Troubleshooting
If there is any unexpected malfunction of your Ventoxx RV device, try the following to fix the
simplest problems:
Problem
Possible Solution: Please, check…
Low airflow
You notice that airflow is
too low
the fan speed set, and, if necessary, set a higher fan
speed (see 3.3.5.2)
the inner cover panel - it must be open; if it is not, open it
the dust filter: check it for dirt and clean if necessary (see
4.1.1)
the heat accumulator: it could also be contaminated. If
this is the case, please clean it (see 4.1.3)
Cold airflow
You felt that air flow is too
cold
whether the ventilation units are connected in
accordance with the installation instructions. A red and a
blue fan are always working as a pendulum unit (see
2.5.4)
if the device is working in the "High-Performance
Ventilation", and, therefore, there is no heat recovery.
Please, adjust to “Ventilation with Heat Recovery"
operation mode (see 3.3.5.1)
Strange noise
My fan is making strange
sounds ...?
if the ventilator with heat exchanger installation unit is
installed according to the instructions? Perhaps, it is
mounted into the pipe too close to the inner wall of the
house. Then it should be pushed further into the pipe.
Please, install the unit according to the instructions (see
2.5.12)
if the fan is dirty or an alien object is in the fan? – Please,
clean it and remove any alien objects (see 4.1.2)
the set fan speed; perhaps, it is too high. Reduce the fan
speed (see 3.3.5.2)
Stoppage of the Fans:
My fan stopped working…?
if the fan has been connected properly?
if there is a power supply to the fan?
if the control has been connected properly?
If the control has been connected according to the
instructions?
If your answer to all the above mentioned questions is "yes",
there may be a defective control or a defective fan. In this
case, please, contact one of our dealers.
