5. Installation and Setup

Important: Installation should only be performed by a qualified electrician to ensure safety and compliance with local electrical codes. Disconnect power before installation.

5.1 DIN Rail Mounting

1. Ensure the power supply to the circuit is completely off.
2. Locate a standard 35mm DIN rail within your electrical panel or enclosure.
3. Align the TM616 timer with the DIN rail. The yellow clip on the bottom (refer to Figure 3.3) should engage with the rail.
4. Press the timer firmly onto the DIN rail until it clicks securely into place.

5.2 Wiring Connections

Refer to the wiring diagram on the side of the unit (Figure 3.2) and the specific voltage model (110V, 220V, or 12V) for correct connections. The TM616 typically has terminals for power input (L, N) and load output (NO, NC, COM for relay contacts).

• Connect the incoming Live (L) and Neutral (N) wires to the designated power input terminals of the timer.
• Connect the Live wire from your load (e.g., light, appliance) to the Normally Open (NO) terminal of the timer's relay.
• Connect the Common (COM) terminal of the timer's relay to the Live wire of your power supply.
• Ensure all connections are tight and secure.

Note: The specific wiring configuration may vary slightly depending on whether you are using the Normally Open (NO) or Normally Closed (NC) contact for your application. Always consult the diagram on the device and local electrical standards.

5.3 Initial Power-Up

After wiring, restore power to the circuit. The timer's LCD display should illuminate. If the display is blank, check power connections.

Upon first power-up or after a prolonged power outage, the internal battery may need to charge for a few minutes before full functionality is available. The display might show "OFF" or a default time.

6. Operating Instructions

6.1 Setting Current Time and Day

1. Press the "Clock" button and hold it.
2. While holding "Clock", press "Week" to set the current day of the week (MO, TU, WE, TH, FR, SA, SU).
3. While holding "Clock", press "Hour" to set the current hour.
4. While holding "Clock", press "Minute" to set the current minute.
5. Release the "Clock" button. The time is now set.

6.2 Programming ON/OFF Events (17 Settings)

The TM616 allows for up to 17 ON/OFF program settings. Each program consists of an ON time and an OFF time.

1. Press the "TIMER" button once. The display will show "1 ON" and the time will flash.
2. Press "Week" to select the day(s) for this program (e.g., everyday, weekdays, weekends, specific days).
3. Press "Hour" to set the desired ON hour.
4. Press "Minute" to set the desired ON minute.
5. Press "TIMER" again. The display will show "1 OFF" and the time will flash.
6. Repeat steps 2-4 to set the desired OFF day(s), hour, and minute for this program.
7. Press "TIMER" again to move to the next program setting (e.g., "2 ON"). Repeat the process for up to 17 ON/OFF programs.
8. To exit programming mode and save settings, press the "Clock" button at any time.

Tip: If you need to clear a specific program, press the "C/R" button while viewing that program setting. This will reset the time to "--:--".

6.3 Manual Override

The "Manual" button allows you to override the programmed settings temporarily or permanently.

• Press "Manual" repeatedly to cycle through the modes:
  • ON AUTO: The timer is currently ON and will follow the programmed schedule.
  • OFF AUTO: The timer is currently OFF and will follow the programmed schedule.
  • ON: The timer output is forced ON, overriding all programs.
  • OFF: The timer output is forced OFF, overriding all programs.
• Select "ON AUTO" or "OFF AUTO" to resume normal programmed operation.

7. Maintenance

• Cleaning: Wipe the timer's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery: The internal rechargeable battery is designed for long life and typically does not require replacement. It charges automatically when the timer is connected to power. If the display is consistently blank or loses time rapidly after power outages, the battery may be depleted or at the end of its life.
• Environment: Ensure the timer is installed in a dry environment, free from excessive dust, moisture, and extreme temperatures, within the specified operating range (-20°C to +50°C).
