Solar and differential temperature controllers

DeltaSol® BS

DeltaSol BS The RESOL controller for standard solar thermal systems. The DeltaSol® BS controller provides a clear operating concept and is equipped with the newly developed illuminated combined display with system-monitoring.Flashing symbols for sensors, pumps and valves enable an immediate allocation of temperatures, temperature differences and active actuators.The DeltaSol® BS controller is available in 4 versions, depending on the demands. Details concerning the type and number of the relays as well as additional functions are shown in the table.
