5. Connecting the Air Unit to Danfoss Link CC, wireless inclusion Remove the front cover of the Danfoss Link CC by gently pulling it off, pull near the edges of the cover. Press the SETUP pin for seconds to enter the service area. Note! The Air Unit must be added to the network as a service device. For further instructions on the network inclusion, see the installation guide supplied with the Danfoss Link CC. Add any dedicated repeater units (CF-RU) BEFORE adding the Air Unit to the wireless network.

5. 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. Service Options Rooms and Devices Manage Devices Rooms and Deviceses Manage Devices Configure device Select Device 5 Configure Device System settings Air unit System settings Set basic steps 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 - 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 - C, remove power for 0 seconds to de-activate frost protection for 90 minutes. Note! Close all doors and turn off the cooker hood.. Remove the front panel from unit by pulling the handles.. See the drawing of the 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 system drawing). When setting up the systems for which Danfoss has not dimensioned the system, set the supply and extract valves in accordance with the instructions of the project manager.. If dampers are included in the system, open these completely.. 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.. 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. Press Air Dial for 5 seconds to get access to the Service menu.. 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 -00% fan speed). The Service menu remains visible for one hour and then disappears. Measuring the extract Measuring the supply 8 VIEWB0 Danfoss Heating Solutions

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.. 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.. Remove the supply or communication cable.. 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.

Error Cause Solution Alarm: No connection to CCM/link test failed Alarm: No connection via modbus/link test failed Alarm: Room air too cold Alarm: Fire Alarm: Sensor error Abnormally large negative pressure inside the house, doors binding Condensation in window frames 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. Central heating system is not supplying heat. Room temperature is dropping, so the unit turn off to reduce involuntary heat loss. Alarm active if Air Dial measures a room temperature below +0 C. One of four temperature sensors in Danfoss Air 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. Temperature sensor in Danfoss Air unit or Air 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 - C). Air exchange is too low. Condensation occurs 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). 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 -0% 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 Programme mode. Set Autoboost - on. House temperatures are too high House thermostats are set too high. Turn down thermostats. Bypass is disabled on ventilation system. Bypass is disabled on ventilation system. Enable Bypass in Main menu Bypass Auto bypass. Noise from Air Unit a-type unit: vibration noise may occur if unit is 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. 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. 8 VIEWB0 Danfoss Heating Solutions
Error Cause Solution Noise from Air valves Air flow is too high. Noise is not a problem in a correctly Pressure is too high over valve. sized and commissioned system. However, if air valves are closed (e.g. during No silencer is fitted to main. cleaning), a hissing noise may occur. Frost icon in display The system is in defrost mode, because low outdoor temperatures entail a risk of ice forming in the heat exchanger. This is not an error, but a standard mode. The function stops automatically when the outdoor temperature rises. Danfoss Heating Solutions VIEWB0 9
