5.0 CONTROLS
5.1 Fan Speed Adjustment
The unit has 6 air volume (speed) settings. The setting switch is located
on the rear of the fan case. 6 speed indicator lights on the rear panel
of the fan unit include LED’s that, when illuminated, indicate the
corresponding air volume for the unit.
For example, a one bedroom, one person bungalow recommended
setting would be speed 1. A five bedroom, seven person detached house
recommended setting would be speed 6. The installer would advise
this on install.
On initial set up when power is connected the first 3 LED’s will flash
randomly for approximately 2 minutes and will then set at its default
factory setting (speed 2). To select another speed setting simply press
the reset button until the required setting is selected.
A boost switch (supplied) is to be connected to the circuit board
within the unit with 2 core cable (supplied). This 2 core cable is to pass
through the unit as shown opposite. The switch is to be located within
the home for the householder to be able to boost the unit if required.
The unit air volume can be manually boosted to maximum speed by
operation of the boost switch. This is to obtain maximum ventilation
from the unit should the householder require it.
5.2 Smoke / Carbon Monoxide Alarm Automatic Shut Down
If the unit is required to switch off in the event of smoke/CO detection,
alarms are available with separate relay bases from companies such as:
Kidde – www.kiddesafetyeurope.co.uk
Aico Ltd – www.aico.co.uk
This is a mandatory requirement for all units installed in a 3 Storey
property.
