1. Prodott Aktarview
The Danfoss Aveo™ 015G4290 is a premium-quality, non-electric thermostatic operator designed for mounting onto Danfoss RA radiator valves. This device utilizes unique gas-filled technology to provide fast and precise temperature control, helping to regulate individual room temperatures by modulating the supply of hot water or low-pressure steam through the radiator. Its streamlined design is suitable for various heating systems and applications, particularly those requiring a small P-band (1K) for optimal performance.
Il-karatteristiċi ewlenin jinkludu:
- Gas-filled Technology: Offers the world's fastest reacting self-acting thermostat, providing up to 2% additional energy savings compared to conventional liquid bellows.
- Installazzjoni mingħajr sforz: Features a unique click-connection system that requires no tools. Simply click and turn for immediate operation without calibration or adjustments.
- Intuitive Temperature Control: A valve-mounted thermostatic sensor with a tactile dial allows for precise temperature setting, with each click corresponding to a 1 °F increment.
- Protezzjoni mill-ġlata: Includes a frost stat setting to prevent pipes from freezing when the room temperature drops too low.
2. Informazzjoni dwar is-Sigurtà

4. Installazzjoni (Setup)
The Danfoss Aveo™ 015G4290 thermostatic operator is designed for easy, tool-free installation onto existing Danfoss RA radiator valves.
- Ipprepara l-Valv: Ensure the existing radiator valve is clean and free from debris. If replacing an old operator, remove it by unscrewing or unclipping it from the valve body.
- Align the Operator: Position the Aveo™ operator over the Danfoss RA valve. The connection type is RA-click, designed for a secure fit.
- Click and Turn: Push the operator onto the valve until you hear a distinct 'click'. Then, turn the operator clockwise until it is firmly seated. No additional tools or calibration are required. The thermostatic operator will begin functioning immediately.

5. Operazzjoni
The Danfoss Aveo™ operator allows for precise and intuitive temperature control within a room.

Immaġni 5.1: Mill-qrib view of the Danfoss Aveo™ operator's dial, showing temperature settings from 1 to 5 and the frost protection symbol.
- Aġġusta tat-Temperatura: Rotate the dial on the operator to select your desired room temperature. The dial features tactile feedback, with each click representing approximately a 1 °F change in the set temperature.
- Skala tat-Temperatura: The dial typically features numerical settings from 1 to 5, corresponding to a temperature range of approximately 45 °F to 82 °F. Consult the table below for approximate temperature equivalents.
- Protezzjoni mill-ġlata: Turn the dial to the '*' (snowflake) symbol for frost protection. In this setting, the valve will open only if the room temperature drops below approximately 45 °F (7 °C) to prevent freezing.

6. Manutenzjoni
The Danfoss Aveo™ 015G4290 thermostatic operator is designed for minimal maintenance.
- Tindif: Wipe the exterior of the operator with a soft, damp drapp. Tużax prodotti tat-tindif jew solventi li joborxu, għax dawn jistgħu jagħmlu ħsara lill-finitura.
- No Calibration Required: The gas-filled sensor does not require periodic calibration or adjustments after initial installation.
- Spezzjoni: Periodically check for any signs of damage or loose connections. If any issues are observed, refer to the troubleshooting section or contact support.
7 Issolvi l-problemi
If you encounter issues with your Danfoss Aveo™ thermostatic operator, refer to the following common problems and solutions:
- Ir-Radjatur Mhux qed Jissaħħan:
- Ensure the dial is set to a temperature higher than the current room temperature.
- Check that the operator is securely attached to the radiator valve. A loose connection can prevent proper operation.
- Verify that the main heating system is operational and supplying hot water to the radiator.
- Room is Too Hot/Cold (despite setting):
- Confirm the operator is not obstructed by curtains, furniture, or other objects that could interfere with its ability to sense room temperature accurately.
- Ensure the operator is not exposed to direct sunlight or drafts, which can affect its temperature readings.
- Adjust the dial incrementally to find the optimal setting for your comfort.
- Difficulty Turning the Dial:
- The dial should turn smoothly with tactile clicks. If it feels stiff, check for any physical obstructions.
- Do not force the dial. If resistance persists, the internal mechanism may be damaged, and the unit may need replacement.
If these steps do not resolve the issue, please contact Danfoss customer support.
