1 normally open contact, potential-free 10A/250V AC, 230V LED lamps up to 400W, incandescent lamps 2000W*. Encrypted radio, bidirectional radio and repeater function can be switched on. Standby loss only 0.8 watts. For built-in installation. 45mm long, 45mm wide, 33mm deep. Local supply and control 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. This radio actuator has the most modern hybrid technology we have developed: We have combined the wear-free reception and evaluation electronics with a bistable relay. This means that even when switched on, there is no coil power loss and no heating as a result. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. In addition to the radio control input via an internal antenna, this radio actuator can also be controlled locally with a conventional control button that may be mounted in front of it. A glow lamp current is not permitted. Encrypted sensors can be taught in. Bidirectional radio and/or a repeater function can be switched on. Every change of status and incoming central control telegrams are confirmed with a radio telegram. This radio telegram can be taught in to other actuators, Professional Smart Home Controllers and universal displays. With the upper rotary switch in the LRN position, up to 35 radio buttons can be assigned, including one or more central control buttons. In addition, radio window-door contacts (FTK) with the function of making or opening when the window is open. If a direction button is taught in, a function (e.g. TI) can be started with the upper button (START) and stopped with the lower button (STOP). This is then used to select the desired function of this radio actuator. The changeover is visualized by the LED flashing. RV = release delay. AV = response delay. TI = clock generator starting with pulse. IA = pulse-controlled response delay. EW = switch-on timer. The time can be set from 0.5 seconds to 60 minutes using the lower rotary switch. The LED accompanies the programming process in accordance with the operating instructions and indicates radio control commands during operation by flashing briefly. * The maximum load can be used from a delay or cycle time of 5 minutes. For shorter times, the maximum load is reduced as follows: up to 2 minutes to 30%, up to 5 minutes to 60%.
