Schüco Solar Differential Controllers

The Schüco SDC 204 & SDC 306 differential controllers are designed for maximum system efficiency through simple and user-friendly interface. The SDC controllers are a successful synthesis of use, flexibility and comfort. Engineers have created a new generation of digital solar-thermal differential control units with a claim to unprecedented function in design, technology and operation.

These controllers are shipped pre-programmed for different solar and heating systems, which can be adapted to individual systems and requirements by adjustable functions and options. A large, clearly arranged LCD display ensures ease of operation using internationally recognized pictograms. In addition, the LCD screen gives the homeowner a variety of real time information including energy production, (kWh) measurements and memory of minimum / maximum collector and tank temperatures.

In addition to its primary function of system operation during the day, the SDC controllers also provide important diagnostic and safety functions. A controller integrated “Quick-Info Guide” clearly describes various fault symptoms, possible causes and remedies. The controllers are shipped with PT-1000 temperature sensors, wall mounting hardware, a seven foot line cord and a spare fuse.
