The ventilation unit is not responding to the RF sensors (PIR sensor, 230 V CO
Cause
a) The system is not in Auto mode.
b) The frost protection system is active.
c) With a 230 V RF-CO sensor: no power to the
2
sensor.
d) If using an RF-RH or RF-PIR sensor: the RF
sensor battery is empty.
e) The RF sensor is not paired with the ventilation
unit.
f) The distance between the ventilation unit and
the RF sensor is too large, or there are too
many obstacles interfering with the signal.
g) The OEM codes of the RF sensor and the
ventilation unit are different.
h) The RF sensor is faulty.
i) The ventilation unit PCB is faulty.
The ventilation unit is not responding to the RF remote controls
Cause
a) The frost protection system is active.
b) The battery of the RF remote control is empty.
c) The RF remote control is not paired with the
ventilation unit.
d) The distance between the ventilation unit and
the RF remote control is too large or there are
too many obstacles interfering with the signal.
e) The OEM codes of the RF remote control and
the ventilation unit are different.
f) The ventilation unit PCB is faulty.

Solution
If desired, place the system in Auto
●
mode.
When the outside temperature rises
●
above -1°C, the fan will start running
again.
Install a pre-heater in the supply duct for
●
outside air.
Check whether power has been switched
●
off or interrupted. Restore power.
Replace the battery.
●
Restart the commissioning procedure
●
and pair the RF sensor.
Try pairing the devices again. If this does
●
not work, move the RF sensor to a
location where there are fewer obstacles.
Replace the RF sensor with one that has
●
the correct OEM code.
Replace the motor module PCB with a
●
PCB that has the correct OEM code.
Replace the RF sensor and re-pair it with
●
the unit.
Replace the PCB and carry out the
●
commissioning procedure again.
