DeltaSol<sup>®</sup> SLT System controller

DeltaSol® SLT System controller

The DeltaSol® SLT effortlessly controls even complex systems and enables adaptation to the individual system requirements. Numerous pre-programmed optional functions such as thermal disinfection or zone loading can be combined and parameterised. It is also possible to directly choose from 27 pre-programmed basic systems. The operation via 2 main buttons and 1 adjustment dial, the Lightwheel®, follows the well-known operating concept. The manual mode and the holiday function can be activated by pressing a single button
