Panasonic Aquarea Air Smart P-FSN55O05-JE Ducted Fan Coil Size 55 – 0-10V PCB, Left-Hand Piping, 240mm
Hurry up, only 10 items left in stock.
The Panasonic Aquarea Air Smart P-FSN55O05-JE is a size 55 ducted fan coil unit with 0-10V analogue PCB control and left-hand water connections – the larger-capacity concealed option for distributing heat pump heating and cooling through ductwork.
With a 240mm profile the ducted unit suits deeper ceiling voids and plant cupboards, installing horizontally or vertically. A DC inverter fan with a single-motor centrifugal impeller runs quietly, and self-modulating airflow control continuously matches output to the room for maximum energy savings alongside an Aquarea heat pump.
Water connections are on the left-hand side of this model. Optional 2-way or 3-way motorised valves (PCZ-V20139, PCZ-V30361) complete the hydraulic side, and control is via 0-10V analogue input on the PCB, for BMS or third-party thermostat integration.

Specifications
Compact and lightweight design
With a low weight of just 21 kg, this ventilation unit can be installed quickly and safely by a single installer. Its space-saving footprint makes the DucoBox Energy Comfort perfectly suited for small plant rooms and confined technical areas.
Software-controlled left/right configuration
The unit is designed for maximum installation flexibility. Left- or right-hand airflow orientation is adjusted entirely via software, eliminating the need for mechanical modifications. This is made possible by an innovative patented double bypass system.
Automatic calibration
Using constant pressure calibration technology, the AUTO calibration function reduces commissioning time by up to 50%. In real-world installations, this can translate into lower labour costs and faster system setup.
High energy efficiency
Advanced dynamic air filtration ensures consistently high heat recovery efficiency. When combined with optional intelligent demand control based on CO₂ and humidity sensors, the system delivers excellent indoor air quality while minimising energy consumption.
Smart copy function for fast commissioning
An integrated software-level copy feature allows installers to duplicate settings and parameters from one unit to another. This is especially valuable for multi-unit or repeated housing projects, ensuring consistent performance and significantly reducing setup time.
