Switching units with external temperature sensor

Innovation of RFSTI-11B

EAN: 8595188184045 | Code: 8404


  • The temperature element measures the temperature with an external sensor and at the same time controls the heating circuit (electric underfloor heating, air conditioning, boiler…).
  • They can be combined with Detectors, Controllers or iNELS RF Control system components.
  • It measures the temperature in the range -20 to +50 °C and sends it to the system component in a regular 5 min. intervals. It sends a signal when the temperature changes suddenly.
  • The heating/cooling, hysteresis and off-set functions are set in the system component or application.
  • It allows the connection of a switched load up to 8 A (2,000 W).
  • Range up to 200 m (outdoors), in case of insufficient signal between the controller and the device, use the RFRP-20 signal repeater or component with the RFIO2 protocol that supports this function.
  • Communication with bidirectional RFIO2 protocol.
  • The BOX version offers installation directly in the installation box, ceiling or cover of the controlled appliance. Easy installation thanks to screwless terminals.
  • External sensor TC (-20 to +80 °C) or TZ (-40 to +125 °C) with a length of 3 m, 6 m, 12 m.


  • Supply voltage: 230 V AC (50-60 Hz)
  • Temperature measurement range: -20 ... +50 °C
  • Output: 1x switching, 8 A
  • Dimensions: 43 x 44 x 22 mm
  • Communication protocol: RFIO2
