## Summary description

Thermostatic radiator head IMI Heimeier DWZ (MPN 7400-00.500) is a temperature control valve head for radiators and convectors. Designed to regulate room temperature by adjusting flow through the radiator valve, it provides precise setpoint control and simple manual operation. Suitable for use in residential and commercial heating systems where a compatible valve body is installed.

## Long description

Thermostatic Radiator Head IMI Heimeier DWZ is a manual temperature control head for radiators and convectors designed to regulate indoor comfort by varying the flow through a compatible radiator valve. The unit provides precise setpoint control with a simple rotating knob and a clear temperature scale, making it suitable for residential and light commercial heating systems where an IMI Heimeier-compatible valve body is installed.
Advantages
The IMI Heimeier DWZ head offers straightforward mechanical operation without the need for external power or wiring, enabling reliable temperature control even during power outages. Its compact form factor and standard mounting interface allow for quick replacement or upgrade of existing radiator valves. The clear marking on the control knob supports repeatable setpoint selection while the internal mechanism provides stable modulation of flow according to the chosen setting.
Suitable for
 Individual room temperature control on domestic radiators
 Retrofit projects to replace older or manual valve heads
 Small commercial spaces with standard radiator valve connections
 Systems where mechanical, battery-free operation is preferred
When it may not be suitable
This thermostatic head is intended to work with compatible valve bodies; it will not function if the radiator valve type or mounting interface is incompatible. It is a manual, mechanical device and does not provide programmable schedules, remote control, or smart-home integration.
Key specifications
 Function: manual thermostatic temperature control for radiators and convectors
 Control type: rotating knob with temperature scale for setpoint selection
 Power: mechanical operation, no external power source required
 Mounting: standard thermostatic valve interface (compatible with IMI Heimeier valve bodies)
 Application: residential and light commercial heating systems
How to use
Mount the thermostatic head onto a compatible valve body according to the valve manufacturer’s instructions and secure it using the head’s locking mechanism. Rotate the control knob to the desired temperature position indicated on the scale; the internal sensor and valve spindle will adjust flow to maintain the selected setpoint. For maintenance, follow standard radiator system procedures: isolate and drain the circuit if valve replacement is required. Regularly check for free movement of the head and ensure the sensor area is not obstructed by curtains or furniture for accurate control.
What to consider before purchase
 Verify compatibility with the radiator valve body and mounting interface in your system
 Decide if mechanical, non-programmable control meets your needs versus programmable or smart thermostats
 Check physical clearance around the valve for knob operation and maintenance access
Usage recommendations
Position furniture and curtains to avoid covering the thermostatic head sensor area, set comfortable mid-range values for everyday use and lower setpoints during unoccupied periods to save energy. For system-wide temperature balance, adjust heads gradually and allow time for the system to stabilise after each change.
