2. Key Features
The Theben SYN 161d Analog Timer offers a range of features designed for precise and reliable time control:
- Analog Timer: Simple and intuitive analog interface for setting daily programs.
- 1 Channel: Controls a single circuit.
- Daily Program: Allows for repetitive switching cycles over a 24-hour period.
- 96 Switching Segments: Enables precise programming with a shortest switching time of 15 minutes.
- Network Synchronization: Ensures accurate timekeeping by synchronizing with the power grid frequency.
- 12h/24h Display: Clear time display with hands and 12h/24h detection.
- Easy Time Correction: Simple adjustment for daylight saving time (summer/winter time) and counter-clockwise time correction.
- DuoFix Spring Terminals: Facilitates quick and secure connection for up to two conductors (0.5 to 2.5 mm² wire diameter).
- Manual Switch: Three-position switch for continuous ON, AUTO (programmed operation), or continuous OFF.

3. Installation and Setup
The Theben SYN 161d timer is designed for DIN rail mounting. Ensure all power is disconnected before proceeding with installation.
3.1 Safety Instructions
- Installation must be performed by a qualified electrician.
- Disconnect power supply before installation or maintenance.
- Observe all local and national electrical codes and regulations.
- Do not operate the device if it is damaged.
3.2 Mounting
The timer is designed for mounting on a standard DIN rail (3 TE width).
- Ensure the DIN rail is securely fastened within the electrical enclosure.
- Align the timer with the DIN rail and press firmly until it clicks into place.
3.3 Wiring
The SYN 161d uses DuoFix spring terminals for secure wiring. These terminals are suitable for solid or stranded wires (with or without ferrules) with a diameter of 0.5 to 2.5 mm².
- Identify the terminals: L (Line/Phase), N (Neutral), and the switching contacts (1, 2, 3).
- Press the release button on the DuoFix terminal to open the connection.
- Insert the stripped wire into the terminal.
- Release the button to secure the wire. Gently pull on the wire to ensure a firm connection.
- Connect the power supply (230V AC, 50Hz) to the L and N terminals.
- Connect the load to the switching contacts (e.g., L to terminal 1, load to terminal 2, and terminal 3 for changeover if needed). Refer to the wiring diagram on the device for specific connections.

4. Operation
4.1 Setting the Current Time
Rotate the central dial clockwise until the current time aligns with the time marker (usually a small arrow or line on the casing). The dial has 24-hour markings.
Figure 4: Setting dial for time adjustment.
4.2 Programming Switching Times
The outer ring of the dial consists of 96 segments, each representing 15 minutes. To program a switching time:
- For ON periods: Push the segments outwards for the desired duration.
- For OFF periods: Leave the segments pushed inwards.
- Each pushed-out segment will activate the circuit during its corresponding 15-minute interval.
4.3 Manual Override Switch
The manual override switch allows you to temporarily change the timer's state, regardless of the programmed settings. It has three positions:
- Continuous ON (I): The circuit remains continuously active.
- AUTO (Clock symbol): The timer operates according to the programmed switching times.
- Continuous OFF (0): The circuit remains continuously inactive.

5. Maintenance
The Theben SYN 161d Analog Timer is designed for long-term, maintenance-free operation. However, periodic checks can ensure optimal performance.
- Cleaning: Use a dry, soft cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
- Connection Check: Periodically check the wiring connections to ensure they remain secure. (Ensure power is disconnected before checking connections).
- Environmental Conditions: Ensure the timer is operated within its specified temperature and humidity ranges to prevent damage.
