tings.
6. Switch the ComfoAir to high speed.
7. Install all valves and set the valves according to
the settings given or as set in the reference house.
If no data is known:
– Install the valves and open them as far as
possible.
– Measure the air volumes; starting with the
intake air and then the exhaust air.
– If the measured air volumes deviate from the
nominal air volumes by more than +/-10%,
and the majority of the deviations are posi-
tive,
ensure that all deviations are positive.
If the majority of all deviations are negative,
ensure that all deviations are negative. En-
sure that one supply valve and one exhaust
continue to be fully open.
