The Caleffi 200000 is a self-powered thermostatic control head with a built-in sensor, adjustable across 45 to 82 deg F (7 to 28 deg C). It fits a Caleffi thermostatic radiator valve body and holds room temperature at the dial setting without power or controls.
Best for radiators with free air circulation around the valve, where the head can sense room temperature directly.

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.
Built-In Sensor
The sensing element is integral to the head, suited to radiators with free air circulation around the valve.
Setting Range 45 to 82 deg F (7 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.

Frequently Asked Questions
What does Caleffi 200000 do?
It is a self-powered thermostatic control head. A liquid-filled sensor expands as the room warms and throttles the radiator valve, holding the room at the dial setting without wiring, power or a controller.
Does Caleffi 200000 work on its own?
No. The head threads onto a Caleffi thermostatic radiator valve body, which is ordered separately. Heads and bodies are selected independently so the same head suits angled or straight bodies in several sizes.
What is the warranty on Caleffi 200000?
Caleffi covers this product under its standard two-year limited warranty against defects in material and workmanship from the date of shipment. ZOT Supply is an authorized Caleffi distributor.
