5. Instruccions de funcionament
This section provides general guidance on operating your H-Tronic 110990 TDR 2004. Specific menu navigation and parameter settings may vary; refer to the detailed programming guide (if supplied separately) for advanced configurations.
5.1 Engegada inicial
- After ensuring all connections are secure, apply power to the device.
- The display should illuminate, showing current temperature readings or a startup sequence.
5.2 Setting Temperature Parameters
The TDR 2004 is a differential temperature controller, meaning it controls based on the temperature difference between two points (e.g., collector and storage tank in a solar thermal system).
- Differential ON (ΔT_ON): This parameter sets the temperature difference at which the relay will switch ON (e.g., pump starts).
- Differential OFF (ΔT_OFF): This parameter sets the temperature difference at which the relay will switch OFF (e.g., pump stops).
- Maximum Temperature (T_MAX): An upper limit for one of the sensors, often used for safety or to prevent overheating.
- Minimum Temperature (T_MIN): A lower limit for one of the sensors, often used for frost protection.
Use the navigation buttons (usually UP, DOWN, SET/MENU) on the device to access and adjust these parameters. Consult the device's display and button layout for specific instructions.
5.3 Seguiment
The display typically shows the current temperatures from the connected sensors and the status of the relay output (ON/OFF).
6. Manteniment
The H-Tronic 110990 TDR 2004 is designed for low maintenance. Regular checks can help ensure its longevity and reliable operation.
- Neteja: Netegeu periòdicament l'exterior del dispositiu amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents.
- Connexions: Comproveu anualment totes les connexions elèctriques per comprovar si estan ben ajustades i si hi ha signes de corrosió.
- Ventilació: Assegureu-vos que les obertures de ventilació no estiguin obstruïdes per evitar el sobreescalfament.
- Comprovació del sensor: Periodically verify the accuracy of your temperature sensors if possible, or check for physical damage to the sensor cables.
ADVERTIMENT: Desconnecteu sempre l'alimentació abans de realitzar qualsevol manteniment.
