HINWEIS
ºº º ºº º
NOTE
Note: Once the fault has been rectified, it is acknowledged
with a power reset (switch off the power supply for 5 s and
switch it on again).
11.1 Internal sensors
The ventilation unit is equipped with internal sensors (in the
outside air and exhaust air) for temperature, humidity and VOC
(air quality) and with two further sensors in the fans for measur-
ing temperature, humidity, speed and volume flow.
The outside air and exhaust air sensors must be completely re-
placed in the event of a malfunction. If the measured values
from the fans fail, the fans should also be completely replaced.
11.2 Replacing fans
Fig. 11.2:Left fan
Fig. 11.3:Right fan
If a fan has to be replaced, it can only be removed once the EPP
condensate plate has been carefully removed to the front and
the cable has been disconnected.
If the incorrect assembly is fitted, the retaining plate (installa-
tion on left or right) can be modified, see Fig. 11.2 and Fig. 11.3.
The assignment for control as an exhaust air of outside air fan is
defined by the colour of the connecting plug in the wiring har-
ness (outside air blue, exhaust air black).
To teach in the new fan, load the factory settings in the service
menu, carry out the fan configuration and re-enter the unit con-
figuration (for U/V see type plate).
11.3 Replacing the bypass
If the bypass has to be replaced, it can be directly disconnected
from the bypass motor and removed.
Insert the new bypass in the correct slot and connect.
It starts functioning and performs a trial run once the power has
been restored.
11.4 Replacing the heating register
For procedure, see chapter 4.3.
It starts functioning once the power has been restored.
