## Summary description

Thermostatic radiator valve head by Herz, model 1742006, with M28x1.5 thread and integrated surface sensor. Designed to control radiator temperature via a surface-mounted sensing element, it fits valves with M28x1.5 connection. Suitable for residential and commercial heating systems requiring precise room or radiator-level temperature regulation.

## Long description

The Herz thermostatic radiator valve head M28x1.5 with surface sensor (model 1742006) is a compact temperature control actuator designed for use on compatible radiator valves. It connects via an M28x1.5 thread and uses an integrated surface-mounted sensing element to detect radiator or nearby surface temperature, allowing automated modulation of valve position to maintain the chosen setpoint. The device is intended for residential and light commercial heating systems where local temperature regulation at the radiator is required.
Advantages
This thermostatic head provides direct, local temperature feedback through its surface sensor, enabling responsive control of radiator output without the need for remote room sensors. The M28x1.5 threaded connection ensures compatibility with a wide range of valve bodies that accept this standard. Its compact design makes installation straightforward in confined spaces and allows for a discreet appearance on radiators. The product supports fine adjustment of room comfort by modulating flow based on measured surface temperature.
Suitable for
 Domestic radiators with valves that accept M28x1.5 threaded heads
 Apartments and houses requiring individual radiator temperature control
 Light commercial or office spaces where per-radiator regulation is desired
 Retrofit projects replacing manual or incompatible thermostat heads
When it may not be suitable
The surface sensor measures temperature at the valve head or nearby surface rather than an exact ambient room point; for highly precise ambient-room temperature control a dedicated room thermostat or remote sensor may be preferable. It is not suitable for valve bodies that use a different thread standard or proprietary connection, and it cannot be used where electronic or networked central heating control is required unless integrated with compatible components.
Key specifications
 Connection thread: M28x1.5
 Sensing type: surface-mounted temperature sensor
 Application: thermostatic control for radiators
 Installation: direct mount on compatible valve bodies
 Typical use: residential and light commercial heating systems
How to use
Mount the thermostatic head on a compatible radiator valve with an M28x1.5 connection, following the valve manufacturer's installation instructions. Ensure the sensing element has good thermal contact with the valve or radiator surface and that airflow around the sensor is not obstructed. Set the desired temperature via the head's adjustment mechanism; the surface sensor will detect temperature changes and actuate the valve to maintain the setpoint. Periodically check for secure mounting and correct operation, and consult the system documentation if integrating with other control devices.
What to consider before purchase
 Verify that the radiator valve body accepts an M28x1.5 threaded head.
 Decide whether a surface-mounted sensor meets your accuracy needs versus a remote room sensor or central thermostat.
 Confirm compatibility with the building's heating control strategy and any existing thermostatic valves.
 Consider space and clearance around the valve for installation and manual adjustment.
Usage recommendations
For stable temperature control, avoid mounting the valve head near heat sources (e.g., direct sunlight, lamps) or drafts. If room temperature regulation is critical, combine the valve head with a central room thermostat or remote sensor and follow routine checks to ensure the sensing element remains in good contact with the radiator surface.
