Radio actuator 230V. Without N connection, 1+1 normally open contact not potential free 4A/250V AC, for roller shutters and shading elements. 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, switching and control voltage 230V. Without N connection, therefore not suitable for all motors. If the supply voltage fails, it is switched off in a defined manner. In addition to the radio control input via an internal antenna, this radio actuator can also be controlled locally with a conventional 230V control button that may be mounted in front of it. 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 into other actuators, the GFVS software 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. The desired function of this impulse group switch is then selected: GS1 = group switch with button control and release delay in seconds. A radio button with the up-stop-down-stop function can be taught in as a universal button like the local button, or a radio button like a roller shutter double button can be taught in as a direction button with pressing up to up and pressing down to down. A short tap stops the movement immediately. Dynamic central control with and without priority can be carried out. The LED accompanies the teaching process in accordance with the operating instructions and indicates radio control commands during operation by flashing briefly.
