• Qari tat-Temperatura Mhux Preċiż: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources. Verify that the air vents on the unit are not blocked.
• Sistema ta' Tisħin/Tkessiħ Mhux Qed Tattiva: Check the thermostat's mode (heating/cooling) and set temperature. Ensure the system's circuit breaker is on. Verify wiring connections.
• Display Illegibility: While the display is backlit, some users have reported challenges with readability under certain conditions. Ensure adequate ambient lighting.
• Battery Indicator Always On (with rechargeable batteries): Rechargeable batteries often have a slightly lower voltage (e.g., 1.2V) compared to alkaline batteries (1.5V). This lower voltage may cause the low battery indicator to remain active even when the batteries are fully charged. This is a characteristic behavior and does not necessarily indicate a fault.
