  • Page 2: Specification

    1.1 General Description 1.1.1 Type The electronic heat cost allocators Sontex 565 / 566 / 868 operate either according to the single sensor principle with start sensor or the double sensor principle. The device has been developed and approved in accordance with the European Standard EN 834:2013.
  • Page 3  For heat cost allocator Sontex 566 Radio, the Sontex radio system (Supercom) is a bidi- rectional system. Reading and programmable by radio.  For heat cost allocator Sontex 868 Radio, the radio module comprises a unidirectional ra- dio transmitter.
  • Page 4 The radio heat cost allocator 566 features a transceiver circuit in the 433 MHz band with integrated antenna. With the Sontex radio system, proven since more than 15 years; it is possible to readout the con- sumption values via a mobile radio modem or via a radio central installed directly in the office.
