Even if the required maintenance is carried out, dust will
build up in the exchanger block. It is therefore of vital im-
portance for the upkeep of a high efficiency that the ex-
changer block is removed from the unit and cleaned
periodically as described below. Clean the heat exchanger
at least every 3 years or when required.
1. Stop the unit by disconnecting the mains.

3.6 Duct System Maintenance
3.6.1 Cleaning extract louvres and supply air diffusers
The system supplies fresh air to your home and extracts the used indoor air via the duct system and diffusers/louvres.
Diffusers and louvres are mounted in ceilings/walls in bedrooms, living room, wet rooms, WC etc. Remove diffusers
and louvres and wash in hot soapy water as required (diffusers/louvres must not be exchanged). Cleaning of diffusers/
louvres can be done as necessary.
3.6.2 Checking the outdoor air intake
Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille, and clean as
necessary. It is recommended to do this at least twice a year.
3.6.3 Checking the roof cowl (if fitted)
The roof cowl (if fitted) connected to the exhaust air duct needs to be checked at least twice a year and cleaned if
necessary.
3.6.4 Checking and cleaning the duct system
Dust and grease deposits may build up in the duct system, even if required maintenance such as changing of filters is
being carried out. This will reduce the efficiency of the installation.
The duct runs should therefore be cleaned/changed when necessary. Steel ducts can be cleaned by pulling a brush
soaked in hot soapy water through the duct via diffuser/louvre openings or special inspection hatches in the duct sys-
tem (if fitted).
It is recommended to do this every 5 years and is normally carried out by authorized companies specialized in this area.
4 Troubleshooting
If problems should occur, please check the items below before calling your service representative.
Fans do not start
1. Check the control panel for alarms.
2. Check that all fuses and fast couplings are connected (main power supply and fast couplings for supply and extract
air fans).
3. Check the week schedule. Fans may be set to OFF in the Schedule airflow settings menu.
Reduced airflow
1. Check the control panel for alarms. Some alarms can reduce the airflow to LOW if active.
2. The unit could be in defrost mode. This reduces the fan speed and in some cases shuts down the supply air fan com-
pletely during the defrosting cycle. The fans go back to normal after defrosting. There should be a defrosting function
icon visible on the home screen if defrosting is active.
3. Speed of fans is linearly reduced when the outdoor air temperature is below 0°C and an outdoor airflow compensa-
tion function is enabled.
4. Check if temporary user mode that reduces airflow is not activated, for example Away,Holiday, etc. Also check dig-
ital inputs Central Vacuum Cleaner and Cooker Hood.
5. Check the airflow settings in the control panel.
6. Check week schedule settings (chapter 2.5).
7. Check filters. Is change of filters required?
8. Check diffusers/louvres. Is cleaning of diffusers/louvres required?
9. Check fans and heat exchange block. Is cleaning required?
10.Check if the buildings air intake and roof unit (exhaust) have been clogged.
11.Check visible duct runs for damage and/or build up of dust/pollution.
212913 | 01_1.8.0

14 | Electrical data GB
12.Check diffuser/louvre openings.
The unit cannot be controlled (control functions are stuck
1. Reset control functions by disconnecting mains power for at least 10 seconds.
2. Check the modular contact connection between the control panel and the main printed circuit board.
Low supply air temperature
1. Check the control panel for alarms.
2. Check the active user functions on the control panel if defrosting function is running.
3. Check set supply air temperature on the control panel.
4. Check if ECO mode is activated on the control panel (it is a power saving function and prevents the heater from
activating).
5. Check if user modes Holiday,Away or Crowded are activated on the control panel or via a hardwired switch.
6. Check the analogue inputs in the service menu to verify that the temperature sensors are functioning correctly.
7. In case of installed electrical/other re-heater battery: Check if the overheat protection thermostat is still active. If
necessary, reset by pressing the red button on the front plate of the electrical re-heater.
8. Check if the extract filter must be changed.
9. Check if the unit has a re-heater battery connected. At very cold outdoor conditions an electrical or water heating
battery might be necessary. A re-heater battery can be acquired as an accessory.
Noise/vibrations
1. Clean fan impellers.
2. Check that the screws holding the fans are tightened.
3. Check that the anti vibration lists are fitted to the mounting bracket and to the back of the unit.
4. Check that the rotor belt is not slipping if the unit has rotating heat exchanger.
