APPLICATIONS CAPACITY Max.number of collectors:1 Max.number of storage tanks:1 Max.number of relays:4 Max.number of sensors:5 Max.number of application system:1 APPLICATIONS 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. I f 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: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.
