F6 Electric heater
overheat
1. Supply air flow too low at high heating
demand.
2. Power failure during operation of the
electric heater; the heater could not cool
down.
3. Electric heater malfunctioning.
1. a. Check air filters and air ducts.
1. b. Decrease the desired temperature.
1. c. Increase ventilation intensity.
2. Check whether the unit is connected to the mains.
3. Contact authorised service.
Once the fault is eliminated, reset an overheating protection thermostat
before restarting the unit. Look for a yellow sticker with the word “Reset”
inside the unit that marks an overheating protection fuse. Depending
on the model, the button may have a black round cap or it may be
integrated inside the heater housing and accessible with a long pointed
object (e.g., pencil) through a specially designed opening.
F7 Heat exchanger
failure
1. Rotor heat exchanger not rotating (only
for DOMEKT R devices).
2. Air bypass damper of the counter-flow
heat exchanger malfunctioning (only for
DOMEKT CF units).
1. Check for foreign objects or debris preventing rotation of the rotor
drum. Check if the rotor belt is not torn.
2. Contact authorised service.
F8 Heat exchanger
icing
1. Antifreeze protection of the heat ex-
changer is malfunctioning.
2. Antifreeze protection is switched off and
outside air temperature is below -4 °C.
1. Check the antifreeze protection settings. Check if an external pre-
heater is working, if used.
2. Check antifreeze protection settings. If an integrated or external pre-
heater is not used, you will not be able to use a device with a counter-
flow heat exchanger when the outside temperature drops below -4 °C.
F9 Internal fire alarm 1. Internal air temperature is above 50°C
2. Faulty temperature sensor.
1. Locate the heat source in the ductwork or unit.
2. Contact authorised service.
F10 External fire alarm A fire alarm was received from the building
fire system.
Once fire alarm is removed, the unit must be started using a control
panel, computer or a smartphone.
F11-F22 Temperature
sensor failure
Temperature sensor(s) faulty or not con-
nected.
Contact authorised service.
F23-F27 Controller failure Controller main board malfunction. Contact authorised service.
F28 Temperature
sensor failure
No signal from temperature sensor located
in the control panel.
Check control panel wiring and cables. Replace the control panel, if
necessary.
F29 Humidity sensor
failure
No signal from humidity sensor located in
the control panel.
Check control panel wiring and cables. Replace the control panel, if
necessary.
F30 Humidity sensor
failure
Faulty or disconnected air humidity sensor
by which the unit is operating.
Check the sensor wiring, replace the sensor or indicate that this sensor is
not used in the settings.
F31 Impurity sensor
failure
Faulty or disconnected impurity sensor by
which the unit is operating.
Check the sensor wiring, replace the sensor or indicate that this sensor is
not used in the settings.
F32 Air flow sensor
failure
Disconnected or faulty air flow sensor(s) It is necessary to check the sensor connections or to change the sensor.
W1 Clogged air flters Replacement of air filters is necessary. Switch off the device and replace air filters. Delete the message after
replacement.
W2 Service mode Temporary special operating mode that can
only be activated by a service specialist.
If the unit has been recently repaired, contact the person who repaired
the unit to determine if service mode can be disabled. Service mode is
turned off by deleting the message.
W3 Return water
temperature low
Warning that the water temperature is lower
than that required to heat the supply air.
Check the condition of a circulation pump and the heating system as well
as operation of a heating damper actuator.
W4 Humidity sensor
failure
One of the two humidity sensors is faulty
or not connected. Device is operating by
another connected sensor.
Check the control panel wiring, replace the sensor or select that this
sensor is not used in the settings.
W5 Impurity sensor
failure
One of the two air quality sensors is faulty
or not connected. Device is operating by
another connected sensor.
Check the control panel wiring, replace the sensor or select that this
sensor is not used in the settings.
W6 Low heat
exchanger
efficiency
1. Message may appear when air is extract-
ed through an additional branch, and, as
a result, the heat exchanger efficiency has
decreased (only for DOMEKT R devices).
2. Supply air volume significantly exceeds
the extract air volume.
3. The unit door is not fully closed and
different air flows are mixed.
1. If additional extraction is not used, the fifth branch must be closed.
Check if an air closing damper installed in the auxiliary extraction duct
is completely closed.
2. If such air flow difference is not required, unify air flow settings.
3. Check that the unit door is pressed firmly and that gaskets are not
worn.
