The Brahma TGRD91 18047158 control boxes can operate with non-volatile or volatile blocking. In case of non-volatile blocking, the controller can be restarted only after a manual reset of the system. In case of volatile blocking, an interruption of the power supply and subsequent recovery is required to restart the controller, excluding switching of the heating device.

The application of the units includes combined heating and steam boilers, hot air generators, radiation tube heaters, convector heaters with a fan, water heaters, washing machines, stoves and monoblock burners.

The Brahma TGRD91 18047158 gas control units comply with EN 525, EN 1020 and EN 1319 standards for gas hot air generators, and for oil hot air generators they comply with DIN 4794 standard.

The design of the blocks includes an innovative circuit and surface mounting of components, which significantly reduces the size of the printed circuit board. Additional protection elements include a varistor, an internal available fuse, a built-in electromagnetic interference filter and the installation of a resistor.

The functions of the Brahma TGRD91 18047158 burner control units include flame detection based on the properties of rectification or light radiation, the use of microcontroller technology to accurately set the ignition time, an integrated electronic ignition transformer and support for connecting remote lock and reset signals.

The units provide high electrical reliability, are protected from damage, provide a long service life and support various modes of operation and types of fuel.
