Introduction
The Danfoss RAW 5012 013G5012 Thermostatic Head with Remote Sensor is designed to provide precise and efficient temperature control for your heating system. This device is compatible with all RA 2000 series valve bodies and integrated radiator valves. It features a built-in limiter and lockable settings, allowing for customized temperature management. The remote sensor, with a capillary length of 0-2 meters, enables accurate temperature measurement away from the radiator, ensuring optimal comfort in the room. This manual provides essential information for the safe installation, operation, and maintenance of your thermostatic head.
Safety Information
- Read all instructions carefully before installation and use.
- Ensure the heating system is depressurized and cooled before attempting any installation or maintenance.
- Installation should be performed by a qualified professional if you are unsure about any steps.
- Do not attempt to modify the device. Unauthorized modifications may void the warranty and pose safety risks.
- Keep the device out of reach of children.
Product Overview
The Danfoss RAW 5012 013G5012 thermostatic head consists of a main control unit with a temperature dial and a remote sensor connected by a capillary tube. The main unit attaches to the radiator valve body, while the remote sensor can be positioned in a location that best reflects the room's ambient temperature.

Installation
The Danfoss RAW 5012 013G5012 thermostatic head is designed for easy installation on Danfoss RA 2000 series valve bodies and integrated radiator valves. Ensure the valve body is clean and free from debris before installation.
Compatibility Check

Mounting the Thermostatic Head
- Ensure the radiator valve is in the fully open position (if adjustable).
- Align the thermostatic head with the valve body. The head typically has a snap-on or screw connection.
- Push the thermostatic head firmly onto the valve body until it clicks into place, or screw it on securely by hand. Do not overtighten.
- Position the remote sensor in an area that accurately reflects the room temperature, away from direct heat sources (like the radiator itself) or drafts. The capillary tube can be routed discreetly.

Operating Instructions
The Danfoss RAW 5012 013G5012 thermostatic head allows you to set your desired room temperature within a range of 8°C to 28°C.
Setting the Temperature
- Rotate the temperature dial on the thermostatic head to your desired setting. The numbers on the dial correspond to temperature levels.
- Typically, '1' represents the lowest setting (around 8°C, often used for frost protection), and '5' represents the highest setting (around 28°C). The '3' setting is generally considered a comfortable room temperature (around 20°C).
- The remote sensor will measure the ambient temperature and adjust the radiator's heat output accordingly to maintain the set temperature.
Using the Limiter and Lockable Settings
The thermostatic head includes a limiter and lockable settings to prevent unauthorized or accidental changes to the temperature range. Refer to the specific instructions provided with your valve body or contact Danfoss support for details on how to engage and disengage these features.
Maintenance
The Danfoss RAW 5012 013G5012 thermostatic head requires minimal maintenance to ensure optimal performance.
- Cleaning: Wipe the thermostatic head and remote sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the surface.
- Inspection: Periodically check the capillary tube for any signs of damage or kinks. Ensure the remote sensor is not obstructed, as this can affect temperature readings.
- Seasonal Check: Before the heating season begins, ensure the thermostatic head moves freely and the temperature dial can be rotated without excessive force.
Troubleshooting
If you experience issues with your thermostatic head, consider the following common problems and solutions:
- Radiator not heating or heating insufficiently:
- Ensure the thermostatic head is set to a temperature higher than the current room temperature.
- Check if the remote sensor is obstructed or placed in a cold draft. Relocate if necessary.
- Verify that the valve pin is not stuck. Gently press the pin on the valve body (after removing the thermostatic head) to ensure it moves freely.
- Bleed the radiator to remove any trapped air.
- Room is too hot:
- Lower the temperature setting on the thermostatic head.
- Ensure the remote sensor is not exposed to direct sunlight or other heat sources. Relocate if necessary.
- Thermostatic head is loose:
- Re-secure the thermostatic head to the valve body, ensuring it is properly clicked or screwed into place.
If these steps do not resolve the issue, contact Danfoss customer support or a qualified heating technician.
