2.0 Overview
2.1.0 Zehnder’s adaptive fan range has been designed to offer a simplistic approach to meet local

indoor air quality in dwellings. The fan may incorporate fully automated integral controls which
monitors the homeowners’ environment.
2.1.1 Smart Timer monitors the length of time that there is an occupant present within a wet room
(via the ‘switch-live’)DQGSURYLGHVD¿[HGRYHUUXQWLPHSHULRGWREHVWPDWFKWKHOHQJWKRIWLPH
that the ‘switch live’ is active (as shown in the table below). This removes nuisance running
noise and unnecessary energy wastage typically associated with traditional timers.

2.1.2 Smart Humidity monitors the ambient humidity within the wet room environment and looks for
short peaks of humidity made by either cooking, showering or bathing. This smart
technology ensures that your fan is only running when required, removing nuisance running
noise and unnecessary energy wastage typically associated with increases to background
humidity which naturally occur with the changing seasons and during the night.
