MRV Application

The EV3 MVC and EVD MVC are controllers for mechanical ventilation units for air renewal and handling, capable of complying with the most rigorous standards for air-quality and building energy certification. Independent control of the supply and extraction fans, both EC modulating and multi-speed types, makes possible optimum flow distribution in all situations. Environmental comfort, in terms of temperature and humidity, is achieved by the ability to manage different heat recovery systems, with free-cooling and free-heating functions, and sources of heating/cooling.

The MVC solution is available in both the compact EV3 version (12 VAC and panel installation) and the split EVD version (115... 230 VAC and DIN rail installation). In both cases it is possible to connect, according to your needs, the stylish EVJ LCD remote user interface (wall-mounted) or the EV3K11 reduced-depth interface (panel fitting).

With 6 capacitive keys and an optional Bluetooth BLE communication module, EVJ LCD provides end-users with easy, intuitive control of the unit using the EVcontrol APP for iOS platforms, transforming your smartphone or tablet into a state-of-the-art remote control.
