5.6 Testing of the bypass and other
functions
Go to the service/diagnostics level as described in
section 5.5. Now test successively all functions in accordance
with the above table. If the bypass is not connected or if a
sensor is defective, the display will show the “-” symbol.
5.7 Reset to the Factory Setting
• Press the “prog” button for 15 seconds to reset the controller
to the default setting.
As soon as the display lights up twice, the controller is
completely re-set to its default settings. This means that you
will have to perform all individual settings again.
5.8 Domestic Ventilation Unit Adjustment
Adjustment procedure
First of all ensure that the overall air flow calculated for the
installation is reached by the system. Then adjust the air
flow rates for the individual living spaces. Finally adjust the
individual air flow distribution within each living space.
Total Air Flow Adjustment
First adjust the desired air quantity calculated when the
system was designed with the remote control for all operating
modes (installer level). Proceed step by step as described in
table 5.1, page 19. In the table you will find the information for
the desired values.
NOTE: The planned air flow must be in the in the day mode
(2nd stage) because this is the standard operation mode.
Adjusting the air quantities at the system
1. Adjust all the exhaust and fresh air valves in the living
rooms to the middle opening of about 50 %. Then proceed in
accordance with the instructions given in the manufacturer
operating manual.
The air speed must not exceed 1.5 m/s at a distance of 50 cm
from the valve.
2. Make sure that all valves in the existing air duct manifolds
are completely opened.
3. Switch the domestic ventilation device into the operation
mode “day mode” using the remote control.
4. Measure the partial air flow at the strings with control
dampers if there are some available. Correct these settings if
required by adjusting the control dampers.
5. Open, if necessary, air inlet and air outlet valves if the
desired total air flow has not been reached.
6. Raise the ventilator revolution speed using the values in
table 5.1 if the total air flow is too low.
7. Go to the installer level in the remote control by pressing
the “mode” button for 10 seconds.
8. Press the
“prog” buttons until “C-AIR” appears on the
display.
9. Correct the inlet air flow by pressing the
- or + buttons until
the inlet and the outlet air volume are equal (see table 5.1).
