What is weather compensation?

Weather compensation interacts intelligently with the boiler to reduce radiator water temperatures based on outside temperatures, which increases efficiency without compromising user comfort. Many users have reported significantly improved comfort, as the boiler is better able to maintain a steady internal temperature by adjusting boiler output to account for changes in the weather. Weather compensators can be a simple external sensor feeding weather data back to the boiler.

Ideal provide an external weather sensor that can be purchased as an accessory.
