2.1 Binding Unit To Sensor
2.1.1 Unit Binding Mode
Where a Humidity sensor is present, it must first be bound to the fan
unit before it can work. In order to bind the sensor(s) the fan must be
in binding mode. The steps required to enter binding mode are shown
below.
•
Ensure the fan unit is powered on.
•
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.
•
Press and hold the both the UP and DOWN buttons for 20-30
seconds then release. A single horizontal bar on the display flashes.
•
Press "down" to enter binding mode (binding mode lasts for 5
minutes).The unit will now display a flashing ‘b’ to indicate it has
entered binding mode.
A solid “P” indicates purge, a solid “b” indicates boost, and a
flashing “b” indicates binding mode.

2.1.2 Binding Sensor
Putting the unit into binding mode (Section 2.1) before powering the
sensors will automatically bind the sensors to the unit. However if they
do not bind follow the below steps.
•

•
Power up sensors (insert batteries for humidity, mains for CO2).
•
Tap indented button then hold until left hand LED flashes red/
green (ignore red/blue and continue to hold). Release button
whilst flashing.
•
Tap indented button again, whilst red/green LED is still flashing.
•
Close binding window on fan control panel by holding both “up”
and “down” for 5 seconds and release.
•
Check sensor has bound by tapping indented button and look for
left hand LED to go green. If it displays red, repeat from step 1.
2.2 RF Frequency
RF enabled DRI-ECO devices operate at a frequency of 868.3 MHz.
3.0 CONTROLS
3.1 Sensor Setpoint
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 until the status indication LED flashes
BLUE/RED then 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 to confirm choice. If the button is not operated for
10 seconds the set point currently selected is stored.
Boost (Sensor) -
If a sensor set point has been exceeded, the unit will
enter boost mode and a solid ‘b’ will be shown in the display. Boost
mode increases the speed setting by 1. If the unit is running at speed
6, boost is ignored (i.e. A unit is running at speed 3. A boost signal is
received from a sensor whereby the speed changes to 4. When the
boost condition clears, the unit will revert to speed 3).
3.2 LED Indicators
The sensors and switches include an LED which illuminates when a
button is pressed. A green light shows that communication between
the sensor or switch and the fan unit is taking place. A red light shows
that no communication is taking place and binding may be required.

It is important that maintenance checks are recorded and that the
schedule is always adhered to, in all cases, the previous report should
