What is the Intelligent Blower Control? Thanks to the control of several parameters, the heating regulation can optimize the heating output and the blower speed, resulting in:  Low electrical consumption and low-noise in regular operation (lower motor speed but same heat output)  High heat-output availability for applications with higher back pressure  Up to 4.0 kW heat output  Very low electrical power consumption thanks to Intelligent Blower Control  Very silent operation thanks to low blower speed and silent fuel pump DP42.4  Automatic altitude adjustment up to 2,200 m as a standard  Additional available automatic high altitude adjustment up to 5,500 m  Automatic cold-start function for quick warm-up
