The ventilation unit must run continuously and the desired effect is regulated from the
control panel. It is possible to switch off the heat recovery for example during the summer
when the outside and inside temperatures are the same, or when one wants to cool the
indoor air with cool night air. During the summer the house can be kept cool by allowing
the heat exchanger to run and recover the cool inside air.
Regulating the proportion of supply air and exhaust air.
The exhaust air flow should
be 5 - 10 % greater than the supply air flow. This is performed by accurately measuring the
air flow through all of the valves with for example a thermo anemometer and by adjusting
them to the correctly calculated values. A correctly balanced system returns a good heat
recovery rate and keeps a slight negative pressure in the building. The negative pressure
keeps the humidity away from the structures. When an adjustment is made, the filters must
be clean and all the valves and outer grilles must be in place. There must not be an insect
net over the fresh air grille.
