7.6 Anti-frost functionality
The unit is equipped with a thermostat which, when necessary, reduces the speed of the intake fan to prevent the freezing of the heat exchanger, which could

7.7 Bypass functionality
The QR350MBP is equipped with a physical bypass which allows to mitigate the heat exchange when the indoor and outdoor temperature combinates are
such that the heat exchange is not recommended.
