5. Operating Instructions
- Program ON/OFF Periods:
The dial is divided into 15-minute segments. To set a period when the appliance should be ON, push down the corresponding segments around the dial. To set a period when the appliance should be OFF, leave the segments in the up position. You can set up to 48 ON/OFF cycles per day.
Example: To turn an appliance ON from 7:00 AM to 8:00 AM, push down the segments from 7 to 8 on the dial.
- Connect the Appliance: Plug the electrical appliance you wish to control into the power socket on the front of the timer. Ensure the appliance's own power switch is set to the ON position.
- Manual Override:
The timer includes a lateral switch. This switch allows you to manually override the programmed settings:
- Set to "ON": The appliance will remain continuously ON, regardless of the dial settings.
- Set to "TIMER": The appliance will operate according to the programmed ON/OFF cycles.
6. Maintenance
- Clean the timer with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Store the timer in a cool, dry place when not in use.
- Regularly check the timer and its connections for any signs of damage.
7. Troubleshooting
- Appliance does not turn ON/OFF at programmed times:
- Check if the timer is correctly plugged into the wall socket.
- Verify that the current time is accurately set on the dial.
- Ensure the correct segments are pushed down for the desired ON periods.
- Confirm the manual override switch is set to "TIMER".
- Check if the connected appliance's power switch is in the ON position.
- Ensure the appliance is functioning correctly when plugged directly into a wall socket.
- Timer is not rotating:
- Ensure the timer is plugged into a live wall socket.
- The timer is mechanical and relies on the mains power to operate its internal clock. If the power is interrupted, the time setting may become inaccurate.
