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):
Time 'Switch Live' is Active
