8. Vianmääritys
If you experience issues with your thermostat, consult the table below for common problems and solutions. For problems not listed or if solutions do not resolve the issue, contact qualified service personnel.
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Näyttö on tyhjä. | Ei virtalähdettä; sisäinen akku tyhjentynyt. | Check circuit breaker. If power is present, internal battery may need replacement (professional service recommended). |
| Termostaatti ei ohjaa lämmitystä/jäähdytystä. | Incorrect wiring; wrong operating mode; setpoint not reached. | Verify wiring (power off first). Check operating mode (e.g., AUTO, Manual). Adjust setpoint to be above/below current room temperature. |
