7.1 Speed Settings
The unit has 6 air flow rate (speed) settings. Speeds 3 - 6 are
recommended depending on the size of the dwelling.
The following table shows the flow rates and their corresponding speed
settings.
As an example a one bedroom bungalow should be set to speed 3, and
a large 5 bedroom detached property would require speed 6.
Please note: the heater (if fitted) will not work below speed 3.

7.3 Change Carbon Filter Alert
The carbon filters are required to be changed every five years, the
display on the ceiling diffuser will show the letter ‘C’ once this time has
elapsed. New filters can be purchased direct from Nuaire (please refer
to Section 8.0 below for further details).
To reset the change filter message on the display, press and hold both
“up and “down” button until the letter ‘C’ starts to flash then release
and press the “down” button to confirm.
7.4 Setting the Temperature Speed Control Option
The unit has been designed to continuously run 24 hours a day, 365
days a year (provided the unit is ducted to the outside), as such speed 3
is required.
If an alternative temperature control is needed due to excessive heat in
the property, please contact after sales to discuss your requirements.
7.5 Setting the Thermostat
The thermostat controls the front damper which determines where
the air supply is drawn from (either loft space or external). It’s
recommended that the thermostat is set to 24°C. This setting would
enable the unit to automatically switch from the loft intake (warm air)
to external air once the loft space reached 24°C, provided the unit is
ducted to the outside of the property.
7.6 Time Clock
The time clock controlling the carbon filter bypass is pre-programmed
to operate the bypass (controller must be in "run" mode).
Air passes through the Carbon filter between 6.00AM & 8.00PM.
Between 8.00PM and 6.00AM the air flow is directed through the
bypass.
7.2 Speed Selection
When power to the unit is switched on the display will show the
temperature control option for 2 minutes. Once the start-up pattern
has completed you may now press the “up” or “down” switch to choose
the flow rate appropriate to the property you are installing the unit in.
