ETS product family: Illumination
Product type: Dimmer

39001 1S U

Intended use

  • Switching and dimming of lighting
  • Reading in switching states of installation switches or push-buttons and other floating contacts at inputs 1…3
  • Signal evaluation of condensation (ref.-no.: BTS 01) and leakage sensors (ref.-no.: LES 01) at inputs 1…3
  • Acquisition of temperature values via NTC temperature sensor at input 3 (ref.-no.: FF 7.8)
  • Installation in flush box according to EN 60670-1


Product characteristics

  • Output can be operated via KNX telegrams or extension inputs
  • Three extension inputs for connecting floating contacts or dew/leakage sensors. NTC temperature sensor can be connected to input 3.
  • Supply via bus, no additional power supply necessary
  • KNX Data Secure compatible with ETS 5.7.3 or higher
  • Can be updated with the ETS Service App


Dimming operation characteristic

  • Automatic or manual setting of the dimming principle suitable for the load
  • Protected against no-load, short-circuit and overheating
  • Signal in the event of a short-circuit
  • Feedback of the switching position and the dimming value
  • Parameterisable switch-on and dimming behaviour
  • Time functions: switch-on delay, switch-off delay, staircase lighting timer with pre-warning function
  • Light scene operation
  • Operating hours counter
  • Power failure longer than approx. 5 seconds leads to switch-off of the dimmer actuator. Depending on the parameter setting, the connected load is calibrated after voltage return.
  • Power extension possible by means of power boosters (ref.-no. ULZ 1755 REG)


Characteristics satellite input

  • Operating functions switching, dimming (including colour temperature), controlling blinds, value transmitter (1 byte, 2 byte, 3 byte and 6 byte incl. RGBW und colour temperature presets), scene extension etc.
  • Disabling function
  • Debounce time adjustable


Logic function characteristics

  • Logic gates
  • Transformer (conversion)
  • Disabling element
  • Comparator
  • Limit value switch
