2.0 Overview
2.1.0 Greenwood’s Samika fan range has been designed to offer a simplistic approach to meet
Building Regulations and provide an energy efcient domestic ventilation solution to improve
indoor air quality in dwellings. The fan may incorporate fully automated integral controls which
monitors the homeowners’ environment.
2.1.1 Greenwood TimerSMARTTM monitors the length of time that there is an occupant present
within a wet room (via the ‘switch-live’) and provides a xed over-run time period to
best match the length of time 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.
Note: The rst 5 minutes will not activate an over-run.
Time ‘Switch Live’
or Pullcord is Active
‘Switch Live’
Over-run Period
0 – 5 minutes No over-run
5 – 10 minutes 5 minutes
10 – 15 minutes 10 minutes
15 – 20 minutes 15 minutes
To comply with Building Regulation requirements for intermittent ventilation within
windowless rooms, an over-run timer of 15 minutes can be achieved by pulling the pullcord
only.
(Manual override available by re-pulling the pullcord)
2.1.2 Greenwood HumidiSMARTTM 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 occurs with the changing seasons and during the night.
