## Summary description

Thermostatic radiator valve head Herz MINI with a setpoint range of 16–28 °C for temperature control on radiator valves. Designed to replace or upgrade manual valve heads, it enables automatic regulation of room temperature by sensing ambient temperature and adjusting flow through the valve. Suitable for residential and commercial heating systems requiring basic thermostatic control and room-level temperature stabilization.

## Long description

The Herz MINI thermostatic radiator valve head provides basic room temperature control with a setpoint range of 16–28 °C. Designed for installation on compatible radiator valves, this compact valve head senses ambient temperature and modulates the valve position to maintain the selected setting. It is intended as a direct replacement for manual valve heads or as an upgrade to enable automatic temperature regulation in residential and light commercial heating systems.
Advantages
The compact design of the Herz MINI valve head allows installation in confined spaces and on a variety of radiator valve bodies. Its simple temperature scale and mechanical sensing element offer reliable, maintenance-free operation for standard heating applications. By regulating flow according to room temperature, the device helps stabilize indoor climate and reduce manual intervention compared with non‑thermostatic valve heads.
Suitable for
Standard domestic radiators where basic thermostatic control is required
Small commercial or office radiators with manual valve replacement needs
Retrofit projects to convert manual valves into automatic temperature-regulating valves
Key specifications
Setpoint temperature range: 16–28 °C
Type: mechanical thermostatic radiator valve head
Design: compact form suitable for limited installation space
Control method: ambient temperature sensing with proportional modulation of valve position
Mounting: designed for direct attachment to compatible radiator valve bodies
How to use
Fit the Herz MINI valve head onto a compatible radiator valve according to the valve manufacturer’s mounting instructions. Rotate the selector to the desired temperature setting within the 16–28 °C range; the internal sensing element will react to room temperature and adjust the valve position automatically to maintain the selected setpoint. Periodically check that the valve head is securely mounted and free of obstructions that could impair temperature sensing.
Usage recommendations
For accurate room temperature control, avoid placing the valve head behind curtains, furniture, or other objects that block airflow. Use the Herz MINI in rooms where straightforward, maintenance‑free thermostatic control is sufficient; for precise programmability or remote control, consider compatible electronic controllers or smart thermostatic solutions.
