Roomie Dual provides balanced ventilation with heat recovery in single rooms. The unit’s two fans continuously provide balanced supply and exhaust air. Heat energy is recovered from the exhaust air in a ceramic heat exchanger, providing tempered and filtrated supply air. An electrician is not required, since the single room ventilator is supplied with assembled cable and plug. During warm periods, the ventilator can be set to ventilation mode for ventilation without heat recovery. Roomie Dual Wifi can be installed in wet rooms; the unit has filter warning, humidity sensor, and timer functions.
