1 collector array – 1 storage tank – 1 pump and auxiliary heating Description: The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (△Ton) 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 (△Toff), or the temperature of storage tank (T3) reaches the preset maximum storage temperature, then the solar circuit pump ( R1) is switched off. Back-up heating by auxiliary boiler (detailed see paragraph 4.3): Within the preset time section of back-up heating, if the temperature T3 is below the switch-on temperature, then the circulation pump ( H1) of back-up heating is triggered, when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.
