Power Key
The Power key switches the IQAir® ystem on and off. When the system is switched off, the fan stops to run, but
the system will remain connected to the power supply (standby mode). The standby mode allows for automatic
timer start-up. In the standby mode, the different menu functions can be accessed.
Tip: In a menu window the Power key also serves as a quick exit key to return to the main display window.
Arrow (p) Key
When the system is switched on, the p key allows the adjustment of the fan speed. In the enter mode,
indicated by the appearance of a black ashing cursor (see “Enter Key” below), the p key is used to modify the
selected setting in the display window. Conrmed with the Enter key, the enter mode is automatically terminated.
The LCD will then display the current menu settings for another 15 seconds before reverting to the main window
display.
