Overview
Greenwood’s OF100GIP is an intermittent or continuously running extract fan,
designed to offer a simplistic approach to meet Building Regulations and provide
an energy efficient domestic ventilation solution to improve indoor air quality in
dwellings.
The concept revolves around ‘one product’, which has been designed to be
flexible in application (wall, window and ceiling – 230V / SELV installations) and
to meet the performance requirements of all ‘wet’ rooms within a dwelling.
Please refer to section 4.0 for how the OF100GIP can be installed. The
OF100GIP features new SMART technology (fully automatic integral delay /
over-run timer (or run-on timer via pullcord) and humidity functions) which
monitor the homeowners’ environment.
Greenwood TimerSMART
TM
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 in the table below). This removes nuisance running noise and
unnecessary energy wastage typically associated with traditional timers.
Note:
The first 5 minutes will not activate an over-run.
Note:
When the OF100GIP is operated by the pullcord only and has been
commissioned as a timer, the OF100GIP will operate as follows:
• Continuous mode: Boost for 15 minutes then automatically return to
trickle. Manual override available by re-pulling the pullcord.
• Intermittent mode: Turn on for 15 minutes then automatically turn off.
Manual override available by re-pulling the pullcord.
