").
Loading strategy of solar circuit pump R1 for swimming pool: In
the factory, the loading strategy for the swimming pool C1 is set to
temperature differential control. This cannot be altered.
Activating the system: see chapter 7.. "Selecting a system".
