Resol - Model DeltaSol BS Series - Solar Controller

SHARE

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.
