AVT2990 B

In many houses traditional coal-fired central heating boilers are used. Their disadvantage is the lack of automation, which means manual control of the chimney draft, i.e. proper closing down of the ash pan and door. The most critical moment is firing up, when to obtain the right temperature of the boiler, the chimney draft must be large. At the right moment, the oven must be closed down - further heating may cause water boiling in the central heating system.
The system is a simple controller that signals too high water temperature in the boiler. After reaching the programmed value, an audible warning sounds.

The device is especially recommended for users of traditional coal boilers
