The video discusses the problems that had to be faced during the commissioning of a 10.4 MW boiler:
an inverted three-way valve (again);
incorrect burner connection;
Logamatic at an industrial boiler;
imitation of sensor connection;
two serial frequency converters (for the first time in my practice);
a disconnectable safety circuit on the gas valve;
and much more :))).
Enjoy watching.
