Installation Manual
NOXMASTER
6.2 Speed Selection
When power to the unit is switched on the display will show LED start-
up pattern 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.
6.3 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.
6.4 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).
If an alternative temperature control is needed due to excessive heat in
the property, please contact after sales to discuss your requirements.
6.5 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.
6.6 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.

IMPORTANT
In the event of RF interference between 84MHz to 89MHz
the fan speed may increase to full speed. Operation will return
to normal when the interference stops.
7.0 HEATER CONTROL (Heater Versions Only)
When the orange LED on the diffuser control panel is illuminated, the heater is
active in autoheat mode and is controlled by the temperature setpoint. When
the orange LED is not lit, the heater is off.
In order to enable the heater, press the DOWN button for five seconds and
release. The orange LED will illuminate indicating that the heater is active and in
auto heat mode.
To turn the heater off, press the DOWN button for five seconds and release. The
Orange LED will no longer be illuminated, indicating that the heater is off.
7.1 Setting the Temperature Set Point
A temperature sensor is fitted to the outlet of the heater and will control the
heater output to maintain the set point. The set point ranges between 5˚C (fully
anti-clockwise) and 15˚C (fully clockwise) and can be adjusted via the min/max
commissioning pot located on the ceiling vent diffuser.
8.0 MAINTENANCE
Appropriate PPE (Personal Protective Equipment) should be worn
during maintenance. Precautions may also be needed to protect the
surrounding area from excess carbon residue.
It is important that maintenance checks are recorded and that the
schedule is always adhered to, in all cases, the previous report should
be referred to.
8.1 Routine Maintenance
•
Check filters and change/clean if required, failure to do so may

Check operation of damper actuators and linkages and adjust as
necessary.
8.3 Replacement Filter Codes
To ensure the carbon filter maintains its high reduction of NO2 the
filter must be replaced once the end of its lifespan has been reached.
The lifespan of the carbon filter in normal circumstances is shown in
