ding process stops and the controller monitors the
increase in collector temperature during the loading
break time Load. break. If it increases by 2 K [4° Ra],
the break time timer starts again to allow the collec-
tor to gain more heat. If the collector temperature
does not increase suciently, 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 fullled, it will be loaded. If the switch-on
condition of the priority store is not fullled, loading
of the second store will be continued. If the priority
store reaches its maximum temperature, sequence
controlled loading 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 timer, during
which the switch-o condition is ignored while the
system operation stabilises.

If the priority store cannot be loaded, the subordina-

be added, it will be loaded for the circulation time
(Circ. – factory setting 15 min.) After this, the loa-
