4 Installation of CCM Module and Air Dial
4.1 Electrical connections
1. Connect power cable m to Air unit l.
2. Plug in communication cable k between CCM module j and Air unit.
3. Check the signal. If it is too weak, the CCM module should be placed elsewhere, e.g. on the same
floor as as the Air Dial (see Air Dial Link Test).
4. If possible, place the CCM module close to an ethernet connection for future connection to PC.
5. If accessories (electrical preheating, electrical afterheating, water heating surface or geothermal
surface) are present, the pin on terminals.
Communication cable connections:
1. White/Orange, 2. Orange, 3. Black, 4. White/Blue, 5. Blue, 6. Black
Note! The communication cable can be extended up to 200 m. Use shielded cable , 22 or 24 AWG with 2 x twisted
pair.
4.2 Wireless connection
When powering up the CCM module a green LED will flash slowly, indicating the CCM module has yet to be connected to the Air Dial.
To connect the Air Dial, insert the batteries. The Air Dial starts in installation mode and automatically guides
through the set-up.
1. Set language.
2. Create network (press button on CCM module and then press Air Dial).
3. Set basic step (setting up the main air volume).

4.3 Air Dial
The Air Dial has an integrated temperature sensor. To ensure best possible performance,
place the Air Dial according to following guidelines:
• Place the Air Dial 80-150 cm above floor level.
• Place the Air Dial free of curtains etc.
• Place the Air Dial where the temperature is representative.
• Do not place the Air Dial in bathrooms.
• Do not place the Air Dial in direct sunlight.
• Do not place the Air Dial onto outer wall.
• Do not place the Air Dial directly above heat source.
Air Dial Link Test
Before mounting the Air Dial permanently, perform a link test to ensure that transmission conditions are sufficient for the required location:
1. Press the Air Dial button for 5 seconds to access the Service Menu (The Service Menu remains visible for one hour).
2. Select the Link Test function.
3. The function shows if the transmission conditions are sufficient or not.
4. If the link test fails, see Troubleshooting.

At the end of the network test the Danfoss Link™ CC awaits for all battery operated devices to wake up and report. Follow the instructions
given on the screen. If the network test is running smoothly, there will be no need for further interaction. If the network test is performing
slow, the Danfoss Link™ CC guides through troubleshooting and gives usefull tips for speeding up the process.
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.

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.
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

7 Service Menu
Press Air Dial for 5 seconds to access the Service Menu to change basic settings like language, filter timer, basic
steps etc.
System Reset
1. If the system has already been balanced, make a note of the basic fan steps for later use. The values are
found in the Service Menu: Service > Info > Basic Steps.
2. Remove and re-insert the Air Dial batteries while pressing the button until a beep is heard. The Air Dial is
now in start-up mode.
3. Remove the supply or communication cable.
4. While re-connecting the cable, press the CCM module button until only the green LED is flashing.
5. The system is now reset to factory settings.

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).

until all sensors indicate below +70 °C.

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).

to Demand mode or Programme mode.

Check that unit is mounted on platform,
