Microcontroller technology with 13 different functions: impulse switch, staircase light control, slow ON/OFF dimmer, interval timer, speed adjustment for fans, etc… Suitable for both resistive and inductive loads (light bulbs, high-voltage halogen lighting and low-voltage halogen lighting with ferromagnetic transformer) "Soft Start" prolongs the life of the bulbs, an advanced security system with fault indication automatically deactivates the module if the load or no-load behaves too inductively. Can be operated from several locations, simply by the parallel connection of push buttons. 2 delay times (anywhere between 5 sec. to 2 hours each) can be programmed through the learning mode. Memory is protected against power failures, equipped with fuse and key for function selection. Mains suppressor according to EN55015 norms.
