Solar and differential temperature controllers

DeltaSol® BS Plus

DeltaSol BS Plus The RESOL DeltaSol® BS Plus system controller is pre-programmed for different systems and is equipped with a energy metering function, a realtime clock and the RESOL VBus®. The multi-functional and illuminated display enables system-monitoring for intuitive and safe controller configuration and comprehensive visualization of the system status. Simple pictograms provide information on function and operating status of the controller and the system. This version is equipped with 4 inputs for Pt1000 temperature sensors, tank temperature limitation and manual operation mode. The central element is the 3-key-field below the display.
