INTRODUCTION
EV3 HRV and EVD HRV 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 management of the supply and extraction fans, 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.
EVCO offers the HRV 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, 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 and Android platforms, transforming your smartphone or tablet into a state-of-the-art remote
control.
Fully protected by a white list, your mobile device becomes a handy tool for adjusting the function mode (heating/cooling), temperature
and humidity set-points, fan speed and timer settings. Any alarm events are displayed in real time and can be sent directly to your
assistance centre.
EVcontrol is compatible with Android 4.4 and iOS devices, with Bluetooth 4.0 (BLE) or later versions.
