How to use

Install the timer in accordance with local electrical regulations, ensuring power is isolated before wiring. Mount the device on the panel or DIN-rail and connect the supply and load per the wiring diagram. Set the current time on the 24-hour dial, then place or remove the trippers around the dial to define on/off intervals. Use the manual override to temporarily force the output on or off without changing the programmed trippers. After programming, restore power and verify switching operation at the set times.

Recommendations

Use the timer within its rated 16 A, 230 V limits and avoid switching loads that exceed its capacity. For inductive loads such as motors or compressors, verify compatibility and consider protective devices or contactors if required. Periodically check mechanical trippers and the dial for wear or displacement and perform wiring inspections during routine maintenance.
