6. Maintenance
6.1 Battery Replacement
The THC30A timer includes a built-in CR2032 lithium battery for power-off memory. This battery typically lasts for several years. If the display becomes dim or the time/settings are lost frequently during power outages, the battery may need replacement. Consult a qualified technician for battery replacement.
6.2 Cleaning
Wipe the timer's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing or display.
7. Troubleshooting
- Display is blank: Check power supply. If power is present, the internal battery might be fully discharged; allow time for it to charge. If still blank, press the RESET button.
- Timer not switching ON/OFF as programmed:
- Ensure the timer is in AUTO mode (not ON or OFF via manual override).
- Verify that the current time and day are set correctly.
- Check that the programmed ON/OFF times and days are correct and active.
- Confirm wiring connections are secure and correct.
- Load not receiving power: Check the load device (e.g., bulb, motor) for functionality. Verify input power to the timer. Ensure the timer is in an ON state (either programmed ON or manually ON).
- Settings are lost after power outage: The internal battery may be depleted. Consider replacing the CR2032 battery.
