The recirculating air damper is used for room heating with warm extract air. On a controller, any
temperature from 10 to 35 °C can be set. Subject to room temperature, the damper servomotor constantly
opens or closes the louvre damper to regulate the set temperature.
Please note: In Germany, in accordance with the occupational safety directive, extract air must not be
routed into workrooms or other rooms people have access to!
Please note: If installed upstream of the optional extract air damper, machine/fan noise in the installation
room will be without attenuation!
