Facade Fan Coil Unit Type FVD for floor installation with decentralized outside air supply via the facade, for heating and cooling Application The Facade Fan Coil Unit type FVD is a 4-pipe unit for the decentralized ventilation of occupied rooms (outer zones) via the facade using outside air, including cooling and heating. It is perfect for installation in false floors with an overall unit height of at least 203 mm when using floor panels (38 mm) with covering (8.5 mm) and a minimum height of 175 mm when placing the floor covering directly on the ventilation module. Since all components are below...

Facade Fan Coil Unit Type FVDplus for floor installation with decentralized outside air supply via the facade, recirculating air mode, for heating and cooling Application Functional Principle The FVDplus has the same functions as the FVD but, additionally, includes a tangential fan used to recirculate room air and increase capacity in the fresh- air mode. - The FVDplus allows for three different operating modes: 1. operation with fresh air intake only (the same as FVD) 2. operation as a recirculating air unit without outside air intake 3. operation with fresh air intake and recirculating air....

Facade Fan Coil Unit Type FVD/FVDplus - Advantages Advantages Direct Induction The heat exchanger heats/cools room air and outside air which results in: increased heating and cooling output due to increased flow rate better protection against freezing better thermal comfort effective use of free cooling excellent room air flow with air diffusion close to the facade and mixed/displacement air flow. FVDplus: High performance due to mixed in room air and recirculating air fan Fast air conditioning due to increased output. Fast cooling/heating of completely cooled rooms. Ideal supplement to slow...

Facade Fan Coil Unit Type FVD/FVDplus - Installation Example Room Facade FVD Installation example: Continuous grille along the facade, facade fan coil unit FVD and aluminum roller grille Facade fan coil unit FVD after installation with cutout floor boards If the look of a continuous grille along the facade is required units are screw connected using matching black coated distance sheets. In case of end pieces and if the spacing is more than 400 mm supports will have to be used for stabilization. The LTG aluminum roller grille also allows for production of cutouts for columns and mitre edges....

Facade Fan Coil Unit Type FVD - Electrical Connection An error message may be applied to the terminal box. The message will be displayed in case one of the following conditions occurs: Electrical Connection The unit is provided with connecting cables equipped with connector sleeves. Electrical connection is made, on site, via a terminal box mounted to the unit (protection IP66). - the fan does not run, irrespective of load applied Available are 3 outside air flow rates which may be triggered directly via a control line. This control line has an outside air flow- dependent voltage of up to mains...
