The TM919TK timer switch is designed for DIN rail mounting within an electrical panel. Ensure power is off before proceeding.

6.1 Mounting

1. Locate an available space on a standard 35mm DIN rail within your electrical enclosure.
2. Clip the timer switch onto the DIN rail, ensuring it is securely fastened.

6.2 Wiring

Refer to the wiring diagram below and the labels on the device. Always ensure power is disconnected before making any electrical connections.

• Connect the Neutral (N) wire from your power supply to the 'N' terminal on the timer switch.
• Connect the Live (L) wire from your power supply to the 'L' terminal on the timer switch.
• Connect the Live wire to your load (e.g., light fixture) to the 'LOAD' terminal on the timer switch. The other side of your load should be connected to the Neutral wire.
• Ensure all terminal screws are tightened securely.

6.3 Initial Power-Up

After wiring, restore power to the circuit. The display should illuminate. If the display does not light up, check your wiring and power supply.

7. Initial Configuration

Upon first power-up or after a reset, you will need to configure the basic settings.

7.1 Setting Current Time and Date

1. Press the CLOCK button (often labeled with a clock icon) and hold for 3 seconds to enter time setting mode.
2. Use the HOUR, MINUTE, and DAY buttons to adjust the current time and day of the week.
3. Press CLOCK again to save and exit.

7.2 Setting Time Zone

1. Press the TIME ZONE button (or similar, refer to device specific labels) to cycle through available time zone offsets (+12 to -12).
2. Select your local time zone.

7.3 Setting Latitude and Longitude

These settings are crucial for accurate astronomical calculations.

1. Press and hold the LAT/LONG button (or similar) for 3 seconds to enter setting mode.
2. Use the UP/DOWN arrows to adjust the Latitude (0-70 degrees North/South).
3. Press LAT/LONG again to switch to Longitude setting.
4. Use the UP/DOWN arrows to adjust the Longitude (-180 to 180 degrees).
5. Press LAT/LONG once more to save and exit.

8. Operating Instructions

8.1 Programming ON/OFF Times (Astronomical Mode)

The TM919TK allows for up to 8 ON/OFF programs. These can be set relative to sunrise/sunset or at fixed times.

1. Press the PROG button to enter programming mode. The display will show '1 ON'.
2. Use the HOUR, MINUTE, and DAY buttons to set the desired ON time. To set an astronomical time, press the ASTRO button (or similar) to cycle through options like 'SUNRISE', 'SUNSET', 'SUNRISE + X min', 'SUNSET - X min', etc.
3. Press PROG again to set the '1 OFF' time, repeating the steps above.
4. Continue pressing PROG to set subsequent programs (2 ON, 2 OFF, etc.) up to 8 programs.
5. After setting all desired programs, press the CLOCK button to exit programming mode and return to normal operation.

8.2 Manual Override

To temporarily override the current program state:

• Press the MANUAL button (or similar). The output will switch from ON to OFF or OFF to ON.
• The timer will maintain this manual state until the next programmed event, at which point it will revert to automatic operation.

8.3 12/24 Hour Format Conversion

To switch between 12-hour (AM/PM) and 24-hour formats:

• While in normal time display mode, press the CLOCK button and the HOUR button simultaneously.

8.4 Reset Function

To clear all settings and return the timer to factory defaults:

• Locate the RESET button (often a small recessed button).
• Use a pointed object (e.g., a pen tip) to press the RESET button. The display will clear, and you will need to reconfigure all settings.
