The new W-FM 25 combustion manager has additional, freely configurable plug-in positions and upgraded bus connections which extend the capabilities for digital control of the combustion process. It has been designed for use in Weishaupt's compact WG10 to WG40 gas burners and WL30 to WL40 oil burners.

The new W-FM 25 replaces the older W-FM 20, 21, and 24 models, with which it is 100 % backwards compatible.
