Encrypted radio, bi-directional radio and repeater function can be activated. Stand-by loss only 0.8 watts. For panel mounting. 45mm long, 45mm wide, 33mm deep. Contact switching in zero crossing to protect the contacts and consumers. This wireless actuator as a staircase light delayed-off switch has the most modern hybrid technology developed by us: We have combined the wear-free reception and evaluation electronics with a bistable relay that switches at zero crossing. This means that there is no coil power loss and no heating, even when the motor is switched on. 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 staircase light delay
