DRI-ECO-HEAT-HC - Installation and Maintenance
11.0 FILTER MAINTENANCE AND REPLACEMENT
The filters are required to be changed every five years, the display will show the
letter ‘C’ once this time has elapsed. New filters can be purchased direct from
Nuaire using the following code 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.
Note: 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.
12.4 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 20-30 seconds then
release, 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.
12.5 Binding a 4 Way Switch
Once the fan unit is in binding mode a switch may now be bound.
• Press and hold the ‘Boost’ & 'Heater off' button for 2-5 seconds.
• The LED will flash GREEN twice when bound.
To check the 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).
The switch is provided with an adhesive foam pad to allow quick and easy
mounting to the wall. Alternatively the switch may be mounted to the wall using
the fixing plate (screws are not provided).
Remove the switch fixing plate by inserting a flat head screwdriver in the rear of
the switch on the left or right side, underneath the fixing plate and gently lever
up the plate until the fixing lug releases. Repeat for the opposite side. This will
give access to the battery compartment on the rear of the PCB and release the
fixing plate. Reassemble the remaining components and press into place, an
audible click will be heard. 1x CR 2032 battery is provided and expected lifetime
is 10 years under normal use.
Normal - If the normal button is used the unit will return to its standard
operation programmed at the diffuser.
Boost (Purge) - If the boost button is used, the fan speed will increase to
maximum and a ‘P’ will be shown in the display.
Heater auto - If the heater auto button is used, the heater switches on/off
automatically as needed.
Heater off - If the heater off button is used 'Heater auto' will be disabled and
the heater switches off.
The CO
2
sensor requires a 230V power supply. Remove the front panel as per
the humidity sensor above and release the terminal cover via a fixing lug on the
rear of the sensor. Refer to the wiring diagram below and connect the supply to
the terminal box. Finally the sensor may be mounted to the wall (screws are not
provided).
12.6 Binding a Sensor
Putting the unit into binding (see 12.4) 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 (see 12.4).
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.
12.7 Setting the 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.
The front panel of the sensor must first be released by pressing in the plastic
fixing lug located on the bottom edge of the sensor. The panel may now be
removed and the sensor mounted on the wall in a suitable location (screws not
provided). 2x AA batteries are provided.
