Output can be also switched off before time (reset) by long pressing of button (longer than 2 sec).
Output relay contact 16 A/AC1 with inrush current up to 80 A enables switching of el. bulbs and also fl uorescent lights.
Operating system switch:
- ON - output is constantly ON (service mode).
- AUTO - timing according to adjusting by potentiometer
in range 30 s - 10 min.
- PROG - timing with time prolongation option by number button
Timing (in mode AUTO and PROG) is possible to be stopped by long pressing of the button (> 2 s).
