Overall dimensions
The fan has four ventilation modes:
1. Standby mode - standard operation mode for the fan in case of no signalling from the sensors or external switch.
In standby mode the fan does not run.
2. 24 Hours - the fan runs at low speed for minimum round-the-clock ventilation. As temperature set point is crossed, the fan
switches to MAX mode (by default) or to SILENT mode. The fan switches to SILENT mode when the external switch is closed.
3. SILENT - silent operation mode of the fan. This mode is may be activated by the external switch or after corssing the
temperature set point. For temperature sensor, this mode may be activated from the fan.
4. MAX - temperature-activated operation mode. It is switched on as temperature set point is crossed.
This mode is activated for the temperature sensor by default.

Control panel
You can adjust the fan both with the control panel located on the fan or with the remote controller.
The remote controller has 3 m effective range. To attain the maximum effective range response direct the remote controller
straight to the fan.
WARNING!
The fan covers of Melange, Ruby Star, Champagne, Silver colours provide high signal conductivity from the remote controller and
do not influence the signal transferability.
The covers of Graphite, Violet Topaz or Black Sapphire may suppress the signals.
To avoid this, please remove the front cover during adjustment operations.
After each signal reception the fan sends an acoustic signal to confirm the setting adjustment. In case of no acoustic signal
from the fan try to press a button on the controller once again or come nearer to the fan.
6RC button is deactivated on the remote controller (available for the model iFan Move).

(temperature fluctuations or activation by the external switch). The interval ventilation function remains activated and in
15 hours the fan switches on to ventilate a premise for 2 hours.
EXTRA MODE - INTERVAL VENTILATION
Automatic function. It can not be adjusted or turned off. After 15 hours standstill the fan is switched on for 2 hours to ventilate
the room with air capacity 83/72 m3/h. If the fan receives a signal from the temperature sensor or in case of the external switch
