Digital settable multifunction impulse switch with integrated relay function. Standby loss 0.03–0.4 watt only. Simply connect the neutral conductor to the terminal (N) and L to 1(L) and/or 3(L) for this. This results in an additional standby consumption of only 0.1 Watt. Universal control voltage 8 to 230V UC. Supply voltage is same as the control voltage. The functions are set with the keys MODE and SET as described in the operating instructions. They are indicated on the display and can be blocked if required. The accrued switch-on time is continuously displayed. By using bistable relays coil power loss and heating is avoided even in the on mode. The switched consumer may not be connected to the mains before the short automatic synchronisation after installation has terminated. Only impulse switch functions: After a power failure the system is disconnected in a definite sequence or the switch position is kept depending on the setting (then + on the display next to function abbreviations).
