Operating principles

components, including a ComfoAir Luxe heat
recovery unit, a ComfoFond-L and ducting.
These devices are controlled using the
ComfoAir Luxe operating panel.
1. Brine loop pipework.
2. ComfoFond-L.
3. ComfoAir Luxe.
Brine loop pipes are laid in the ground and
connected to the dwelling. In the winter the cold
outdoor air is preheated, ensuring the ventilation
system continues to operate effectively even at
low temperatures. In the summer the warm
outdoor air is precooled.
The ComfoFond-L is specially developed to
operate in combination with a Zehnder
ventilation system of type ComfoAir 350 Luxe
or ComfoAir 550 Luxe.
