System 3000 relay switch insert 2-wayFeatures: Switching of lighting and single-phase motors. Adaptive zero-point switching. Connection of extensions possible. Test operation for function testing. Operation with neutral conductor connection.Combination with System 3000 operating top 2-way: Switching of two independent outputs. Time function for output a2 can be set.Combination with System 3000 operating top: Output a2 switches depending on output a1, e.g. to switch ventilation on depending on the lighting and switch it off with a delay. Switch-on delay for output a2 can be set. Follow-up time for output a2 can be set.Combination with KNX RF operating top 1-way 2-way: Switch actuator channel 1-way. Sensor channel 1-way or 2-way. Local control of the System 3000 insert possible. Radio control of other KNX devices as sensors possible. Function selection of the insert: Normally open or normally open operation, staircase function, scene function, lock function, time delays. Extension input as an additional control point for the System 3000 application or for radio control of other KNX devices as a sensor. Notes: In combination with a standard motion detector attachment, memory operating attachment, blind and timer display or blind and timer BT, the 2-way relay switch insert behaves as if it were an operating attachment. In combination with a comfort BT motion detector attachment or 360° presence and motion detector attachment BT, output a1 switches on depending on the brightness and output a2 switches on independently of the brightness and with a time delay when there is movement. If the ambient temperature is higher than 25 C, the connected load must be reduced.
