2 REVERSUS Residential ventilator unit with dual flow and high yield heat recovery. PERFORMNCE Equipped with a counter current heat exchanger in thermoplastic material (polystyrene) and electronic backward blade ventilators. The total bypass as standard allows favourable climatic conditions to be taken advantage of outside the building for free cooling (or free heating) in automatic mode. STRUCTURE REVERSUS is manufactured using a self-supporting structure in 23 mm thick sandwich panels, insulated in polyurethane foam. The external t part of the structure is manufactured in plastofilmed sheet metal in grey, while the internal part is in luzinc, material that ensures high resistance against corrosion. Inside, REVERSUS is in expanded polypropylene, material that ensures a high level of thermal insulation between air flows. The access to filters (F7 for the renewed air flow and G4 for the extraction air flow) is particularly easy thanks to the two specific openings on the front panel. REVERSUS, is also available in enthalpy version. Is prepared for installation inside buildings with an ambient temperature between C and 45 C. It can be installed on a wall with connections for renewal air and expulsion on the upper part; for connections to supply and extraction ducts, you can choose to use the connections available on the top or bottom of REVERSUS (or both). CONTROLS REVERUSUS was supplied with an electric box and control system; it is available in a version equipped with EVO-PH control and a version equipped with EVOD-PH-IP control prepared for complete integration in home automation systems (Modbus protocol with Ethernet connection or, on request, with the addition of connection RS485). The new version of our control systems enables extremely easy and rapid passage from a control system to another, even after installation with the single replacement of the remote panel. The EVO-PH control has a coloured, backlit touch screen interface with intuitive viewing of the working status of the machine. It enables precise adjustment of ventilator speed and has a weekly, time schedule for automatic management of the ventilators. It can be controlled by an external switch to activate the booster function, it can automatically adjust the air flow rate if connected to an air quality probe, it can manage any air post treatment accessories, it automatically manages the bypass and prevents heat exchanger freezing by managing the speed of the ventilators or, if installed, an electrical pre-heating resistor (optional accessory outside the machine); it signals to the user the need to replace the filters (the clogging status of the filters is monitored by a pair of different pressure switches, supplied as standard) or an anomaly, indicating the origin. With the addition of optional accessories (COP kit and CV kit installed on the channel) you can manage the ventilation machine in constant pressure or constant flow rate mode. The EVOD-PH-IP control has the same characteristics as the EVO-PH version with the addition of Modbus communication protocol which allows full control of the machine by the supervision software of the home automation system. The implemented webserver allows interaction with the machine, even with an internet browser of a device connected (even from remote) to the home automation system in which the machine is inserted. For a more complete view of the characteristics of the control panels, please read the specific manuals 2
