Regulus 211205300 - Combustion controller 3/4" male thread

Automatic air control for optimal combustion

The Regulus 211205300 combustion controller automatically regulates the air supply to solid-fuel and multi-fuel boilers. The built-in thermostat continuously monitors temperature and adjusts the air inlet flap for a steady and efficient burn.

Why use a combustion controller?

Efficient combustion requires the right balance of air and fuel. This controller ensures that the air supply always matches the temperature, reducing incomplete combustion, smoke formation and heat loss.

Improved efficiency and lower fuel usage

With optimised air flow, the boiler consumes less fuel while generating more usable heat. Homeowners benefit from lower running costs and operators enjoy improved system stability.

Simple installation and wide compatibility

Featuring a 3/4" male thread, the controller is easy to install in new or existing systems. Both horizontal and vertical mounting positions are supported, making it suitable for a wide range of boiler types.
