FAQ

How do I shut the ventilation system down completely?

The system cannot be shut down completely, this is to prevent mould growth in your house, among other things. The system

can, on the other hand, be switched permanently to the low or unoccupied setting for maximum energy saving.

I can't hear the ventilation system, is it actually working?

Duco's ventilation systems are whisper-quiet. You can check whether the system is working by switching the system (tem-

porarily) to the high setting and feeling an exhaust vent.

What happens if there is a power failure?

You don't need to do anything: the system will restart automatically and operate correctly. During this restart the LEDs on

controllers with light-emitting buttons will light up yellow momentarily. This can take a few minutes.

How much energy does my ventilation system consume?

The central extract unit's energy consumption will depend on the number of rooms being ventilated. Energy consumption

will be reduced to a minimum by using pressure-controlled fans.

Do I need to maintain the system?

Yes, please contact your installer for annual maintenance.

A LED is flashing on the controller

There is a network problem, refer to your installer for a remedy.

Can I switch off the LEDs on the controller?

Yes, long-press 'AUTO' to switch the LEDs on and off.

The system is very noisy. What is happening?

If the noise occurs suddenly, then it may be the case that the ventilation system is restarting, after a power cut, for example.

The LEDs on any controllers with light-emitting buttons will light up yellow in that case. After a few minutes, once the LEDs

indicate the normal situation again, the central extract unit will slow down and the system will revert to quieter operation.

If the system starts making more noise gradually, it may be the case that the central extract unit is coming up against

increased resistance, due to clogged exhaust vents for instance. Check the exhaust vents in each room and clean them as

necessary. Please contact your installer if the problem persists.
