Overview: The document details the engineering specifications of Aqu@Fan II fan coil units, emphasizing their innovative design, high performance, and quiet operation. These units are versatile for various installations, including vertical and ceiling-mounted configurations, with options for exposed or concealed units.

Specifications: The fan coil units come in multiple models tailored for specific installations: vertical console units (AWC), vertical concealed units (AWN), ceiling exposed units (AHC), and ceiling concealed units (AHN). They feature a modern design with optional controls and accessories, such as the Aqu@Net electronic control system.

Design Features: Constructed from heavy-gauge zinc-coated steel with an epoxy paint finish, the units include high-efficiency coils made of copper tubes and aluminum fins for optimal heat transfer. The fan and motor assembly is designed for low noise and optimal air volume, featuring a 5-speed motor with thermal protection.

Options and Accessories: Available options include auxiliary drain pans, support feet, air intake grilles, and motorized or manual dampers. Customization is possible with different air intake arrangements and control systems.

Dimensional Data: Detailed dimensions and weights are provided for each model to aid installation planning, along with diagrams illustrating configurations and connections for water and condensate drainage.

Performance and Control: Aqu@Fan II units offer improved sound levels and performance, with air flows from 100 to 1600 m3/h and cooling capacities from 1 to 10 kW. The Aqu@Net control system includes advanced features like master/slave functionality, window contact, and antifreeze modes for enhanced user convenience and system efficiency.

Valve Specifications:

• 4-way Valve: Designed for 2-pipe systems on cooling or heating coils, available with a thermal actuator of 230 V or 24 V, operating at 50/60 Hz. Sizes range from 1/2" to 3/4" with a maximum ambient temperature of 50 °C and fluid temperature of 110 °C.
• 2-way Valve: Also for 2-pipe systems, available with a 24-Volt actuator, with similar size and temperature specifications as the 4-way valve.

Electric Heaters: Available in multiple configurations with power outputs ranging from 200 to 4000 watts, suitable for Aqu@Net control.

Aqu@Fan II Performance Data: Includes detailed performance metrics for various unit sizes and speeds, covering air flow, cooling and heating capacities, sound levels, and water pressure drop, based on specific summer and winter conditions.

Main Controls:

• Manual Fan Speed Selector: Offers four positions: OFF, LS, MS, HS.
• Thermostat Options: Includes wall-mounted remote thermostats and electronic controls for various system configurations.
• FCC Electronic Controller: Configurable for different system types, with functionalities like master/slave control, antifreeze mode, and remote control options.

System Networking: Utilizes RS485 communication bus for monitoring up to 100 fan coil units, with capabilities for daily and weekly programming, temperature setpoint adjustments, and operation mode selection.

Technical Data: Provides air flow rates and electrical data for different unit sizes and speeds, highlighting maximum absorbed power and current.

Note: Products are subject to change as part of ongoing improvements.
