4. Setup
4.1 Installation
The THC15A timer switch is designed for DIN rail mounting. Follow these steps for installation:
- Disconnect Power: Ensure the main power supply to the installation area is completely switched off before proceeding.
- Mounting: Clip the timer switch onto a standard 35mm DIN rail within your electrical panel.
- Wiring: Refer to the wiring diagram on the back of the device (Figure 4) and the instructions below for correct connections.
- Power Input (220V AC): Connect the Live (L) wire to terminal 1 and the Neutral (N) wire to terminal 2.
- Load Output: Connect the Live wire from the load to terminal 4 (Common). Connect the Live wire to be switched to terminal 3 (Normally Open, NO) for standard operation (power ON when timer is active). If a Normally Closed (NC) connection is required, use terminal 5.
- Bridging: For typical applications, a bridge wire is required between terminal 1 (Input Live) and terminal 4 (Output Common) if the load is to be powered by the same source as the timer.
- Secure Connections: Ensure all wire connections are tight and secure.
- Restore Power: Once installation is complete and verified, restore the main power supply.
4.2 Initial Power-Up and Reset
Upon initial power-up or after a prolonged power outage, the display may be blank. The internal battery will charge, and the display should activate within a few minutes. If the display remains blank or shows erratic characters, perform a reset:
- Locate the small RESET button on the front panel (usually recessed).
- Use a pointed non-metallic object (e.g., a pen tip) to press the RESET button.
- The display will clear, and the timer will return to its default settings (00:00, Monday).
5. Operating Instructions
5.1 Setting Current Time and Day
Before programming, set the current time and day:
- Press and hold the CLOCK button (often marked with a clock icon).
- While holding CLOCK, press D+ to set the current day (MO, TU, WE, TH, FR, SA, SU).
- While holding CLOCK, press H+ to set the current hour (0-23).
- While holding CLOCK, press M+ to set the current minute (0-59).
- Release the CLOCK button. The time is now set.
5.2 Programming ON/OFF Cycles
The timer allows up to 17 ON/OFF programs. Follow these steps:
- Press the P button (Program). The display will show '1 ON'.
- Press D+ to select the day(s) for this program. You can choose individual days, blocks of days (e.g., MO-FR, SA-SU), or all days (MO-SU).
- Press H+ to set the desired ON hour.
- Press M+ to set the desired ON minute.
- Press P again. The display will show '1 OFF'.
- Repeat steps 2-4 to set the OFF time for the first program.
- Press P again to move to the next program ('2 ON'). Repeat the process for all desired programs (up to 17 ON/OFF pairs).
- To exit programming mode, press the CLOCK button. The timer will return to displaying the current time.
5.3 Manual Override
The MANUAL button allows you to temporarily override the programmed settings:
- Press MANUAL repeatedly to cycle through modes:
- AUTO ON: The output is currently ON, but will follow the next programmed OFF event.
- AUTO OFF: The output is currently OFF, but will follow the next programmed ON event.
- ON: The output is forced ON, ignoring all programs.
- OFF: The output is forced OFF, ignoring all programs.
- To return to automatic operation, cycle through the modes until 'AUTO ON' or 'AUTO OFF' is displayed, depending on the current programmed state.
6. Maintenance
The POPP THC15A Digital Programmable Weekly Timer Switch requires minimal maintenance. Keep the device clean and free from dust. Do not use abrasive cleaners or solvents. Ensure the ventilation slots (if any) are not obstructed. The internal battery is designed for long-term use and is not user-replaceable.
7. Troubleshooting
If you encounter issues with your timer switch, refer to the table below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power supply; internal battery discharged. | Check power connections. Allow time for internal battery to charge (up to 15 minutes). If still blank, perform a reset. |
| Timer not switching load ON/OFF. | Incorrect wiring; program error; manual override active; load exceeds capacity. | Verify wiring according to Figure 4. Check programmed ON/OFF times. Ensure timer is in 'AUTO' mode. Confirm load does not exceed 16A/3500W. |
| Time is inaccurate. | Initial setting error; significant power fluctuations. | Reset and re-set the current time and day. The device has automatic error correction of +/- 30 seconds weekly. |
| Cannot enter programming mode. | Buttons unresponsive; device malfunction. | Perform a reset. If the issue persists, contact customer support. |
