INSTALLATION
Installation must be completed by competent persons, in accordance with good industry practice, and should conform to all governing and statutory bodies i.e. IEE, CIBSE, etc.
The CO2 sensor requires a 230V power supply. The front panel of the CO2 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 allowing access to complete the sensor wiring. Finally, the sensor should be mounted on the wall in a suitable location (screws not provided).

Binding Unit To Sensor
Where a CO2 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.
Unit Binding Mode
The steps required to enter the unit into binding mode are:
- Ensure the fan unit is powered on.
- The 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 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 the binding mode.
A solid “P” indicates purge, a solid “b” indicates boost, and a flashing “b” indicates the binding mode.
Drimaster Diffuser Control
Binding Sensor
Putting the unit into a 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.
- Put the unit into binding mode.
- Power up sensors (insert batteries for humidity, mains for CO2).
- Tap the indented button then hold until left hand LED flashes red/ green (ignore red/blue and continue to hold). Release button whilst flashing.
- Tap the indented button again, whilst the red/green LED is still flashing.
- Close the binding window on the fan control panel by holding both “up” and “down” for 5 seconds and release.
- Check sensor has bound by tapping the indented button and looking for left hand LED to go green. If it displays red, repeat step 1.
RF Frequency
RF-enabled DRI-ECO devices to operate at a frequency of 868.3 MHz.
CONTROLS
Sensor Setpoint
The sensors will automatically trigger the fan to increase speed once the sensor set point has been exceeded. To change the sensor setpoint, 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 the choice. If the button is not operated for 10 seconds the setpoint 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).
LED Indication
The sensors and switches include an LED that 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.
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.
Routine Maintenance
This sensor can be cleaned with a dry brush or dry cloth. Any other
maintenance or cleaning should be carried out by properly qualified personnel.
Ensure the unit does not come into contact with any kind of liquid or solvent.
If this should occur, contact a qualified technician before reassembling the
fan.
