1INTRODUCTION
1.1 Preliminary notes
The c-pro 3 OEM HRV programmable controller has been designed for the advanced management of mechanical ventilation units to renew and treat air in household
settings. It complies with the increasingly stringent regulations governing air quality and energy certification in buildings.
The independent management of the input and extraction fan (both EC and varied speed types) allows for the best flow in any situation.
Room comfort is achieved by the management capabilities of different types of heat exchangers (with free cooling and heating) and heating/cooling sources.
The BLE module integrated in the EVJ LCD interface provides the end user with easy, intuitive control of the unit, thanks to EVcontrol PP for iOs and ndroid platforms
which transforms your smartphone or tablet into a sophisticated remote control.
