System 2: 1 tank + 1 solid fuel boiler

Description:

The solar circuit pump (P1) is switched on as soon as the switch-on temperature difference
(DT1O) between the collector array (T1) and the storage tank (T2) is reached. If the
temperature difference between the collector array (T1) and storage tank (T2) drops below
the switch-off temperature difference (DT1F), or the temperature of storage tank reaches
its preset maximum storage temperature, then the solar circuit pump (P1) is switched off.
