System 3000 relay switch insert, potential-free Features: Switching of lights and single-phase motors. Control of electric underfloor heating and thermal actuators in combination with a room temperature controller attachment. Switching of different voltage potentials or external conductors via the potential-free contact. Connection of extensions possible. Automatic switching off of the load. Follow-up times can be set in five stages, cannot be retriggered. Test operation for functional testing. Operation with neutral conductor connection. Combination with RF operating attachment 1-way 2-way for KNX: Switch actuator channel 1-way. Sensor channel 1-way or 2-way. Local control of the System 3000 insert possible. Radio control of other devices for KNX as a sensor possible. Function selection of the insert: Normally open / normally open operation, staircase function with switch-off warning, scene function (16 scenes), lock function, time delays. Extension input as an additional operating point for the System 3000 insert or for radio control of other KNX devices as a sensor possible. Notes: If the ambient temperature is higher than 35 C, the connected load must be reduced.
