Loading logic
Solar / Basic settings / Loading logic
Store sequence control:
If the priority store cannot be loaded, the subordinate
store next in priority is checked. If useful heat can be
added, it will be loaded for the circulation time (
Circ.
– factory setting 15 min). After this, the loading pro-
cess stops and the controller monitors the increase in
collector temperature during the loading break time
Load. break
. If it increases by 2 K, the break time
starts again to allow the collector to gain more heat.
If the collector temperature does not increase suffi -
ciently, the subordinate store will be loaded again for
the
Circ. time
as before.
As soon as the switch-on condition of the priority
store is fulfi lled, it will be loaded. If the switch-on con-
dition of the priority store is not fulfi lled, loading of
the subordinate store will be continued. If the priority
store reaches its maximum temperature, store se-
quence control will not be carried out.
If store sequence control is active and the system
switches to load the priority store, the parameter
Load. break
also acts as a stabilisation time, during
which the switch-off condition is ignored while the
system operation is stabilising.
