Radio actuator 230V. Without N-connection, 1+1 normally open contacts not potential-free 4A/250V AC, for roller shutters and shading elements. Encrypted radio, bidirectional radio, and repeater function can be activated. Standby loss is only 0.8 watts. Designed for installation. 45 mm long, 45 mm wide, 33 mm deep. Supply, switching, and control voltage locally 230V. Without N-connection, therefore not suitable for all motors. In the event of a power failure, it will be turned off as defined. In addition to the radio control input via an internal antenna, this radio actuator can also be controlled locally with a possibly mounted conventional 230V control button. Encrypted sensors can be learned. Bidirectional radio and/or a repeater function can be activated. Any change of state and received central control telegrams will then be confirmed with a radio telegram. This radio telegram can be learned 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. After that, the desired function of this pulse group switch is selected: GS1 = group switch with button control and fallback delay in seconds. A radio button with the function Up-Hold-Down-Hold can be learned as a universal button just like the local button, as well as a radio button like a roller shutter double button as a directional button with pressing up for Up and pressing down for Down. A short tap interrupts the movement immediately. Central control can be executed dynamically with or without priority. The LED accompanies the learning process according to the operating instructions and indicates radio control commands during operation by briefly flashing.
