How do I change my fan’s settings

Press button on fan

If the 'trickle or boost' symbols with a flow rate lights up, 
your fan has been commissioned locally. You can change 
the following settings:

Touch Smart Timer button for on or off

Touch Smart Humidity button for on or off

If only the 'trickle or boost' symbols & no airflow speeds light 
up, your fan has been commissioned via our APP.  To review / 
change your settings, download our ‘Unity CV3 APP’ from  
Google Play. You can view your settings by removing the front 
cover and placing your android device over the NFC symbol. 
Follow APP to read settings on your device for:

If fan setup has been locked you cannot change anything

If unlocked you will be able to adjust:

Smart Humidity on / off

Selected timer mode:
o Smart Timer on / off
o Silent mode delay-on-timer, 1-60 minute range

Night mode setting to deactivate the boost mode during 
your selected time period

Troubleshooting

I don’t think that my fan is working

My fan is running all the time

My fan is running faster and noisier

My fan still runs faster and noisier

when I turn the light off

Why can’t I turn the fan off

Answer

The fan is very quiet when the room’s light is off, but it is still 
extracting and working to provide you with enhanced comfort

If in doubt, remove the front cover to expose the fan. If 
the fan impellor is not rotating then contact your local 
installer.

This is correct; it will run at a low speed whilst your room is 
unoccupied to provide continuous ventilation

Your fan will automatically go into “boost” mode when you turn
the light on or if the Smart Humidity is activated, when you have
a bath / shower / generate steam via cooking  

The fan will run at a faster speed which generates more noise as
more air is being extracted

Has the bathroom light been left on for more than 5 minutes?

If yes, your fan has the Smart Timer activated and the fan will run
at the higher noisier “boost” rate between 5 - 15 minutes and it
will then return to the lower quieter continuous speed setting

Your fan has been designed to ventilate the room continuously (i.e.
24/7) to improve the indoor air quality and enhance your comfort
