Solar and differential temperature controllers

DeltaSol® DB

DeltaSol DB The DeltaSol® DB is a differential temperature controller for solar drainback systems. Depending on the product version, it provides speed control, heat quantity measurement, etc. The DeltaSol® DB is available in the versions 1 to 4. The DB/3 and DB/4 controllers are additionally equipped with a booster function for the quick filling of the system using a second pump. For data communication, the DeltaSol® DB is equipped with the RESOL VBus®.
