Fan adjustment - Humidity / Timer
Humidity and timer functions are activated when the
voltage is supplied to the Ls terminal via an external
switch or when the humidity level rises above the set %
RH level (adjustable between 60 and 90% RH).
After the voltage to the Ls terminal is disconnected or
the humidity level falls below the set %RH level, the fan
continues to run for the set overrun period between 2
and 30 minutes.
The humidity level is adjusted
by turning the potentiometer
(H) clockwise to increase and
anti-clockwise to decrease. To
set the maximum humidity
level the potentiometer (H)
has to set at the max position
(90%).

Recommended Best Practice
The Building Regulations 2010, Statutory Instrument
Part 9, paragraph 42, imposes a requirement that
testing and reporting of mechanical ventilation
performance is conducted in accordance with an
approved procedure.
Compliance with this requirement by an assessed and
registered 'Competent Person' should follow a 'Best
Practice' process and adopt air flow measurement,
Method A – The Unconditional Method – using a
suitable UKAS certified measuring instrument.
Generically referred to as a 'Zero Pressure Air Flow
Meter' or 'Powered Flow Meter'.
Further information on this method is detailed in NHBC
Building Regulations Guidance Note G272a 10/13 and
BSRIA 'A Guide to Measuring air flow rates' document
BG46/2015

Fan adjustment - Motion sensor / Timer
The fan with motion sensor and timer function switches
on when movement is detected between a distance of
1 and 4 metres from the fan. The sensor has a
detection angle of 100° horizontally.
Once movement ceases, the fan continues to run for
the set overrun period which is adjustable between 2
and 30 minute.

Through the wall installation with flexible
ducting
To maximise airflow rigid ducting should be used.
Where flexible ducting is used the diameter must be
maintained and it is good ventilation practice that the
ducting is extended to 90% of its possible length in
order to maintain the best possible airflow. Ensure
that flexible duct connections are not over tightened to
the fan outlet spigot. The fan and ducting should be
installed in accordance with the requirements of the
Domestic Ventilation Compliance Guide, part of the
Building Regulations.
