Se riscontri problemi con il termostato, fai riferimento ai seguenti passaggi comuni per la risoluzione dei problemi:
- Nessun display/Nessuna alimentazione: Controllare l'alimentazione principale del termostato e assicurarsi che tutti i collegamenti elettrici siano saldi. Verificare che l'interruttore automatico dell'impianto di riscaldamento non sia scattato.
- Lettura errata della temperatura: Ensure the external sensor cable is properly connected and positioned. Avoid placing the thermostat or sensor in direct sunlight or near heat sources that could affect readings.
- Riscaldamento non attivato: Check the set temperature to ensure it is above the current room temperature. Verify that the thermostat is in an active heating mode (not 'OFF' or in a programmed 'OFF' period). Inspect heating elements for functionality.
- Touchscreen che non risponde: Prova a riavviare il termostato spegnendolo e riaccendendolo. Se il problema persiste, contatta l'assistenza clienti.
