User Information
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 Technical Services on
+ 44 (0) 1276 408402
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 HumidiSMART 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 TimerSMART 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
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 TimerSMART button for on or off
Touch HumidSMART 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 our
website or via 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:
HumidiSMART on / off
Selected timer mode:
o TimerSMART 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
