Setup and Installation
The Danfoss RA/VL2960 thermostatic head is designed for straightforward installation on compatible RA/V valve bodies with a 34 mm neck inner diameter. No special tools are typically required beyond a flat-head screwdriver for the clamping ring connection.
Installation Steps:
- Preparation: Ensure the heating system is depressurized if replacing an old valve or if there is any risk of water leakage. For head replacement only, this may not be necessary, but always exercise caution.
- Remove Old Head (if applicable): If replacing an existing thermostatic head, loosen the clamping ring or connection mechanism that secures it to the valve body. Carefully remove the old head.
- Set New Head: Before mounting, set the new Danfoss RA/VL2960 thermostatic head to its highest setting (typically '5' or 'MAX') to ensure the valve pin is fully retracted. This facilitates easier installation.
- Position and Attach: Place the new thermostatic head onto the valve body, aligning it correctly. The head is designed to fit securely over the valve's neck.
- Secure Connection: Tighten the clamping ring connection firmly using a flat-head screwdriver. Ensure the head is securely fastened and does not wobble. Do not overtighten.
- Verify Operation: Once installed, turn the thermostatic head through its settings to confirm smooth operation and proper engagement with the valve pin.

Operating Instructions
The Danfoss RA/VL2960 thermostatic head allows for manual control of room temperature by regulating the flow of hot water through the radiator. The head features numbered settings, typically from '*' (frost protection) to '5' (maximum heat).
Temperature Control:
- Adjusting Temperature: Rotate the head to the desired setting. Higher numbers correspond to higher room temperatures.
- Frost Protection (*): Setting the head to the '*' symbol activates the frost protection function. This setting ensures the room temperature does not fall below approximately 6-8°C (43-46°F), preventing pipes from freezing.
- Limiting/Locking Settings: The head may have mechanisms to limit the maximum or minimum temperature settings, or to lock it at a specific setting. Refer to the markings on the head for specific instructions on how to engage these features, if present. This is useful for preventing accidental changes or maintaining a consistent temperature.

Maintenance
The Danfoss RA/VL2960 thermostatic head requires minimal maintenance to ensure optimal performance and longevity.
- Cleaning: Periodically wipe the exterior of the thermostatic head with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish.
- Seasonal Check: Before the heating season begins, it is advisable to turn the thermostatic head through its full range of settings a few times. This helps to prevent the valve pin from sticking due to prolonged inactivity.
- Air Circulation: Ensure that the thermostatic head is not obstructed by curtains, furniture, or other objects, as this can interfere with its ability to accurately sense room temperature and regulate heat.
Troubleshooting
If you experience issues with your Danfoss RA/VL2960 thermostatic head, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator remains cold or only partially heats up. |
|
|
| Room is too hot despite low setting. |
|
|
| Head feels loose or wobbly. | Clamping ring not sufficiently tightened. | Tighten the clamping ring connection with a flat-head screwdriver. |
If these steps do not resolve the issue, it may indicate a problem with the valve body itself or the heating system, and professional assistance may be required.
