Problem
Heater battery overheated
Frost protection for warm water
heater battery
Overheated fan in the fresh air box
Defective thermal contact in the fan
in the supply air unit
Defective fuse in the electronics of
the main unit
Defective water temperature sensor
in the return
Defective duct sensor or risk of unit
freezing
Defective temperature sensor
TE-4 outside air (black)
Electric heater overheated
Defective electronics protection
for electric heater
Extract air unit fan overheated
Defective thermal contact in the fan
in the extract air unit
Defective temperature sensor in the
extract air unit
Broken data cable
Defective fuse in the electronics of
the extract air unit
Interrupted power supply
Loose connection of power cable
Service switch in position 0
Power failure / voltage does not
reach the required values
The fuse switch is under-dimensi-
oned
There was a short circuit
The fan filters are contaminated
Supply air or extract air ducts are
blocked
The wheel of the fan is loose or
damaged motor bearing
Components overheated
Burnt dust on electric heater
Anti-freeze protection active
Frost protection for warm water

Solution
Check whether the air can circulate freely in the
unit, the heater battery is not sufficiently cooled.
Check whether temp. in duct is not < 8°C with an
outside temp. of < 10°C.
Troubleshooting on motor: faulty bearing, short cir-
cuit, increased power consumption, low load on
the fan (idling). Do not activate fan until the error
has been rectified.
Check whether the cable to the motor's thermal
contact is broken or if fan motor has overheated.
Change the fuse in the electronics of the main unit.
Check whether the sensor is correctly fitted.
Replace sensor if it is defective.
Check whether the sensor is correctly fitted.
Replace sensor if it is damaged. If the unit has a
warm water heater battery and the temperature in
the duct is < 8°C, it concerns the frost protection.
The error message will disappear after another
temperature rise.
Check whether the sensor is correctly fitted.
Replace sensor if it is damaged.
The temp. at the safety sensor of the electric heater
exceeds 60°C. Determine overheating reason (po-
tential contaminated filter).
Check whether the sensor is correctly fitted.
Replace sensor if it is damaged.
Troubleshooting on motor: faulty bearing, short cir-
cuit, increased power consumption, low load on
the fan (idling). Do not activate fan until the error
has been rectified.
Check whether the cable to the motor's thermal
contact is broken or if fan motor has overheated.
Check whether the sensor is correctly connected
to the terminals of the extract air unit controller.
Replace sensor if it is defective. If this sensor is
defective, the supply air unit will control the temp.
according to the sensor in the control unit.
Check the extract air unit.
Change the fuse in the electronics of the extract air
unit.
Check if there is an extract air unit power failure.
Check the power cable
Check if the service switch is in position I.
Check voltage at the connection to the main
connection.
Check that the correct type and correct capacity of
the safety switch have been used.
Check all electrical connections of the unit, motors,
preheaters, supply cables and external components
for short circuits.
Check the air filter. If it is contaminated and this is
not indicated in the display, a new filter unit must
be installed.
Check the duct system (blocked intake distributor
elements, closed dampers...)
Check whether the fan turns freely. Replace dama-
ged fan.
Occurs at the beginning of winter operation. Smell
dissipates with regular filter cleaning. Inadequate
filter maintenance can lead to dust deposits on the
electric heater.
Retry after a few minutes. Otherwise, check for suf-
ficient warm water flow. Check water temperature
in the display menu - Unit will activate at 30°C.
If the error is not rectified automatically: Check the
hot water supply, ventilate the lines, check the cir-
culating pump (potential blockage)
