What to do if the Danfoss Air a3 shows a fire alarm?
If the Danfoss Fan system's temperature sensor detects a temperature higher than +70°C, examine all rooms and leave the premises.

Why does my Danfoss Air a3 show 'No connection to CCM' alarm?
A 'No connection to CCM' alarm on your Danfoss Fan typically means that communication between the Air Dial remote control and the CCM module has failed. This is often due to an obstacle near the CCM module, such as steel piping, steel objects, or insulation material clad with aluminum foil, or due to radio noise from other wireless appliances. If there is an obstacle, try to move it. If that's not possible, relocate the CCM module to a location with a clear line of sight. If other wireless appliances are causing the issue, try switching them off one by one to identify the faulty device. If these steps don't resolve the issue, contact your installer.
How to stop condensation on window frames with a Danfoss Air a3 Fan?
Condensation on window frames when using a Danfoss Fan indicates that the air exchange is too low to remove humidity, likely due to low surface temperatures on the window frame or glass and humid air. To resolve this, increase the fan step if in manual mode, or switch to demand mode or program mode. Alternatively, enable the Autoboost feature by navigating to Main menu > Settings > Boost > Autoboost on/off.
How to fix a 'Battery low' alarm on my Danfoss Fan?
The alarm indicates that the battery voltage in the Air Dial remote control is too low. Replace the batteries (4 x AAA) in the Air Dial, following the instructions in chapter 3.2.
What to do if the Danfoss Fan shows 'Room air too cold' alarm?
The alarm indicates that the central heating system in the building is not providing heat. Check if the heating system is working correctly. If you cannot resolve the issue, contact the plumber or installer responsible for your heating system.
Why is there noise coming from the air valves of my Danfoss Fan?
Noise from air valves is usually caused by airflow that is too high, excessive pressure over the valve, or a missing silencer on the main duct. Ensure the system is correctly sized to minimize noise issues. Be careful not to accidentally close the air valves during cleaning, as this can create a hissing sound; avoid turning the valves when cleaning.
Why does the Danfoss Air a3 display show a frost icon?
