Position and description of visual
filter warning for RVUs
The LED on the included RF switch that lights up orange twice
(after operation) when the filters should be replaced. Periodically replacing
the air filters is important for the optimal funtioning of the ventilation
unit. Not replacing the air filter has an impact on the yield and the energy
effeciency of the device.
