The Caleffi 472000 is a self-powered thermostatic control head with a remote adjusting knob, adjustable across 43 to 82 deg F (6 to 28 deg C). The adjustment dial is mounted away from the valve on a capillary, so the setting can be changed where the valve itself is difficult to reach.
Best for radiators where the valve is behind a cover, low to the floor or otherwise awkward to adjust by hand.

Key Features
Self-Powered Room Temperature Control
A liquid-filled sensor expands and contracts with room temperature, closing the valve as the room reaches setpoint. No wiring, power supply or controller is required.
Remote Adjusting Knob
The adjustment dial is mounted away from the valve on a capillary, so the setting can be changed where the valve itself is difficult to reach.
Setting Range 43 to 82 deg F (6 to 28 deg C)
Graduated dial with a repeatable scale, allowing each room to be balanced to its own setpoint.
Fits Caleffi TRV Bodies
Threads onto Caleffi thermostatic radiator valve bodies, so heads and bodies can be selected independently.
Capillary Length
Supplied with a 2 m capillary, setting how far the sensor or adjuster can be mounted from the valve.

When should the remote adjusting knob version be used?
Use it where the valve is behind a cover, low to the floor or otherwise awkward to adjust by hand, so the occupant can still change the setting at a convenient position.
