About this app
APP for controlling your O.ERRE heat recovery units
O2 is able to configure and control the O.ERRE heat recovery units installed inside your home in a simple and immediate way even if you are far from home.
The various recovery units can be configured in a simple and intuitive way so that they behave as a single ventilation system or can be managed as individual ventilation units.
The configuration and control of the units can be done either via 2.4GHz WI-FI or via Bluetooth if there is no internet connection inside your home, in which case some of the product's functions will be limited (in this case, refer to the product's instruction manual).
With O2, numerous operating modes can be set: Automatic, Manual, Surveillance, Night, Free Cooling, Extraction, Timed expulsion and up to four air flow rates.
O2 monitors air quality through an humidity sensor on board and automatically decreases the fan speed during the night to ensure the best possible comfort (function active in Automatic and Surveillance modes).
O2 is compatible with O.ERRE heat recovery units that have the "02" ending in the product name.
