Wireless extractor hood control. 1 normally open contact, not potential-free 10A/250 V AC. Standby loss only 0.4 watts. For built-in installation. 52x53mm, 22mm deep. The connection terminals are plug-in terminals for conductor cross-sections from 0.2mm to 2.5mm. Up to 32 wireless universal buttons and wireless window contacts can be programmed using the convenient tap technology. Only sensors that report that the window is actually open or tilted are permitted. Otherwise there is a risk of poisoning! Bidirectional radio can be activated. Local supply, switching and control voltage 230 V. Contact switching at zero crossing. Bistable relay, so there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. If the supply voltage fails, the switching state is retained. When the supply voltage returns, the switch is switched off in a defined manner. The extractor hood motor can only be switched on when the window is open. If the window is closed, the relay switches the motor off. However, if the motor is switched off before the window is closed, any integrated lighting that may be switched on remains switched on and can be switched on and off using the extractor hood switch. If the motor is switched on in addition to the lighting when the window is closed, the relay switches off. The integrated lighting can be switched on with a radio button or a local conventional 230 V control button (a glow lamp current is not permitted) even when the window is closed and the relay is switched off. Radio window-door contact with battery 75x25x12mm, pure white. The window-door contact FTKB supplies itself with a solar cell from 100 lux of daylight, otherwise for several years with a CR2032 button cell. When closing and opening, the relevant telegram is sent twice in quick succession. The current status telegram is sent cyclically approximately every 8 minutes. Fastened by gluing. Dimensions window-door contact LxWxH: 75x25x12mm, dimensions magnet LxWxH: 37x10x6mm.
