Commissioning your Unity ZCV3si … via the fan
Upon first power up, your Unity ZCV3si will commence a diagnostic check, whereby the capacitive touch

(depending on how the unit has been configured).

‘Kitchen and Bathroom’ buttons will
start to flash. Select required flow
rate, the light adjacent to your
selection will go solid.
Boost Airflow button will flash, press
the speed adjustment buttons ‘+/-‘
to required level, repress button to
confirm.
Trickle Airflow button will flash, press
the speed adjustment buttons ‘+/-‘
to required level, repress button to
confirm.

Default setting: Off
To activate, press required button the light adjacent to
your selection will go solid.
The Smart Humidity sensor automatically registers the speed at which the humidity in the room changes. If there
is a rapid change it reacts to a rise in room humidity caused by the user and switches on the ventilator.
The Smart Timer monitors the length of time that there is an occupancy presence within a wet room (via the
‘switch-live’) and provides a fixed over-run time period to best match the length of time that the ‘switch live’ is
active (as shown below):
Note: the first 5 minutes will not activate an over-run.
