4.3 Anti-frost protection
The frost protection system ensures that the
secondary side of the heat exchanger
(exhaust air side) does not freeze up as a
result of an imbalance between supply and
exhaust flow. An optimal control of the
volumetric flows is carried out, dependent on
temperature and pressure loss at the heat
exchanger.
4.4 Filter status display
The unit is equipped with a filter status
display that indicates when a filter change is
necessary. You will find more information in
sections 7.2 and 8.1.
