DRI-ECO-NOX-HEAT
Installation Manual
IMPORTANT
Heater is enabled only when the orange LED is
illuminated.
7.8 Indicator LED's
The sensors and switches include an LED which illuminates when
a button is pressed. A green light shows that communication
between it and the fan unit is taking place. A red light shows that no
communication is taking place and binding may be required.
8.0 HEATER ON (AUTO HEAT) / OFF CONTROL
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.
9.0 MAINTENANCE
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.
9.1 Filter Maintenance
Change carbon filters every 2 years, failure to do so may impair the
performance and efficiency of this unit.
As standard, each unit is supplied with G3 particulate filters which
require replacing every 5 years. If the unit in question has been supplied
with the higher grade ePM10 filters, they should be visually checked
every 2 years and changed every 5 years at minimum. The unit display
will show the letter 'C' once this time has elapsed.
New particulate filters can be purchased direct from Nuaire using the
following part number:
DRIPOS2001-FILTERKIT
(five year filter). To
reset the change filter message, press and hold BOTH “up and “down”
button until the letter ‘C’ starts to flash then release and press the
“down” button.
If the units’ performance has been reduced dramatically or black dust
becomes visible around the outlet diffuser, check that the filter has not
become dislodged in any way.
7.4 Unit Binding Mode
Where wireless sensors/switches are present, they must first be bound
to the fan unit before it can work. In order to bind to the switches/
sensors the fan must be in binding mode. The steps required to enter
binding mode are shown below.
1.
Ensure the fan unit is powered on.
2.
Unit will enter the start-up sequence for 2 minutes when first
powered on. Press the down button on the ceiling diffuser control
panel once, to exit the start-up sequence.
3.
Press and hold both the UP and DOWN buttons for between 20-
30 seconds then release (optimum time is 25 seconds), a single
horizontal bar on the display flashes.
4.
Press "down" to enter binding mode (binding mode last for 5
minutes). The unit will now display a flashing ‘b’ to indicate it has
entered binding mode.
Note: Solid “P” indicates boost, flashing “b” indicates binding
mode.
7.5 Binding 4 Way Switch
Once the fan unit is in binding mode a switch may now be bound.
1.
Press and hold the ‘Boost’ & 'Heater off' button for 2-5 seconds.
2.
The LED will flash GREEN twice when bound.
To check the binding of a switch, press “boost”. A green LED denotes
that the switch is bound and the fan should run at full speed. A red LED
denotes that the switch is not bound.
Note: if “b” and “P” are flashing on the display, the unit is in binding
mode and purge (full speed).
7.6 Binding Sensor
Putting the unit into binding mode (Section 7.4) before powering the
sensors will automatically bind the sensors to the unit. However if they
do not bind follow the below steps.
1.
Put the unit into binding mode (Section 7.4).
2.
Power up sensors (insert batteries for humidity, mains for CO2).
3.
Tap indented button then hold until left hand LED flashes red/
green (ignore red/blue and continue to hold). Release button whilst
flashing.
4.
Tap indented button again, whilst red/green LED is still flashing.
5.
Close binding window on fan control panel by holding both “up” and
“down” for 5 seconds and release.
6.
Check sensor has bound by tapping indented button and look for
the left hand LED to go green. If it displays red, repeat from step 1.
7.7 Setting Sensor Set Point
The sensors will automatically trigger the fan to increase speed once
the sensor set point has been exceeded. To change the sensor set
point, press and hold the indent button for 5 seconds until the status
indication LED flashes BLUE/RED release, the green LED’s illuminate to
show the current sensor set point. Press the button to cycle through
all allowed values, and press and hold for 3 seconds to confirm choice.
If the button is not operated for 10 seconds the set point currently
selected is stored.
Once the selected sensor set point has been exceeded for longer than
the set point delay (10-30 seconds), the fan unit will increase in speed
by 1 and a solid 'b' will be shown on the diffuser display.
