1 INTRODUCTION
EV3 MVC and EVD MVC are controllers for the management of mechanical ventilation units for air renewal and handling, capable of
complying with the most rigorous standards for air-quality and building energy certification.
Independent management 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 recovery heat exchangers, with free-cooling and free-heating functions, and sources of heating/cooling.
EVCO offers the MVC solution 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 the stylish EVJ LCD remote user interface, it is easy to install (wall-
mounted) and it can be integrated into any environment.
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 Android and iOS platforms, transforming your smartphone or tablet into a state-of-the-art remote
control.
