Go to ‘App Store’ or ‘Google Play’ and download the ‘Airlinq’ app from Airmaster, see Figure 2 below. Figure 2: Airlinq app Once you have downloaded the app you need to connect to your AMX 4 unit. To do so, you need the 4-digit code connected to your unit.
Enable Bluetooth on your device. Open the app. It quickly displays the Airmaster logo and then displays the screen where you can enter the code, see Figure 4. Figure 4: Enter the unit code Enter the 4-digit code from your unit.
If you wish to turn the unit off or put it in standby mode, you can do so by pressing the ‘power’ icon in the upper right corner of the screen. Each of the options will be described further in the following sections. 5.1.1 ‘Home’...
Until the new room temperature is reached, the display in the middle will show the current room temperature, this way you can keep track of the temperature. 5.1.1.2 Ventilation If you wish to alter the ventilation flow, press the ‘fan’ icon in the middle, this will display the current airflow, see Figure 8 below.
Please note, that the AMX 4 unit prevents situations where conflicting interests occur, e.g. setting the room temperature very low and at the same time setting the airflow to a minimum – it is impossible to lower the room temperature by many degrees if the flow of air is at a minimum.
TVOC are defined during unit setup. If you wish to change the limits for CO and TVOC please use Airlinq ® Online, not the app. 5.1.2 ‘Business card’ icon The ‘Business card’ icon provides contact details for Airmaster support as well as terms and conditions. Figure 13: Contact details 17/40...

8 Adjusting the inlet air slats You can adjust the inlet air throw (length) and dispersion by adjusting the slats. The slats are located behind the louvers, see Figure 17 below. Figure 17: Inlet air slats (front side of the unit) By changing the slat angles you can change the throw and dispersion of the air, see general examples below: Standard dispersion and throw Reduced dispersion resulting in a longer throw...
Use long-nosed pliers to adjust the slats, however, be careful, it is only possible to bend the slats a few times, otherwise, they can break off. Please follow the guidelines below for adjusting the slats. • Standard factory setting at 45 angle dispersion looks like this: Figure 19: Slats 45 degrees angle reduced dispersion and long throw.
• Wide angle dispersion and shorter throw. The outer slats on both sides are at a lower angle than the ones in the middle: Figure 21: Wide-angle slats Asymmetrical throw. One of the sides has a lower slat angle than the other to create asymmetry: •...
