Standby mode
Waiting mode of the fan with no signalling from the sensors
or external switch / pull-cord switch. In standby mode the fan
is either stopped or has low-speed operation to ensure
minimum airing. The standby mode speed is adjustable from
the control panel.
Active mode
Operation mode of the fan when either motion sensor,
pull-cord or external switch is activated.
The fan switches to higher speed and operates at higher speed
within set time period to remove odours.
