TRANSCRIPT
The digital controller generation SDR is distinguished by high functionality, perfect styling and innovative solutions. The three SDR2, SDR3 and SDR6+ modules represent state-of-the-art solar technology and offer numerous solu-tions in the areas of user friendliness and unit safety.
An optional yield measurement kit keeps you up-to-date with the energy generated by the solar energy system. The RPM-regulated output for the circulation pump and the mo-nitoring of the inputs for sensor breakage complete the capability characteristics of this modern digital controller for solar thermal applications.
FEATuRES:
n Large LCD, displays all operating datan Easy-to-understand interface (symbols)n SDR6+: 5 display languages selectablen Easy operation via 4-button paneln Displays yield of the solar energy system (optional)n System errors are shown on the display (sensor and
circulation pump monitoring)n Optimum energy yield by means of variable pump
speedn Collector protection function (increases the lifespan
and the energy yield of the system)n Electronics with the lowest energy consumptionn Quick guide and connection diagram on the devicen Optimal serviceabilityn Overvoltage protection on the power supply and the
sensor inputsn Backup heating function
