System 8: Solar system with 1 store and afterheating with solid fuel boiler
The controller calculates the temperature difference between collector sensor
S1 and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference, the pump (R1) will be switched on and the store
will be loaded until the switch-off temperature difference or the maximum store
temperature is reached.
With another temperature differential function (S5 heat source/S3 heat sink), af-
terheating of the store with a solid fuel boiler can be carried out via another pump
(R3).
