The Caleffi 472000 is a self-powered thermostatic control head with a remote adjusting knob on a 78 in (2 m) capillary, adjustable from 43 to 82°F (6 to 28°C). The dial mounts on a wall or panel away from the valve, so the occupant can change the setting where the valve itself cannot easily be reached.
Best for radiators where the valve is behind a cover, low to the floor or otherwise awkward to reach, but the occupant still needs to adjust the setpoint.
Specifications from Caleffi data sheet NA10474 and datasheet 01034/23 NA. Reviewed August 2026.
Key Features
Self-Powered Operation
A liquid-filled element expands as the sensed temperature rises and throttles the valve closed. No wiring, transformer or controller is required.
Remote Adjusting Knob
The adjustment dial mounts on a supporting surface away from the valve on a 2 m capillary, so the setting can be changed at a convenient height and position.
43 to 82°F Graduated Scale
Dial marked 0 through 5 corresponding to 43, 54, 61, 68, 75 and 82°F, with a * frost position.
±0.7°F Accuracy
Published control accuracy of ±0.7°F (0.4°C) across the setting range.
Frost Protection
The * position holds a 43°F (6°C) cut-in. Caleffi recommends setting the dial to * over long winter absences to keep the space above 40°F (5°C).
Fits Five Caleffi Valve Series
Couples to the Caleffi 220, 221, 338, 339 and 676 series valve bodies.

Frequently Asked Questions
What does the Caleffi 472000 do?
It is a self-powered thermostatic control head with a remote adjusting knob. The head regulates the radiator valve to hold room temperature, and the adjustment dial mounts away from the valve on a capillary so the setting can be changed where the valve is hard to reach.
How is the 472000 different from the 201000?
On the 201000 the sensor is remote and the dial stays at the valve. On the 472000 the adjusting knob is remote. Choose the 201000 when the valve reads the wrong air temperature; choose the 472000 when the valve reads correctly but a person cannot reach the dial.
Which valve bodies does the Caleffi 472000 fit?
The Caleffi 220, 221, 338, 339 and 676 series valve bodies.
What is the setting range and accuracy?
43 to 82°F (6 to 28°C) on a 0 to 5 scale, with published accuracy of ±0.7°F (0.4°C) and a frost protection cut-in at 43°F (6°C).
