If water hammer is experienced, a patented unique flow selection device within the valve can be turned to reverse the water direction inside the valve without the need to drain down the system. The RAS-C2 sensor, based upon the tried and tested liquid sensor actuator, is compact and provides highly accurate temperature control. Sensor mounting requires no tools, simply press the sensor onto the valve body and hand tighten a clamping ring to secure. The sensor incorporates a frost protection setting and a positive off feature, useful if radiators need to be removed for decoration. RAS-C2 sensors are compatible with RA-FS flow selectable bi-directional valves, RA-FN, RA-N and RA-G valve bodies. Offers frost protection. Positive shut-off. Liquid Sensor.
This guide is for users of the Danfoss RAS-C2 radiator valve, designed for precise temperature control in your home. The RAS-C2 offers frost protection and positive shut-off features. Note that while easy to install, optimal performance relies on correct valve body compatibility.

What is the maximum temperature setting?
The maximum temperature setting is 28°C.
Does it have frost protection?
Yes, the RAS-C2 incorporates a frost protection setting.
Can I remove the radiator for decoration?
Yes, the positive shut-off feature allows you to completely shut off the radiator for maintenance or decoration.
Which valve bodies are compatible?
The RAS-C2 is compatible with RA-FS flow selectable bi-directional valves, RA-FN, RA-N and RA-G valve bodies.
What should I do if my radiator is making a hammering noise?
If using the RA-FS valve body, try reversing the water direction inside the valve using the flow selection device. If the noise persists, consult a qualified heating engineer.
How do I clean the RAS-C2?
Wipe the valve with a damp cloth to remove dust. Avoid using harsh chemicals or abrasive cleaners.
Troubleshooting
Radiator not heating up.
Ensure the valve is open and not in the shut-off position. Check for airlocks in the system and bleed the radiator if necessary. Verify that the system is properly pressurized.
Radiator overheating.
Check the temperature setting on the RAS-C2. Ensure the valve is not blocked or obstructed. Verify the system's balance.
Water hammer noise.
If using the RA-FS valve body, try reversing the water direction inside the valve using the flow selection device. If the noise persists, consult a qualified heating engineer.
