Solar controller DeltaSol<sup>®</sup> SLL

Solar controller DeltaSol® SLL

The DeltaSol® SLL is the smallest controller of the SL series. Its equipment is optimised for small and medium-sized solar thermal and heating systems, 10 pre-configured basic systems are available. The DeltaSol® SLL is also the first controller of its category to offer the automatic function control according to the VDI 2169 directive. Additionally, it is equipped with a potential-free extra-low voltage relay for backup heating demand and a V40 flowmeter input for heat quantity measurement.
