Bypass
In the summer, or when heat recovery is not desirable, the air is not passed through,
but past the heat exchanger thanks to a bypass module. This makes it possible to
ventilate the home with fresh outside air in the summer situation, during the night,
so that the home is relatively cool again in the morning. The bypass opens when the
inside temperature exceeds the set comfort temperature of 23°C and the outside
temperature exceeds 15°C.
Frost protection
When the outside temperature in winter is around freezing, it is possible for ice to
form in the exchanger. Cold air is blown into your house as a result. To prevent this,
the HRC will heat the exchanger in time using the warm indoor air from your home.
The unit will temporarily create an imbalance to achieve this.
For the MaxComfort models, the built-in preheater switches on and warms up the cold
incoming outside air.
Humidity sensor
Your HRC is equipped with a moisture sensor, which measures the moisture content in
the extracted air from the kitchen, bathroom and toilet. If the built-in humidity sensor
detects that the humidity is rising, for example during cooking or showering, the unit
will automatically switch to a higher setting. The unit will switch back to the lower
position 15 minutes after showering or cooking.
Filters
The HRC has two filters. A filter for filtering the supply air and a filter for filtering the
extracted air. The supply filter ensures that only clean air enters your home and that
dust, soot and insects remain outside. Optionally, you can also use a pollen filter for
the supply filter. The extractor filter also ensures that the air from your home is filtered,
so that the pollution to the exchanger is kept to a minimum.
For an optimal indoor climate, we recommend that you clean your filters every 3 months
and replace them once every 6 months. The HRC is equipped with a filter
indication, which indicates when the filters must be cleaned. For more information
about cleaning your filters, see Chapter 5.
Caution:
Ensure adequate air supply. Never tape or close the valves!
