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
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)
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.

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

a setting, the (Down) button is used to reduce
the value of a setting and the (Mode/Set) button
