Applications
This thermostat is an automatic control of wood, pellets, coal or anthracite fired solid fuel appliances like roomheaters, boilers, stoves, central heating units.
Its modulating action provides economy in fuel consumption.

Main features
Operation principle: Operation principle: It controls the combustion by throttling the primary air intake to the fire. A flat damper plate at the end of the control arm is moved relative to the air intake port of the appliance in response to variations of temperature at the bulb.
It is actuated by the expansion of liquid in the bulb, through capillary tubing to a diaphragm located in the body.

Body: Zinc plated steel

Shaft: Dia. 6mm, with 4.8mm flat, with 340° angular rotation, providing a 13mm displacement of the 138mm arm

Temperature ranges upon applications:
- Room Air Control 4/40°C (40/105°F).
- Hot water 30/90°C (85/195°F).
- Flue temperature 50/300°C (120/570°F).
Other temperature ranges and displacement available on request (MOQ apply)

Damper plates.
Damper plates are available in circular form in dia. 80mm and dia. 120mm. (Rectangular forms on request).They are spring mounted to permit self-alignment of the plate in the closed position.
Special arm length and damper plates may be made on request to suit application (MOQ apply).
