WIRING.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM THE POWER SUPPLY DURING INSTALLATION OR MAINTENANCE.

IMPORTANT

• The cross – sectional area of supply cord used should be ranged from 0.75 – 1.5mm2.
• Cable entry can be made from the rear or on 100mm models also the side of the fan using the grommet provided.
• The extraction fan or transformer (SELV models) is suitable for connection to 220-240V 50Hz supply.
• The Transformer (SELV models only) MUST be surface mounted to allow air to freely circulate around the unit. When installed in a loft void it MUST NOT be enclosed or covered with insulation.
• The fan is a class ll double insulated product and MUST NOT be earthed

1. Select and follow the appropriate wiring diagram. (Fig. 1, 2, 3, or 4, 5, 6)
2. Check all connections have been made correctly and ensure all terminal connections and supply wires are securely fastened. (Fig. 7)
3. Ensure the impeller rotates and is free from obstructions.

SETUP

Accessing the commissioning menu
To configure the fan first remove the grille. With the grille removed the control buttons are visible (Fig.7). Do NOT isolate the fan from the power supply as configuration requires power to the fan

IMPORTANT
Do NOT attempt to remove the circuit board cover ( Fig.7). This covers the high voltage power supply, preventing the risk of an electric shock.

Display modes
When first powered on, the display will run through an initialization sequence and then activate prism mode (cover on).
When a button is pressed, the display will go into the menu system and display as viewed without the prism.
The display will return to prism mode after 30 seconds of inactivity (i.e. no button presses).
When activating the menu, the initial button push will not change any settings.
Prism mode may also be re-activated by holding the pull-cord for 5 seconds (if applicable).

Prism Mode
When the controller is in ‘prism mode’ the display will be mirrored such that the characters are shown correctly when viewed through the prism fitted in the fan cover.
When activated, prism mode will run for 15 minutes, first showing the day logger then cycling between displaying:

• Airflow rate (Pro models only, other models display speed setting)
• Estimated duct pressure (Pro models only if CV / F‐2 mode enabled)
• Current RH% (HT models only)

Calibration process will run after the first 15 minutes (if CV / F-2 mode enabled); see Advanced settings for further details.

Menu
If the buttons are pressed the display goes from prism mode to direct view mode and menu activated. If the buttons are not pressed for 30 seconds the display reverts to prism mode.

The (Up) button is used to increase the value of a setting, the (Down) button is used to reduce the value of a setting and the (Mode/Set) button is used to advance to the next menu item.

The fan has the following ‘menu’ modes:

• Standard (press any button from normal runtime – )
• Advanced/Engineer (hold + for 5 seconds from the standard menu)
• Data-logger readout (hold for 5 seconds from standard menu)

Standard settings:

15
| Humidity level trigger| h40 to h90 ‐ 40% to 90% relative humidity| 70% RH
| Fan Control Mode| F‐0 = CV disabled, wall / window installation| F‐1 = CV disabled, ducted installation| F‐2 = CV Constant Volume enabled| F‐0
| Comfort mode| c‐n = normal LS overrun| c‐Y = comfort mode| c‐n
| Enable / disable lock code| loc ‐ lock code enabled| unl ‐ lock code disabled (unlocked)| unl
| **** Menu lock code| Up / down selects current digit, X moves to next digit.| 10c
****| To change the lock code when “cod” is displayed select the up/down buttons to select a digit then select X to move on to the next digit.

*If “0” is selected, the fan switches to Intermittent mode.

Settings

Speed selection
Set trickle and boost speeds in l/s by using the and buttons. To convert m3/h to l/s, divide the m3/h by 3.6 (e.g. 54m3/h / 3.6 = 15 l/s). The Trickle Speed cannot be higher than the Boost selection. Therefore it might be necessary to modify the Boost selection before increasing the Trickle setting.

If “0” is selected for the trickle speed, the fan will be off until a boost signal is activated (for example via LS/ pullcord/humidity).

Boost time
The boost setting allows the boost timer to be adjusted from 1-30 minutes, the default is 15 minutes. This option may also be disabled, thus removing the option from the menu and setting the overrun to 0.

Inbuilt Ambient Response Humidistat with Rapid Rise Detection
The humidity threshold setting defines at what relative humidity the fan will trigger, adjustable from 40% to 90% rH. The fan increases in speed slowly between the trickle and boost speeds between the trigger %rH and +10%. The trigger point will automatically adjust if the temperature drops below 18C to prevent nuisance triggering.

The fan also incorporates a rapid rise function to detect rapid rises in humidity when the ambient %rH is under the threshold setting. If a rapid rise is detected the fan will increase in speed proportionally between the trickle and boost settings until the humidity lowers again

Comfort mode

• With comfort mode disabled, the fan will go into boost as soon as an LS (Light Switch) input is detected and over-run for the set period after LS is disconnected.
• With comfort mode enabled, the fan will remain off / in trickle up to a maximum of 20 minutes. Once LS is deactivated, fan will run at boost mode for the length of time LS was present up to a maximum of 20 minutes plus the set over-run time.  If the LS was activated for < 3 minutes, no boost will occur toprevent nuisance activations.

Fan Control Mode
There are 3 modes for fan speed control. Wall, ducted and constant airflow/ volume (CV) mode (CV – Pro models only). In wall or ducted mode, the fan speeds are pre-determined at the factory and does not use the airflow sensor.
In CV mode (Constant Airflow/Volume), the fan will automatically adjust the fan speed to maintain the desired airflow. After the first 15 minutes of operation the fan enters calibration mode to determine the most efficient mode of operation.

Calibration Reset
In some circumstances it may be necessary to reset the calibration settings (if the fan was covered to prevent dust/damage/or poor weather outside).
Reset the calibration by configuring the fan for wall or duct mode ( F-0 or F-1) , turn the product off and on and re-configure back to CV mode ( F-2 ). The fan will calibrate after 15 minutes or by holding the pullcord for 5 seconds.

Pullcord

• Switches the fan from trickle to boost (for boost overrun time)
  •  If the overrun time has been set to 0 (disabled), a default overrun duration of 5 minutes will take place.
• This will override LS comfort mode, boosting the fan immediately
• An activation when a Pullcord/LS (Light Switch) boost is already active shall cancel overrun timer (RH boost sources remain unaffected)

Data Logger Menu

• When the display is rotated the decimal point will no longer display; eg. 055 represents 5.5KWh

Cutting the power to the fan will not erase the stored data. To reset the data, hold pullcord for 14 seconds while in the data logger menu

Data Examples
Text scrolling from right to left In this example the display is showing a total run time of 1 year and 237 days

Text scrolling from right to left In this example the display is showing 34Wh of energy consumption in the previous 24h.

Returning to commissioning mode
A further 5 second press of the Mode button will return the fan to the commissioning menu.
