Instruccions de muntatge:
- Prepare the Valve Body: Ensure the existing RAVL valve body is clean and free from debris. If replacing an old thermostatic head, remove it carefully.
- Set the Thermostatic Head: Turn the setting dial on the new Aero RAVL head to its maximum setting (usually '5' or '28°C') to fully retract the pin.
- Posicionar el cap: Place the Aero RAVL thermostatic head onto the RAVL valve body. Ensure it is aligned correctly.
- Secure the Mounting Ring: Push the mounting ring firmly onto the valve body until you hear an audible 'click'. This confirms the head is securely attached. No tools are required for this step.
- Verifica la instal·lació: Gently try to rotate the head. It should be firmly attached and not wobble.
Instruccions de funcionament
The Danfoss Aero RAVL valve allows for manual temperature control to maintain your desired room temperature.
Configuració de la temperatura:
- The thermostatic head features a numbered dial (typically 1 to 5, or a temperature scale from 7°C to 28°C).
- Rotate the dial to your desired temperature setting. Each click provides tactile feedback, indicating a 0.5°C change in the set point.
- Setting '❄' (Frost Protection): This setting maintains a minimum temperature (around 7°C) to prevent pipes from freezing.
- Setting '1' (Approx. 14°C): A lower comfort temperature.
- Setting '3' (Approx. 20°C): A common comfort temperature for living areas.
- Setting '5' (Approx. 28°C): Maximum heating.
- The valve will automatically adjust the flow of hot water to the radiator to maintain the selected room temperature.

Manteniment
The Danfoss Aero RAVL thermostatic valve requires minimal maintenance to ensure long-term performance.
- Neteja: Netegeu l'exterior del capçal termostàtic amb un drap suau i sec.amp drap. No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar la superfície.
- Eliminació de pols: Periodically remove any dust accumulation from the valve and radiator to ensure proper air circulation around the integrated sensor.
- Comprovació de la funció: Annually, rotate the dial through its full range of settings to ensure smooth operation and prevent internal components from sticking.
- Evitar obstruccions: Ensure that curtains, furniture, or other objects do not obstruct the thermostatic head, as this can interfere with accurate temperature sensing.
Resolució de problemes
If you experience issues with your thermostatic radiator valve, consult the table below for common problems and solutions.
| Problema | Causa possible | Solució |
|---|---|---|
| Radiator remains cold despite high setting. | Valve pin stuck in closed position; air in the system; system pressure too low. | Remove the thermostatic head and gently press the valve pin several times to free it. Bleed the radiator. Check system pressure and refill if necessary. |
| Room is too cold/hot, inconsistent temperature. | Thermostatic head obstructed; incorrect setting; external heat sources/drafts. | Ensure the head is not covered by curtains or furniture. Adjust the setting. Eliminate drafts or reposition heat-emitting objects. |
| Valve head is loose or falls off. | Mounting ring not fully engaged. | Re-attach the thermostatic head, ensuring the mounting ring clicks securely into place. |
| No tactile feedback when adjusting dial. | Problema de mecanisme intern. | Contact Danfoss support or a qualified technician for inspection. |
