Universal radio actuator with exchangeable antenna. Impulse switching relay with 1 changeover contact, potential-free 10A/250V AC, incandescent lamps 2000W, with DX technology. Bidirectional. Encrypted radio. Standby loss only 0.9 watts. If required, a FA250 or FA200 radio antenna can be connected. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 2 division units = 36mm wide, 58mm deep. Supply voltage 230V. The universal radio actuator combines the functions of a radio antenna module and an actuator as a 1-channel impulse switching relay with DX technology. 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. With the patented Eltako Duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thereby drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to 15 (L). This results in an additional standby loss of just 0.1 watts. Bidirectional radio and/or a repeater function can be switched on. With bidirectional radio, every change in status and incoming central control telegrams are confirmed with a radio telegram. This radio telegram can be taught into other actuators, the GFVS software and the FUA55 universal display. The function of the actuator is set using the lower rotary switch. ER = switching relay. ESV = impulse switch. If necessary with release delay: +button permanent light = ESV with button permanent light switched on, +switch-off early warning = ESV with switch-off early warning switched on, +button permanent light and switch-off early warning = ESV with switch-off early warning and button permanent light switched on. When the button permanent light is switched on, you can press the button for longer than 1 second to set the light to permanent. This switches off automatically after 2 hours or can be switched off by pressing the button. When the switch-off early 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. During this time, you can switch on again. Using the upper rotary switch, the release delay in the ESV function can be set from 2 to 120 minutes. In position 0, normal impulse switch function ES without release delay, without button permanent light and without switch-off early warning. In the ER = switching relay position of the lower rotary switch, this rotary switch fulfils a safety and energy saving function in settings other than 0: If the switch-off command is not recognised, e.g. because the button is stuck or has been pressed too quickly, contact 18 opens automatically after the time has elapsed, which can be set between 2 and 120 seconds. If an FTK has been programmed,this time function is switched off. Universal buttons can be programmed as openers according to the operating instructions. Radio window-door contacts FTK and Hoppe window handles: Function setting ER: Several FTK and (or) Hoppe window handles are linked together, Normally open: If a window is opened, contact 18 closes, all windows must be closed for contact 18 to open (e.g. control of extractor hoods). Normally open: All windows must be closed for contact 18 to close, if a window is opened, contact 18 opens (e.g. for air conditioning control). Twilight switch with programmed radio outdoor brightness sensor FAH and in the function setting ESV. In the time setting 120, contact 18 opens with a 4-minute delay when there is sufficient brightness, in the time setting 0 it opens immediately. Button control is also possible. Motion detection with programmed radio motion detector FBH (slave) and in the function setting ER. With
