Description Behavior Likely problem Solution
26 - Failure in the
pressure sensor of the
exhaust filter.
Unit is
ventilating
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
27 - Failure in the pres-
sure sensor of the inlet
filter
Unit is
ventilating
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
28 - Failure in the pres-
sure sensor of the inlet
fan
Unit is not
working
correctly
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
29 - Failure in the
pressure sensor of the
exhaust fan
Unit is not
working
correctly
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
30 - Failure in the pres-
sure sensor of the VAV
supply channel
Unit is not
working
correctly
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
31 - Failure in the pres-
sure sensor of the VAV
C4 exhaust channel
Unit is not
working
correctly
Pressure sensor
failure
Check the supply point for mechanical damage or
whether it is clogged by dirt, or whether the supply
hoses are free. The pressure sensor will likely need
to be replaced
32 - Air quality sensor
failure
Unit is
ventilating
Defective air quality
sensor
Check that the quality sensor is connected correctly
or check that it is operating correctly (output signal
value)
33 - Failure in the
recirculation relative
humidity sensor
Unit is
ventilating
Defective relative
humidity sensor
Check that the humidity sensor is connected cor-
rectly or check that it is operating correctly (output
signal value)
34 - Failure in the sen-
sor of external tem-
perature from BMS
Unit is
ventilating
Defective sensor in
BMS or incorrectly
received data
Check that the address and values of the sensor in
the BMS system are correct. Check that the sensor
in the BMS system is working.
35 - Failure in the REK
antifreeze protection
relative humidity sen-
sor
The unit is
ventilating th
Defective relative
humidity sensor
The communication cable to the relative humidity
sensor is damaged or disconnected. The humidity
has exceeded the permitted limit and the sensor
may temporarily read incorrect values. Check the
connection of the sensor. Set its address and check
that it is not flooded. Replace if necessary.
36 - Module B error
Unit is not
working
The unit cannot con-
trol the peripherals
connected to Module
B
Unable to communicate with module B. Check
whether the communication cable between control
boards A and B is damaged. If necessary, replace
module B.
37 - Condensate pan
overflow
Unit is not
working
The level sensor has
detected an extreme-
ly high level of water
in the condensate
pan
Check that the level sensor is connected correctly or
check that it is operating correctly, or whether the
condensate drain is clogged, preventing the conden-
sate from draining properly.
50 - Inlet filter
clogged > 80%
Unit is
ventilating
Clogged filter Filter change recommended
51 - Exhaust filter
clogged > 80%
Unit is
ventilating
Clogged filter Filter change recommended
70 - Anti-freeze protec-
tion of the water heat
exchanger
Unit is
ventilating
The anti-freeze pro-
tection of the water
heat exchanger is
active
The automatic protection of the water exchanger
has been activated in order to prevent damages due
to low temperature. This is an autonomous function
and will be terminated once the risk of frost disap-
pears.
