1 normally open contact not potential-free 10A/250V AC, incandescent lamps 2000 watts, LED and ESL up to 400 watts. With integrated current measurement up to 10A. Encrypted radio, bidirectional radio and repeater function can be switched on. Standby loss only 0.8 watts. Adapter plug for German safety socket. With increased contact protection. Supply and switching voltage 230V. If the supply voltage fails, the switching state is retained. When the supply voltage returns, it is switched off in a defined manner. After plugging in, wait for the automatic short synchronization before plugging in the switched consumer. This radio actuator has the most modern hybrid technology developed by us: We have combined the wear-free reception and evaluation electronics with a bistable relay. With the integrated current measurement, the apparent power from approx. 10VA to 2300VA is measured with the contact closed. A radio telegram is sent to the Eltako building radio within 30 seconds of the load being switched on and after a change in power of at least 5%, and cyclically every 10 minutes. Evaluating and linking scenes and automations via Professional Smart Home Controller. Encrypted sensors can be taught in. Bidirectional radio and/or a repeater function can be switched on. Every change in status and incoming central control telegrams are then confirmed with a radio telegram. This radio telegram can be taught in to other actuators, to Professional Smart Home Controllers and to universal displays. Up to 35 radio buttons can be assigned using the left LRN button, either as universal buttons, direction buttons or central control buttons. Up to 35 radio window-door contacts FTK or window handle sensors FFG7B can be taught in to control extractor hoods or similar. Several FTKs or window handle sensors FFG7B are linked together. If an FTK or window handle sensor FFG7B is taught in, control commands from any taught-in buttons are no longer executed. The right button can be used to switch the device on and off manually. The LED accompanies the teaching process in accordance with the operating instructions and indicates radio control commands during operation by flashing briefly.
