Thermostatic Radiator Valve Head DANFOSS Redia M30x1.5 with Built-in Sensor, MIN 16°

The DANFOSS Redia M30x1.5 thermostatic radiator valve head with built-in sensor provides local temperature regulation for radiators. It is designed to fit M30x1.5 valve threads and offers a minimum setting angle of 16°, allowing finer control near the lower end of the temperature range. The unit replaces or upgrades existing thermal heads on compatible radiator valves and is suitable for both domestic and light commercial heating systems where individual room regulation is required.

Advantages

The built-in temperature sensor enables accurate measurement of ambient heat near the radiator, reducing the influence of direct heat sources and improving control precision. The compact M30x1.5 mounting ensures straightforward replacement of common thermostatic heads without additional adaptors. The MIN 16° function gives a clearer and more repeatable low-temperature setting to help avoid unnecessary heating and support energy-efficient operation.

Suitable for

• Replacing existing thermostatic heads on radiators with M30x1.5 thread
• Local room temperature control in apartments and houses
• Individual zone regulation in offices and small commercial spaces
• Upgrading manual valves to thermostatic control for improved comfort and energy savings

Key specifications

• Mounting thread: M30x1.5 compatible
• Built-in temperature sensor for local ambient control
• Minimum setting/angle: 16° for precise low-end adjustment
• Type: thermostatic radiator valve head (manual/mechanical thermostatic control)
• Application: hot-water radiator heating systems

How to use

Fit the DANFOSS Redia head onto a compatible radiator valve with M30x1.5 thread following the valve manufacturer's installation guidance. Ensure the valve spindle is in the correct position before mounting the head and tighten by hand or with recommended tools without over-torquing. Set the control to the desired position; the internal sensor will react to room temperature changes and modulate the valve position to maintain the selected level. Periodic visual checks ensure the head operates freely and that furniture or curtains do not obstruct the sensor.

Usage recommendations

Install the thermostatic head at a representative height and location on the radiator to avoid direct sunlight, drafts, or heat sources that could affect sensor accuracy. For best performance, allow a short settling period after installation and avoid covering the radiator or the head with obstructions. If replacing a different thread or adapter type, verify compatibility or use the correct adapter recommended by the valve or head manufacturer.
