## Summary description

Thermostatic sensor DANFOSS Regus RA 015G3690 is a radiator temperature sensor designed for use in central heating systems. It provides temperature sensing for thermostatic radiator valves and supports stable room temperature control. Suitable for installation on heating radiators to regulate heat output and improve energy efficiency in residential and commercial spaces.

## Long description

Thermostatic Sensor DANFOSS Regus RA 015G3690 is a radiator temperature sensor intended for use with thermostatic radiator valves in central heating systems. The sensor measures ambient temperature near the radiator and transmits the thermal condition to compatible valve bodies, enabling automatic adjustment of heat output. Designed for residential and commercial heating installations, this sensor contributes to stable room temperature control and can help optimize energy consumption when used in a properly configured heating system.
Advantages
The DANFOSS Regus RA sensor provides reliable temperature feedback to thermostatic radiator valves, supporting steady regulation of radiator output. Its compact design allows straightforward mounting on standard radiator valve stems. The sensor is compatible with typical thermostatic valve systems and is manufactured to meet industry expectations for accuracy and durability. By enabling local temperature sensing at the radiator, it helps maintain setpoint temperatures more precisely than relying on a distant room thermostat alone.
Suitable for
Residential radiators in apartments and houses
Commercial heating systems in offices and small businesses
Retrofit projects where thermostatic control is required
Zones requiring independent temperature control per radiator
Key specifications
Type: Thermostatic radiator sensor for use with thermostatic valve bodies
Application: Ambient temperature sensing near radiator
Compatibility: Designed to work with standard thermostatic radiator valve mechanisms
Mounting: Fits typical radiator valve stems for direct temperature feedback
Environment: Indoor use in central heating systems
How to use
Install the thermostatic sensor on the radiator valve stem according to the valve manufacturer's instructions, ensuring a secure mechanical connection and correct orientation for accurate ambient sensing. After mounting, adjust the corresponding thermostatic valve or room setpoint to achieve the desired temperature; the sensor will relay local temperature to the valve mechanism so it can modulate flow. Periodically check the sensor and valve for dust or obstruction that may affect sensing accuracy and verify tightness of the mounting to avoid leaks at the valve connection.
Usage recommendations
Place the sensor on radiators away from direct drafts, heating sources such as nearby convectors or sunlight, and large furniture that could block airflow. For balanced control, use one sensor per radiator and avoid installing the sensor where local effects distort room temperature readings. Follow routine maintenance for the radiator valve and system to ensure continued accurate sensing and efficient operation.
