9. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Timer display is blank | No power supply or internal battery depleted. | Check power connections. If power is present, the internal battery might be fully discharged; allow time for it to charge or consider professional servicing if issues persist. |
| Timer does not respond to button presses | Timer is locked. | Press and hold the MENU button for 3 seconds to unlock. |
| Programs are not executing | Timer is in manual ON/OFF mode, or programs are incorrectly set. | Ensure the timer is in 'ON AUTO' or 'OFF AUTO' mode. Review and correct your programmed ON/OFF times and day selections. |
| Time is inaccurate or resets after power loss | Internal backup battery is weak or depleted. | The internal battery is designed to hold settings for an extended period. If this occurs frequently, the battery may need replacement by a qualified technician. |
10. Käyttäjävinkkejä
- Vara-akku: The timer includes a 3V CR2026 backup battery to maintain settings during power outages. This battery is not rechargeable by the user and is intended for long-term retention of settings.
- Itsenäiset kanavat: The two relay outputs (CH1 and CH2) operate independently. This means you can program different schedules for each channel to control separate devices or circuits.
