SETUP
Accessing the commissioning menu
To configure the fan first remove the grille. With the grille removed the control buttons
are visible (Fig.4). 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.4). 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 initialisation 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

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 (CV model only, other models display speed setting)
Estimated duct pressure (CV model 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
