5.4 Setting basic steps in the Danfoss Link™ CC
Now the Air Unit has been added to the wireless system, and is ready for balancing of the air flow. If the Air Unit has just been added to
the system, the screen will prompt for setting the basic extract and supply air step.
If the system was started earlier/by others, enter the basic settings through the Service Menu by pressing the Air Dial button for 5 seconds. Go through the following steps.
GB .
6 Balancing of the Main Air Volume
To achieve the best possible performance, it is vital to balance the main air volumes (balancing
will also help protecting the house against fungus and dry rot). The system should not be balanced/commisioned at outdoor temperatures below -3°C, as the system will go into frost protection mode (indicated by a flashing icon on the display. If necessary to perform balancing at
outdoor air temperatures below -3°C, remove power for 20 seconds to de-activate frost protection for 90 minutes.
Note! Close all doors and turn off the cooker hood.
1. Remove the front panel from unit by pulling the handles.
2. See the drawing of the duct system, where suggested pre-setting values for all air valves
are stated. Close the valves completely, and turn them full turns towards open (number of
turns as indicated on the duct system drawing). When setting up the systems for which
Danfoss has not dimensioned the duct system, set the supply and extract valves in accordance with the instructions of the project manager.
3. If dampers are included in the system, open these completely.
4. Mount measuring tubes between the unit’s measuring points on the extract side and differential pressure gauge.
5. Find the required flow on the system diagram (sticker on front cover) with the corresponding differential pressure value. If the pressure is too low, adjust the fan step upwards until
you reach the required pressure.
6. Move the measuring tubes to the measuring points on the supply side and use the same
procedure to set the supply air.
7. After the main air volumes have been adjusted, the set-up of individual valves needs to be
carried out. In most cases, this will entail minor changes to the chosen basic steps, but this
can be done in the room by adjusting the valves, or by using the Air Dial to fine tune basic
steps.
Measuring the extract
Adjusting an operational system
1. Press Air Dial for 5 seconds to get access to the Service menu.
2. Press ”set basic step” to activate the special commissioning mode (where all outside influences are blocked - the installer controls the extract and supply air fans completely with
1-100% fan speed). The Service menu remains visible for one hour and then disappears.

Noise from Air Unit a-type unit: vibration noise may occur if unit is
Communication between Air Dial and CCM
module has failed, typically caused by an obstacle between Air Dial and CCM module, e.g.
steel piping, other steel objects, insulation material clad with aluminum foil, etc. Another
cause can be other wireless appliances that
does not conform to wireless standards (radio
noise).
Cable between CCM module and unit is unplugged or defective.
Room temperature is dropping, so the unit
turn off to reduce involuntary heat loss. Alarm
active if Air Dial measures a room temperature
below +10 °C.
Unit or temperature sensor in Air Dial remote
control has detected a temperature higher
than +70 °C. The Air Unit turns off until all sensors indicate below +70 °C.
Dial is defective.
Discharge air flow is larger than supply air flow.
Either balancing was not carried out correctly
during set-up of the system or the Air Unit is in
extreme defrost conditions (can occur at outdoor temperatures below -12 °C).
when humidity is high and surface temperatures are low, typically in bathrooms or utility
rooms, where clothes are drip drying (some
condensation in bathrooms following a shower
is normal, but should disappear within half an
hour).
mounted directly onto joists. Unit should be
mounted on a suitable platform.
w-type unit: vibration noise may occur if rubber spacers are not fitted between unit and
wall and/or if silicone strip is not fitted onto
wall bracket.
Defective fan bearings will produce a ‘grinding
noise’.
If an obstacle has been identified, move
it. If this is not possible, move CCM
module to a better location with a free
‘line of sight’.
If the error occurs due to other wireless
appliances in the house, try switching
these off one by one, to identify the
faulty device.
If none of the above helps, contact Danfoss.
Check cable and reconnect if necessary.
If cable is connected, but error still occurs - contact Danfoss.
Check if heating system is functional. If
the problem can not be solved, contact
plumber/Danfoss.
When error has been remedied, shut
down and restart ventilation system to
resume normal operation. Power can be
disconnected by pulling power cable
from system.
Examine all rooms, leave the house.
When error has been remedied, shut
down and restart ventilation system to
resume normal operation. Power can be
disconnected by pulling power cable
from system.
Contact Danfoss.
System continues to run, but with limited functionality.
Imbalance of flow should be 4-10% in
favour of extract air, but if problems
with doors binding is permanent, contact Danfoss.
If problems only arises during extreme
winter condition, it is due to the integrated defrost function that reduces the
supply air (hence not a defect, but an
expected, and very rare occurrence).
Increase fan step Manual mode or
change to Demand mode or Pro-
gramme mode.
Set Autoboost - on.
Auto bypass.
Check that unit is mounted on platform,
according to installation manual.
Check that rubber spacers and silicone
strip are fitted, according to installation
manual.
If fan ball bearing is suspected to be defective, contact Danfoss.

Error Cause Solution
Noise from Air valves Air flow is too high. Noise is not a problem in a correctly
sized and commissioned system. However, if air valves are closed (e.g. during
cleaning), a hissing noise may occur.
This is not an error, but a standard
mode. The function stops automatically
when the outdoor temperature rises.
Frost icon in display
Pressure is too high over valve.
No silencer is fitted to main duct.
The system is in defrost mode, because low
outdoor temperatures entail a risk of ice forming in the heat exchanger.
