1 normally open contact, not potential-free, 10A/250V AC, 2000 watt incandescent lamps, delay on release with switch-off warning and permanent light with push button can be activated. With integrated current measurement up to 10A. Encrypted radio, bidirectional radio and repeater function can be activated. Standby loss only 0.8 watts. For flush mounting. 45mm long, 45mm wide, 33mm deep. Supply and switching 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. The integrated current measurement measures the apparent power from approx. 10VA to 2300VA with the contact closed. A radio telegram is sent to the Eltako building radio within 30 seconds of the load being switched on and after a change in power of at least 5%, as well as cyclically every 10 minutes. Evaluation on the computer with the building radio visualization and control software GFVS. GFVS-Energy supports up to 100 transmitter modules, GFVS 4.0 up to 250 transmitter modules. 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 confirmed with a radio telegram. This radio telegram can be taught in other actuators, the GFVS software and universal displays.
