2. Important Safety Instructions
Please read all safety instructions carefully before use. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Electrical Compatibility: This timer is designed for Schuko type sockets (Type F) with a recessed ground contact. It is not compatible with sockets that use a protruding earth pin (e.g., Type E common in France, Belgium, and Poland) unless an appropriate, certified adapter is used. Verify your wall socket type before plugging in the timer.
- Indoor Use Only: This device is intended for indoor use in dry locations only. Do not expose to rain, moisture, or extreme temperatures outside the specified operating range (-40°C to 55°C).
- Voltage and Load: Ensure the connected appliance's voltage and current draw do not exceed the timer's maximum ratings (230V AC, 16A). Overloading can cause overheating and fire.
- Do Not Disassemble: Do not attempt to open or modify the timer. There are no user-serviceable parts inside. Unauthorized modifications will void the warranty and may pose a safety hazard.
- Children and Pets: Keep the timer out of reach of children and pets.
- Unplug Before Cleaning: Always unplug the timer from the wall socket before cleaning.
3. Product Components
Familiarize yourself with the main parts of your Theben Timer 26:
- Time Dial: The large rotating ring with 24-hour markings (0-24).
- Programmable Segments: The blue tabs around the time dial. Each tab represents 15 minutes. Pushing a tab inwards activates the power during that 15-minute interval.
- Current Time Indicator: A small arrow or mark on the stationary part of the timer, indicating the current time on the rotating dial.
- Manual Override Switch: A small switch, typically on the side or top, allowing you to manually turn the connected appliance ON or OFF, overriding the programmed schedule until the next scheduled change.
- Schuko Socket: The central socket where you plug in your appliance.
- Schuko Plug: The plug on the back of the timer that connects to your wall socket.

4. Setup Instructions
Follow these steps to set up your Theben Timer 26:
- Unpack the Timer: Carefully remove the timer from its packaging.
- Check Socket Compatibility: Ensure your wall socket is a compatible Schuko type (Type F). If unsure, consult a qualified electrician.
- Set Current Time: Rotate the entire time dial clockwise until the current time aligns with the stationary current time indicator. For example, if it's 3 PM, align '15' with the indicator.
- Plug into Wall Socket: Insert the timer's Schuko plug firmly into a suitable wall socket.
- Connect Appliance: Plug the appliance you wish to control into the Schuko socket on the front of the timer. Ensure the appliance is switched ON if it has its own power switch.

5. Operating Instructions
5.1. Programming the Daily Schedule
The Theben Timer 26 operates on a 24-hour cycle. Each blue segment around the dial represents a 15-minute interval. To program your desired ON/OFF times:
- Identify ON/OFF Periods: Determine the specific times you want your appliance to be powered ON or OFF.
- Push Segments Inwards for ON: For each 15-minute interval you want the appliance to be ON, push the corresponding blue segment inwards towards the center of the dial.
- Leave Segments Outwards for OFF: For each 15-minute interval you want the appliance to be OFF, leave the corresponding blue segment in its outward position.
The timer will automatically cycle through the 24-hour program, switching the connected appliance according to the pushed-in segments.

5.2. Manual Override
The timer includes a manual override switch, typically located on the side or top. This switch allows you to temporarily bypass the programmed schedule.
- Position 'I' (ON): The appliance will remain continuously ON, regardless of the programmed segments.
- Position '0' (OFF): The appliance will remain continuously OFF, regardless of the programmed segments.
- Timer Symbol Position: The timer will operate according to the programmed schedule.
Moving the switch to 'I' or '0' will override the program until you manually switch it back to the timer symbol position, or until the next scheduled ON/OFF event, depending on the specific model's design. For the Theben Timer 26, the manual override typically holds its position until manually changed back.

6. Maintenance
The Theben Timer 26 requires minimal maintenance.
- Cleaning: Disconnect the timer from the wall socket before cleaning. Wipe the exterior with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the device.
- Storage: If storing the timer for an extended period, ensure it is clean and dry. Store in a cool, dry place away from direct sunlight.
7. Troubleshooting
If you encounter issues with your Theben Timer 26, refer to the following common problems and solutions:
- Appliance does not turn ON/OFF at programmed times:
- Check Manual Override: Ensure the manual override switch is set to the timer symbol position, not 'I' (ON) or '0' (OFF).
- Verify Segments: Confirm that the correct blue segments are pushed inwards for the desired ON times and outwards for OFF times.
- Current Time Setting: Ensure the time dial is set to the correct current time.
- Appliance Power: Check if the connected appliance is switched ON (if it has its own power switch) and functioning correctly when plugged directly into a wall socket.
- Timer is not receiving power:
- Wall Socket: Check if the wall socket is live by plugging in another appliance.
- Timer Plug: Ensure the timer's plug is fully inserted into the wall socket.
- Timer is making unusual noises:
- A faint ticking sound is normal for analog timers. If the noise is loud, grinding, or unusual, discontinue use and contact support.
If these steps do not resolve the issue, please contact Theben customer support.
