8.7. System layout 7 (2 collector arrays, 2 storage reservoirs, 2 pumps, 1 three-way valve)
Description of the system layout:
The solar controller compares the temperatures from collector
sensors F1 (TC1) and F2 (TC2) with the temperatures from the
storage reservoir sensors F4 and F6. If one of the measured
temperature differences exceeds one of the switch-on
temperature differences set here (TDE1 or TDE2), the
corresponding storage reservoir is loaded by means of the
respective speed-controlled solar pump R1 or R2 and the three-
way valve R3. The selected first-priority storage reservoir is
loaded for as long as a loading precondition persists for this
storage reservoir. Afterwards, the second-priority storage
reservoir is loaded by means of batch loading.
