Thermostatic Radiator Head DANFOSS Aero RA click with built-in sensor, MIN 16°

Thermostatic radiator head DANFOSS Aero RA click with built-in sensor, MIN 16° provides direct local temperature control for radiators. The integrated temperature sensor measures ambient temperature close to the valve and adjusts the valve position to maintain the selected setpoint. The device is designed for use on compatible radiator valves and supports automatic regulation to improve comfort and manage energy consumption in residential and commercial heating systems.

Advantages

The Aero RA click head offers a compact design with simple mechanical adjustment and a clear minimum setting of 16°, which prevents overcooling in rooms that require a baseline temperature. Built-in sensing eliminates the need for remote sensors, ensuring responsive control at the radiator. The click mounting simplifies installation and removal for maintenance or replacement, while the mechanical operation ensures reliable performance without wiring or external power.

Suitable for

• Individual room temperature control in apartments and houses
• Temperature regulation in offices and commercial spaces with compatible radiator valves
• Upgrading old thermostatic valves to a model with a clear minimum temperature limit
• Applications where local sensing at the radiator is preferred over remote sensors

Key specifications

• Built-in ambient temperature sensor for local measurement
• Minimum temperature setting: 16° (predefined MIN position)
• Mechanical thermostatic operation, no electrical supply required
• Click-fit mounting for straightforward attachment to compatible valves
• Compact form factor suitable for standard radiator valve positions

How to use

Mount the thermostatic head onto a compatible radiator valve using the click-fit mechanism. Rotate the control head to select the desired setpoint; use the MIN 16° position to maintain a baseline room temperature of approximately 16 degrees Celsius. The built-in sensor will detect ambient temperature near the valve and modulate valve flow automatically to reach and hold the selected temperature. No wiring is required—operation is fully mechanical. For initial setup, allow the room to stabilize for a few hours after adjustment to confirm the selected setpoint is achieved.

Usage recommendations

Install the head on valves that match the manufacturer’s compatibility list and avoid mounting where direct sunlight or localized heat sources (radiators, heaters, lamps) can affect the built-in sensor. For balanced system performance, combine individual thermostatic heads with appropriate radiator balancing and central boiler control settings. Periodically check the click connection and ensure the head can rotate freely for correct sensing and modulation.
