Solar & system controllers
Solar controller DeltaSol® BS series
The RESOL controllers for standard solar thermal systems. The DeltaSol® BS series provides a clear operating concept. The intuitive commissioning menu leads you through the initial configuration in only a few steps. The system selected is shown on the display, the status of the individual components is indicated by means of flashing codes. The DeltaSol® BS series is available in 3 versions, depending on the demands. Details concerning the number of the relays as well as additional functions are shown in the technical data.
