The RESOL controller for standard solar thermal systems. DeltaSol® BS persuades by a clear operating concept and is equipped with the newly developed illuminated combined display with systemmonitoring. Flashing symbols for sensors, pumps and valves enable an immediate allocation of temperatures, temperature differences and active actuators. Adjustment and control of the solar system can be easily realised. An extension to the standard version of the controller DeltaSol® BS/3 with 2 standard relays is the version DeltaSol® BS/4 with 1 standard- and 1 semi-conductor relay for pump speed control of the solar pump.

Illuminated system-monitoring-display
Up to 4 temperature sensors Pt1000
optionally: pump speed control, solar operating hours counter and thermostat function
2 basic systems are selectable
Heat balancing, tube collector function
Function control
Housing in outstanding design and easy userfriendly operation

The system controller DeltaSol® BS Plus is preprogrammed for different hydraulic basic systems and equipped with pump speed control, heat quantity balancing and a thermostat function.
The illuminated multi-functional display enables a sytem monitoring for a intuitive and safe controller configuration and comprehensive visualisation of the system status. Simple pictograms provide information on function and operating status of the controller and the system. The controller is equipped with 4 inputs for PT1000 temperature sensors, store temperature limitation and a manual mode (by menu).
For data communication and remote service, the controller is equipped with the RESOL VBus® which opens the bidirectional way to modules, PCs or for data logging. The controller can be configured comfortably by PC with the RESOL Service Center Software. With the embedded thermostat function and real-time clock temperatures can be adjusted individually in different time frames. The controller is easily operated by the 3-key-field below the display.

150mm x 165mm x 24mm
The Smart Display SD3 is designed for simple connection to RESOL controllers via the RESOL VBus® for visualisation of the data issued by the controller: collector and store temperatures as well as energy yield of the solar system. The use of high-efficient LEDs and filter glass assures a high optical brilliance and good readability - even in poor visibility conditions and at a larger distance. An additional power supply is not required.

This additional module enables the acquisition and storage of large amounts of data (such as measuring and balance values of the solar system) over a long period of time.

The DL2 can be configured and read-out with a standard internet browser via its integrated web interface. For transmission of the data stored in the internal memory of the DL2 to a PC, an SD card can be used. The DL2 is appropriate for all controllers with RESOL VBus®.

The datalogger can be connected directly to a PC or router for remote enquiry and thus enables comfortable system monitoring for yield monitoring or for diagnostics of faults.

Visualisation of system states
Yield monitoring
Easy error diagnostics
Easy configuration by integrated web interface for standard internet browsers
Export function for further data processing in spreadsheet programs
Direct connection of PC or router for remote enquiry

The solar cell is used for recording of instantaneous irradiation intensity. The short-circuit flow rises with the increase of irradiation intensity. The relation between the short-circuit flow and the irradiation intensity is directly proportional.
For use with Delta Sol E / ES / M
