Humidity level trigger
The humidity setting defines at what relative humidity the fan will trigger,
adjustable from 50% to 70% rH.
Comfort mode
Comfort mode changes how the fan boosts. Normally the fan will go into boost as soon
as an LS input is detected and over run for the set period when LS is disconnected. In
comfort mode the fan will not boost until the LS has been on for 5 minutes, preventing
nuisance noise. After 5 minutes of LS being on the fan will run in boost as long as LS is
on and for the over run time after LS is switched off. If the LS is switched off before 5
minutes the fan will not boost. This mode does not affect the pullcord operation, pulling
the pullcord will still activate boost.
Lock feature
The lock feature will prevent the unit from being adjusted after commissioning as a pass
code is required to access the menu. This can be set in the menu to any 3 digit
hexadecimal combination.
If the lock feature is enabled; when a button is pressed the display will show, – – –. At
this point enter the three digit code by first pressing + or – until the first digit is correct
then press MODE to move to the next digit. Repeat until the code is entered and press
MODE to enter the commissioning menu. If the code is entered incorrectly, wait until the
screen switches off then press any button to begin again.
