Switch unit with a external temperature sensor RFSTI-11B


EAN: 8595188135849 (230V) | Code: 5235 (230V)


  • The temperature unit measures the temperature by external sensor, and controls the heating circuit (electric underfl oor heating, air conditioning, boiler, etc.).
  • These can be combined with system units: smart RF box eLAN-RF, wireless controller RFTC-50/G or touch unit RF Touch.
  • It measures temperature in a range of -20 to 50 °C and sends it to the system unit in regular 5 min. intervals. It sends a signal upon sudden temperature change.
  • Setting the heat/cool function, hysteresis and off set is performed in the system unit or application.
  • It enables connection of the switched load up to 16 A (4 000 W).
  • Range up to 160 m (in open space), if the signal is insuffi cient between the controller and unit, use the signal repeater RFRP-20 or protocol component RFIO2 that support this feature.
  • Communication frequency with bidirectional protocol RFIO2.
  • The BOX design lets you mount it right in an installation box, a ceiling or controlled appliance cover.
  • External sensor TC (-20 to +80 °C) or TZ (-40 to +125 °C) for length of 3 m, 6 m, 12 m.


  • Supply voltage (frequency): AC 230 V, AC 120 V, AC/DC 12-24V (AC 50/60 Hz)
  • Design: BOX
  • Dimensions: 49 x 49 x 21mm
  • Protocol: RFIO2
