Fan system for energy-saving room heating with conventional heating units switches fan on above defined heating body temperature, off below this or another defined temperature and/or varies fan speed

摘要

The arrangement has at least one fan, a temperature sensor for a characteristic heating body temp. and a circuit for influencing the fan speed. The sensor can be mounted on points on the heating body or return line to detect the characteristic heating body temp. determined mainly by the temp. at the attachment point. The circuit switches the fan on above a defined heating body temp. and off below this or another defined temp. and/or increases/decreases the fan speed with increasing/falling heating body temp.
