The SCC controllers are intended for regulating a constant inflow or return temperature. They are used for the regulation of the return temperature of solid fuel furnaces as well as for the single- or two-stage charging of the heat supply device.



  • Regulation of return temperature of the solid fuel boilers
  • Supply device charging
  • Operation of a pellet or combined boiler



  • 6 preset hydraulic circuit diagrams;
  • the option for regulating the mixing valve according to the temperature of the piping and the source;
  • pump regulation according to the temperature of the piping and the source
  • the option for simulating system operation;
  • 4 mechanical relays;
  • 2 solid state relays;
  • 7 temperature sensor inputs;
  • 3 free programming outputs;
  • remote control option with the help of SeltronHome system.
