Follow this procedure to programme the ComfoAir (after
installation):
1. Set the ComfoAir in programming mode.
a. Press OK. The display shows SHIFT for 8 sec-
onds.
b. Press MENU before the SHIFT text disappears.
The display now shows COMF.
c. Press

In programming mode, the bypass valve is al-
ways closed. After 30 minutes, the ComfoAir au-
tomatically terminates the programming mode.
2. Close all windows and outside doors.
3. Close all inside doors.
4. Check the presence of structural overflow provisions.
The structural overflow provisions must be at
least 0,41 inch per gallon/second (12cm
2
per l/s).
5. Check if both fans function in the three speed set-
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 are known:
– Install the valves and
open
them as far as pos-
sible.
– 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 is positive,
ensure
that all deviations are positive. If the majority of
all deviations is negative,
ensure
that all devia-
tions are negative.
Ensure
that one supply valve
and one exhaust continue to be fully open.
