1 normally open contact, potential-free 10A/250V AC, 230V LED lamps up to 400W, incandescent lamps 2000W. Delayed release with switch-off warning and permanent light button can be activated. Encrypted radio, bidirectional radio and repeater function can be activated. 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. 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 in status and incoming central control telegrams are then confirmed with a radio telegram. This radio telegram can be taught into other actuators, professional smart home controllers and universal displays. Scene control: With one of the four control signals of a button with a double rocker that has been taught in as a scene button, several FSR61s can be switched on or off for a scene. With the upper rotary switch in the LRN position, up to 35 radio buttons can be assigned, one or more of which are central control buttons. In addition, radio window/door contacts with the function of making or breaking when the window is open, radio outdoor brightness sensors FAH and radio motion detectors FBH. The desired function of this impulse switching relay is then selected: ER = switching relay. ESV = impulse switch. If necessary with release delay, then + button permanent light = ESV with button permanent light. +Switch-off advance warning = ESV with switch-off advance warning. +Pushbutton permanent light and switch-off advance warning = ESV with pushbutton permanent light and switch-off advance warning. When the pushbutton permanent light is switched on, you can press the button for longer than 1 second to set the light to permanent. This is automatically switched off after 2 hours or can be switched off by pressing the button. When the switch-off advance warning is switched on, the lighting flickers starting around 30 seconds before the time expires and a total of 3 times at increasingly shorter intervals. If the switch-off advance warning and pushbutton permanent light are switched on, the switch-off advance warning only occurs after the permanent light has been switched off automatically. The lower rotary switch can be used to set the release delay in the ESV function from 2 to 120 minutes. In the infinite position, normal impulse switch function ES without release delay, without pushbutton permanent light and without switch-off advance warning.In the ER = switching relay position of the other rotary switch, this second rotary switch fulfils a safety and energy saving function in settings other than infinite: If the switch-off command is not recognised, e.g. because the button is stuck or has been pressed too quickly, the relay switches off automatically after the time, which can be set between 2 and 120 seconds, has elapsed. If an FTK has been programmed, this time function is switched off. Twilight switch with programmed radio outdoor brightness sensor FAH and motion detection with programmed radio motion detector FBH in accordance with the operating instructions. The LED accompanies the programming process in accordance with the operating instructions and indicates radio control commands during operation by flashing briefly.
