Grand fan coil unit

Technical information and manual

Draught-free and silent fan coil unit

The Grand fan coil unit is designed for through wall installations. The typical applications for the Grand fan coil unit include hotel rooms and different types of residential buildings. The innovative dual direction grille solution guarantees draught-free, silent and uniform temperature indoor air. Cooled or heated supply air and fresh air are directed from the upper side of the grille to the room, and the air is returned back to circulation through the downside of the grille. The supply air is directed along the ceiling to guarantee the draught-free cooling.
Especially designed for optimum performance with EC-fans, the grille solution guarantees draught-free and silent cooling with minimal energy consumption. The thermal transfer area of the coil has been optimized to ensure maximum cooling power.
The preferred sound level of the unit can be selected from five standard options. The fan performance is continuously variably optimized within the sound limits.
The Vari Pro automation controls the air temperature and fluid flow precisely and accurately.  The units are configured at the factory according to the site’s demand and tested with a dedicated test system.

Fast to install

The Grand fan coil unit is installed for example to the solid ceiling surface of the hallway. Only an opening for the grille is required for the cooled or heated room. All external connections are located to the back side of the unit, reducing the need for maintenance space, and making the installation and maintenance fast and easy. Plug connection guarantees easy electrical connectivity without additional electric work. The connection to a modbus building automation system is established via VariPro room controller. The VariPro room controller comes with a cable and fast connector for easy installation to the unit. The room controller’s commissioning tool, “Start Up Wizard”, guarantees easy and fast commissioning and testing. The installation which used to take up to several hours of installation time is reduced to only half an hour. The fan filter can easily be accessed for cleaning by opening the grille. Also, the condensate pan of the unit can be detached for washing.
