- Press the timer firmly onto the rail until it clicks into place.
5.2 Wiring
Refer to the wiring diagram on the device and below for correct connections. Incorrect wiring can damage the device or cause electrical hazards.
Image 5.1: Side view of the TM626 showing the wiring terminals and a simplified internal diagram. Terminals A1 and A2 are for power input (AC220V). Terminals 15, 16, 18 are for load output (15: Common, 16: Normally Closed, 18: Normally Open).
- Connect the AC220V power supply to terminals A1 and A2.
- Connect the common wire of your load to terminal 15.
- For normally open operation (load turns ON when timer activates), connect the load's live wire to terminal 18.
- For normally closed operation (load turns OFF when timer activates), connect the load's live wire to terminal 16.
- Ensure all connections are secure and insulated.
5.3 Initial Power-Up
After wiring, restore power. The display should light up. If the display is blank, check power connections. The timer may require an initial charge if it has been stored for a long time; allow it to be powered for a few minutes.
6. Operating Instructions
The TM626 timer switch allows you to set the current time and program multiple on/off cycles.
6.1 Setting Current Time and Day
- Press the CLOCK button (if available, or a similar button for time setting).
- Use the D+ (Day), H+ (Hour), and M+ (Minute) buttons to adjust the current day, hour, and minute.
- Press CLOCK again to save and exit.
6.2 Programming On/Off Cycles
The TM626 typically supports multiple ON/OFF programs. The exact number may vary, but common models support 8-16 programs.
- Press the PROG button. The display will show "1 ON".
- Use D+ to select the day(s) for this ON event (e.g., Mon-Fri, Sat-Sun, every day, specific days).
- Use H+ and M+ to set the desired ON time.
- Press PROG again. The display will show "1 OFF".
- Use D+, H+, and M+ to set the desired OFF time for the first program.
- Repeat steps 1-5 for additional ON/OFF programs (e.g., "2 ON", "2 OFF", etc.).
- After setting all desired programs, press the CLOCK button to exit programming mode and save settings.
6.3 Manual Override
The MANUAL or ON/AUTO/OFF button allows you to manually override the programmed settings.
- Pressing this button cycles through modes: ON (always on), AUTO (follows programs), OFF (always off).
- Select AUTO for the timer to execute its programmed schedules.
6.4 Reset Function
To clear all settings and return the timer to its factory default state, locate the small RESET button (often recessed) and press it using a pointed object (e.g., a pen tip). This will erase all time and program settings.
7. Maintenance
The Fafeicy TM626 timer switch requires minimal maintenance to ensure long-term reliable operation.
- Cleaning: Use a soft, dry cloth to wipe the exterior of the device. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage.
- Battery Backup: The device typically includes an internal battery for retaining settings during power outages. This battery is usually non-replaceable by the user and recharges when the device is powered.
8. Troubleshooting
If you encounter issues with your TM626 timer switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power supply; internal battery discharged. | Check power connections to A1/A2. Allow device to be powered for several minutes to charge the internal battery. |
| Load does not turn ON/OFF as programmed. | Incorrect programming; timer in manual ON/OFF mode; incorrect wiring; faulty load. | Verify program settings. Ensure the timer is in AUTO mode. Check wiring connections (15, 16, 18). Test the load independently. |
| Time is incorrect. | Time not set correctly; power interruption (though internal battery should prevent this). | Reset and re-set the current time and day. Ensure the internal battery is charged. |
| Buttons are unresponsive. | Device malfunction; temporary software glitch. | Perform a full reset using the recessed RESET button. If the issue persists, contact support. |
