EV HRV

EV HRV

Controllers for heat recovery ventilation units
EV HRV is a series of controllers with ready-to-use application software for energy-efficient heat recovery ventilation units for air renewal and handling.
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 heat recovery systems, with free-cooling and free-heating functions, and sources of heating/cooling.
The solution is available in the following hardware formats: - EV3 (74x32mm) with built-in LED display, capacitive touch keys, IP65 front protection, 12 VAC power supply and panel fitting; - EVD (4 DIN modules) in blind version or with built-in LED user interface, 115... 230 VAC power supply and DIN rail installation. Both formats can be connected, according to your needs, to the stylish panel- or wall-mounted interface EVJ LCD or to Vled 3, a reduced-depth interface for 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 Android and iOS platforms, transforming your smartphone or tablet into a state-of-the-art remote control.
Upon request, the controller can be equipped with Wi-Fi connectivity so it can interact remotely with the unit through the EPoCA® cloud platform.
