Comfort throughout the year
The ATTACK cassette fan coil distributes air in four directions. In a two-pipe heat pump system, it can provide both heating and cooling; ten FCU-C models cover an output range from 2 to 24 kW.

Year-round use
With its four-way outlets, the unit can serve larger spaces while distributing air evenly throughout the room. In family homes, cassette units usually require a lowered ceiling to conceal the working section. Only the visible panel remains below the ceiling, with adjustable louvres controlled by remote.

Airflow
The difference between cassette and wall-mounted units is the direction and distribution of air. A cassette unit distributes air in all directions at lower intensity, while a wall-mounted unit directs the full airflow in one direction.
Remote control
The heat pump can supply hot or chilled water to the fan coil through the heating system. In summer, when hot weather can make indoor spaces uncomfortable, the fan coil helps maintain a comfortable temperature. In winter, its low running costs can make it a more efficient heat source than radiators.
Quiet operation
The fan motor’s position and vibration damping help keep operation quiet across the three fan speeds.
ATTACK FCU cassette unit options
The cassette unit transfers heat or cooling from a heat pump into the room and is installed in a suspended ceiling.
The remote control offers several programmes with timer settings. You can schedule the fan coil to cool or heat at a specific time, for example to cool the house before you return from work. Use the remote to adjust the intensity and direction of the heating or cooling airflow. A fixed wired wall controller can also be installed.
Detailed specifications
Test conditions: two-pipe system. For cooling, entering air is 27 °C dry-bulb / 19.5 °C wet-bulb and water is 7/12 °C. For heating, entering air is 21 °C and water is 60 °C; water flow is the same as for cooling. Noise and electrical input are stated at high fan speed and 0 Pa static pressure.
