Operation

Operation of the AMX 4 can be done in two ways:

• Via Local Web Tool
• Via Airlinq® Online

Both tools allow you to control, monitor, and manage the unit. The Local Web Tool is part of the standard delivery, while Airlinq® Online is optional.

Local Web Tool with Internet Access

The Local Web Tool has four user profiles: 'viewer', 'basic', 'technical', and 'advanced'. Access the unit by entering its IP address in a browser. Log in with your user profile and password.

Local Web Tool without Internet Access

If you do not have internet access, the AMX unit can function as a Wi-Fi access point. Turn off the unit, wait 10 seconds, then turn it on. Search for available Wi-Fi networks; the unit will appear as AM-xxxxxxxxx (where x is the serial number). Connect to it using the password 'fresh_air'. The Local Web Tool will open automatically. Log in with one of the four user profiles.

Airlinq® Online

Airlinq® Online is a professional web portal for Airmaster systems connected via Ethernet. It is designed to control, monitor, and manage ventilation solutions. Access Airlinq® Online via a smartphone, tablet, or PC without installing any software. You need internet access via your web browser. After activating your access via the invitation email, go to https://online.airling.eu/ and log in.

LED Signals

The AMX 4 is equipped with an LED indicating the system's operating status. The LED is located on the back, right side of the unit.

Control Functions

The AMX 4 system combines ventilation and recirculation with heating or cooling.

• Ventilation + Cooling
• Ventilation + Heating
• Recirculation + Cooling
• Recirculation + Heating

Boost Function

The Boost function temporarily changes the airflow. When activated, the unit automatically adjusts the supply and exhaust fans according to pre-programmed values. The standard boost period is 30 minutes with 100% airflow, after which the unit returns to normal operation. The boost period length can be adjusted via Local Web Tool or Airlinq® Online.

CO2 Sensor

The built-in CO2 sensor controls the system based on indoor air quality. If the CO2 level exceeds 400 ppm, the unit adjusts the airflow. When the CO2 level drops below 400 ppm, the unit returns to normal operation.

Propane Sensor

The unit is equipped with a propane sensor that monitors for leaks in the heat pump circuit. If propane is detected, the unit initiates a ventilation procedure to expel the propane safely. An alarm is simultaneously sent to the control system. After the ventilation procedure, the unit stops and can only be restarted after inspection/repair. The propane sensor continues to monitor the unit; if propane is still present, the ventilation procedure is repeated.

External Start (Optional)

An external start function is available as an option, allowing connection to an external start contact. This contact should be a 'sealed potential-free contact' with silver/gold contacts for small signals.

Adjustment of Supply Air Louvers

The supply air louvers can be adjusted to control the throw (length) and spread of the supply air. The louvers are located behind the grille.

Adjusting Louver Angles:

• Standard Spread and Throw: Louvers set for a 45° angle.
• Narrow Spread and Long Throw: Outer louvers on both sides are closed to achieve a longer throw.
• Wide Spread and Short Throw: Outer louvers on both sides are set at a lower angle than the middle louvers.
• Asymmetrical Throw: One side has a smaller louver angle than the other to create asymmetry.

Use a long-nosed pliers to adjust the louvers, being careful as they can break if bent too many times.

Maintenance

Maintenance Plan

Filter Replacement

WARNING: Wear safety glasses, disposable gloves, and a face mask when replacing filters.

CAUTION: Used filters must be disposed of immediately after removal from the unit. Store used filters in a dust-proof bag.

NOTE: Used filters must be disposed of according to their contamination (waste code 1502 for particles, 150203 for atmospheric particles, or 150202 for 'hazardous' substances).

NOTE: All filters must be replaced. Do not attempt to wash or vacuum them. The AMX 4 has two filters on the intake side and two on the exhaust side, each with a coarse and a fine filter.

Replacing Exhaust Air Filters

1. Open the bottom plate on the right side of the unit using the provided key.
2. Open the filter cover.
3. Open the hinges holding the coarse filter in place.
4. Remove the filter and replace it with a new one.
5. Close the coarse filter hinges.
6. Open the hinge holding the fine filter in place.
7. Remove the filter and replace it with a new one. Note the arrow marking on the bottom of the fine filter; this arrow should point towards the center of the unit.
8. Close the fine filter hinge.
9. Close the filter cover.
10. Close the bottom plate.

This completes the exhaust filter replacement. Proceed to replace the supply air filters.

Replacing Supply Air Filters

Follow the instructions in section 9.2.1, "Replacing Exhaust Air Filters", but on the left side of the unit. Refer to Figure 20, Figure 21, and Table 7.

After replacing the filters, reset the filter service indicator (see section 9.2.3).

Filter Service Reset

The standard code for resetting the filter service is 9732. Filter reset is performed either in the Local Web Tool or Airlinq® Online.

Cleaning the Unit

Regular cleaning ensures error-free operation. This section provides guidelines for both exterior and interior cleaning.

Exterior Cleaning

CAUTION: The unit must be switched off before cleaning.

Use a soft, damp cloth to remove dust and dirt. Do not use aggressive cleaning agents like turpentine; use clean water or water with a mild detergent. The space between the unit and the wall/ceiling can be dusted with a dust cloth or a vacuum cleaner with a soft brush attachment. The exhaust grille and ventilation openings should be cleaned regularly, preferably by vacuuming with a soft nozzle.

Interior Cleaning

CAUTION: The unit must be switched off and disconnected from the mains before opening the bottom plates. Ensure no one turns on the power.

Use a vacuum cleaner or a soft brush to remove dust and dirt from the unit. Pay special attention to cleaning the heat exchanger and fans.

Condensate System

CAUTION: The unit must be switched off and disconnected from the mains before opening the bottom plates. Ensure no one turns on the power.

You must remove the bottom plates and the lower steel plates to access the condensate system (see section 7 in the installation manual).

Cleaning

The condensate system consists of three parts. The middle part collects liquid from the other two. You must clean and check all three parts.

1. Disconnect the condensate tray at the rear of the unit by unscrewing the bolts. Cut and remove the cable tie holding the condensate hose.
2. Clean the tray, drain, and hoses. Ensure there are no obstructions in the drain or hose. If you remove the hose, secure it again with a suitable hose clamp.
3. Reassemble the tray.
4. Repeat for the tray at the front of the unit.
5. Disconnect the middle tray.
6. Clean the tray, drain, and hoses. Ensure there are no obstructions and secure the hoses if removed.
7. Refer to Figure 23: Clean the condensate pump if necessary with a damp cloth. There are two pumps, one on each side of the middle tray.
8. Reassemble the middle tray.
9. Perform a check (see section 9.3.3.2).
10. Once the check is satisfactory, reassemble the lower steel plates and bottom plates. Remember to insert a new cable tie to secure the condensate hose; it must not hang loosely.
11. Turn on the unit.

Check

Pour approximately 1.5 liters of water into the condensate tray at the rear of the unit. The water drains into the middle tray by gravity. Check that this occurs and check for leaks. Repeat for the tray at the front of the unit, ensuring water drains to the middle tray and checking for leaks. To check the condensate pumps in the middle tray, briefly turn on the power and check that water is pumped out and that there are no leaks.

Service/Repair

For service or repair, contact Airmaster A/S or your local representative. Contact information for Airmaster can be found in section 4.4 on page 10.
