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.
