Thermostatic Radiator Valve Head Herz with Remote Sensor, Adjustable 16–28°C, Model 1726040

Thermostatic Radiator Valve Head Herz with Remote Sensor, Adjustable 16–28°C, Model 1726040 is a thermostatic control unit for radiator valves that separates the temperature sensor from the valve actuator. The device allows setting a target room temperature between 16 and 28 °C and adjusts coolant flow through a compatible valve body to maintain the selected setpoint. The remote sensor is intended for placement away from the radiator to avoid local heating effects and to provide accurate ambient temperature control in residential and commercial spaces.

Advantages

The Herz thermostatic head with remote sensor offers precise temperature regulation within the 16–28 °C range and eliminates the influence of direct radiator heat on the sensor by using a detached probe. Its design facilitates individual room temperature management, which supports lower energy consumption when compared with central or manual control. Compatibility with standard valve bodies and a clear adjustable scale make commissioning and adjustment straightforward for installers and users.

Suitable for

• Room-by-room temperature control in apartments and houses
• Office and light commercial radiator installations requiring discreet sensor placement
• Renovation projects where precise setpoint control is needed without relocating radiators
• Applications aiming to reduce heating consumption through localized control

Key specifications

• Adjustment range: 16–28 °C
• Control type: Thermostatic with remote sensor
• Sensing element: Remote temperature sensor (detached probe)
• Compatibility: Designed for manual/thermostatic valve bodies used on radiators (check valve type and connection dimensions before installation)
• Adjustment interface: Mechanical rotary knob or scale for setpoint selection
• Intended use: Indoor heating systems with water radiators

How to use

Install the thermostatic head on a compatible radiator valve body according to the valve manufacturer’s instructions and mount the remote sensor in the room at a representative location away from direct sunlight, drafts, or heat sources. Set the desired temperature by rotating the adjustment control within the 16–28 °C range; the thermostatic head will modulate coolant flow to reach and maintain the selected setpoint. Check for correct mechanical engagement with the valve stem and ensure the sensor cable is routed safely and fixed to avoid strain.

Usage recommendations

Place the remote sensor at approximately 1.0–1.5 m height on an interior wall, away from windows, doors, and radiators, to ensure accurate ambient temperature readings. For balanced system performance, combine room-level thermostatic control with appropriate hydraulic balancing of the radiator circuit and regular system maintenance.
