Switch unit with external temperature sensor
RFSTI-111B

The component measures temperature in the range of 15 to 35 °C with external sensor and on the basis of the set temperature switches air conditioning.

DESCRIPTION

  • It is particularly suitable for rooms with a tropical climate.
  • With the Window/Door sensor programmed, when the window/door is opened, the device relay contact is automatically disconnected, thereby saving unnecessary energy consumed for cooling when the window/door is open.
  • It enables connection of the switched load up to 12 A (3000 VA).
  • Up to 4 RFDW-100 detectors can be connected to one RFSTI-111B device.
  • Range up to 160 m (in open space), if the signal is insufficient between the controller and unit, use the signal repeater RFRP-20 or protocol component RFIO2 that support this feature.
  • Communication frequency with 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.
