## Summary description

Thermostatic sensor Danfoss RA 015G3390 is a radiator-mounted temperature sensor designed for use with heating radiators and thermostatic valves. It provides temperature sensing for automatic regulation of room temperature, enabling stable thermal control in residential or commercial heating systems. Suitable for integrating with compatible Danfoss radiator valves to optimize comfort and energy use.

## Long description

Thermostatic sensor Danfoss RA 015G3390 for radiator temperature control is a radiator-mounted temperature sensor designed to work with compatible thermostatic radiator valves. It senses ambient room temperature at the radiator and transmits thermal information to the valve, enabling automatic modulation of hot water flow through the radiator. The unit is intended for use in residential and commercial heating systems where a compact, reliable sensing element is required to maintain stable indoor temperatures and improve energy efficiency.
Advantages
The Danfoss thermostatic sensor provides accurate temperature feedback to radiator valves for consistent room-level control. Its compact form factor and simple mounting make installation straightforward on most standard radiators. The sensor is manufactured to industry quality standards to ensure reliable long-term performance and compatibility with Danfoss valve bodies and actuator systems. Using a dedicated radiator-mounted sensor helps reduce temperature fluctuations and supports more efficient heating operation.
Suitable for
Automatic temperature control in residential radiators
Commercial and office heating systems using thermostatic radiator valves
Retrofit projects to upgrade manual valves to thermostatic control
Applications where localized, radiator-level temperature sensing is required
Key specifications
Mounting: radiator-mounted sensor designed for direct integration with thermostatic valves
Function: ambient temperature sensing for automatic valve control
Compatibility: intended for use with compatible Danfoss radiator valve bodies and actuators
Design: compact sensor housing suitable for standard radiator installations
Application environment: indoor heating systems in residential and commercial buildings
How to use
Mount the thermostatic sensor directly on the radiator in accordance with the radiator valve manufacturer’s instructions and the installation environment. Ensure the sensor is positioned where it can accurately measure room air temperature and is not obstructed by furniture, curtains, or other heat sources. Connect or fit the sensor to the compatible Danfoss valve or actuator as specified, then commission the heating system and verify that the valve responds to temperature changes. Periodic visual inspection is recommended to confirm the sensor remains securely mounted and unobstructed.
Usage recommendations
Place the sensor on a section of the radiator away from direct drafts, sunlight, or local heat sources to ensure representative room temperature readings. For optimal system performance, use the sensor together with compatible Danfoss thermostatic valves and follow commissioning procedures to balance the heating system.
