4. Modes de funcionament

The C-LOGIC 420-TC offers several operating modes to suit your needs:

• Mode manual: Allows you to set a constant desired temperature that the system will maintain until changed.
• Mode manual temporal: Overrides the current program for a set period, after which it reverts to the programmed schedule.
• Mode de vacances: Maintains a specific temperature for an extended period (e.g., during a vacation) to save energy while preventing freezing.
• Programes automàtics: The thermostat includes three automatic programs:
  • P1 (Configurable Weekly): Allows you to set a personalized heating/cooling schedule for each day of the week.
  • P2 (Predefined): A factory-set program for typical daily use.
  • P3 (Predefined): Another factory-set program, offering a different schedule.

5. Programming Weekly Schedule (P1)

To configure Program P1, navigate to the programming menu using the thermostat's controls. You will typically be able to set different temperature targets for various time segments throughout each day of the week. Consult the full instruction manual for detailed steps on setting specific time and temperature points for P1.

6. Configuració avançada

The C-LOGIC 420-TC includes several advanced settings for fine-tuning its operation:

• Bloqueig de pantalla: Prevents unintended changes to settings, useful in public areas or homes with children.
• Adjustable Hysteresis (1–9 °C): Controls the temperature differential before the heating/cooling system activates. A smaller hysteresis means more frequent but precise temperature control.
• Compensació de temperatura: Allows for calibration of the displayed temperature if it differs from an external reference.
• Automatic Anti-freeze/Descaling Function: Helps protect your heating system from freezing and reduces scale buildup in valves.

7. Manteniment

7.1 Substitució de la bateria

When the low battery indicator appears on the transmitter's LCD screen, replace the 2 AA batteries promptly to ensure continuous operation. Use high-quality alkaline batteries for best performance.

7.2 Neteja

Wipe the thermostat's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the device.

8. Solució De Problemes

If you encounter issues with your C-LOGIC 420-TC thermostat, consider the following:

• Sense pantalla/alimentació: Check transmitter batteries. Ensure receiver is properly connected to 230V power.
• No Communication (RF Signal Lost): Ensure both units are within range (max 30m indoors). Check for obstructions or interference. Re-pair the units if necessary (refer to section 3.5).
• Lectura de temperatura incorrecta: Verify temperature compensation settings. Ensure the transmitter is not placed near heat sources or drafts.
• El sistema no respon: Check receiver wiring to the boiler. Ensure the boiler itself is operational. Verify the thermostat is in the correct operating mode.

For persistent issues, consult the comprehensive troubleshooting guide in the full product manual or contact customer support.
