5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The CH121 thermostat features a user-friendly interface with four main function keys:

• ഓൺ/ഓഫ് ബട്ടൺ: Toggles the thermostat power on or off.
• കംഫർട്ട് ബട്ടൺ: Used to adjust the desired temperature up or down. Pressing this button typically activates the backlight first, then subsequent presses adjust the setting.
• Economy Buttons: These buttons are used to set or activate economy modes, which typically maintain a lower temperature to save energy.

പൊതുവായ പ്രവർത്തനം:

1. Activating the Display: When the display is off (but the thermostat is active), the first press of any button will typically only activate the backlight. Subsequent presses will then perform the button's function.
2. ക്രമീകരണ താപനില: Use the Comfort buttons to increase or decrease the target temperature. The display will show the set temperature temporarily.
3. പ്രതിവാര പ്രോഗ്രാമിംഗ്: Refer to the detailed programming section in the complete manual for instructions on setting weekly schedules for heating and cooling. This allows for automated temperature adjustments throughout the week.
4. താപനില യൂണിറ്റ് തിരഞ്ഞെടുക്കൽ: The thermostat allows you to switch between Celsius (°C) and Fahrenheit (°F) display modes. Consult the full manual for the specific key combination or menu option to change this setting.
5. ബാക്ക്‌ലൈറ്റ് ദൈർഘ്യം: The duration for which the backlight remains active can be adjusted. Refer to the full manual for instructions on customizing this setting.

6. പരിപാലനം

To ensure optimal performance and longevity of your Fantini Cosmi CH121 thermostat, follow these maintenance guidelines:

• ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ: The thermostat is powered by 2 AAA 1.5V alkaline batteries. Replace them when the low battery indicator appears on the display. Always use new, high-quality alkaline batteries.
• വൃത്തിയാക്കൽ: Clean the thermostat's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.
• തടസ്സങ്ങൾ ഒഴിവാക്കുക: കൃത്യമായ താപനില സെൻസിംഗിന് തടസ്സമാകുന്ന ഫർണിച്ചറുകൾ, കർട്ടനുകൾ അല്ലെങ്കിൽ മറ്റ് വസ്തുക്കൾ തെർമോസ്റ്റാറ്റിനെ തടസ്സപ്പെടുത്തുന്നില്ലെന്ന് ഉറപ്പാക്കുക.
• പരിസ്ഥിതി വ്യവസ്ഥകൾ: The maximum ambient temperature for operation is 45 °C. Avoid exposing the thermostat to extreme temperatures or humidity.

7. പ്രശ്‌നപരിഹാരം

If you encounter issues with your CH121 thermostat, consider the following common solutions:

• ഡിസ്പ്ലേ/തെർമോസ്റ്റാറ്റ് പ്രതികരിക്കുന്നില്ല: ബാറ്ററികൾ ശരിയായി ഇൻസ്റ്റാൾ ചെയ്തിട്ടുണ്ടോ എന്നും ആവശ്യത്തിന് ചാർജ് ഉണ്ടോ എന്നും പരിശോധിക്കുക. ആവശ്യമെങ്കിൽ ബാറ്ററികൾ മാറ്റിസ്ഥാപിക്കുക.
• കൃത്യമല്ലാത്ത താപനില വായന: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources. Verify that the air vents on the unit are not blocked.
• Heating/Cooling System Not Activating: 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.
