Midea Wall FCU Left Right or Rear Piping 0 10V BMS Input 10W Low Speed 27 dB Quiet

Some buildings cannot accommodate a concealed terminal at all: heritage conversions, mid-rise walk-ups, budget hotels and school blocks built without suspended ceilings. A wall mounted fan coil is the only viable option in those cases, and it is usually specified late, under pressure, and without the coordination attention the rest of the system received. The Midea Wall Mounted Fan Coil Unit is designed to be specified properly in that situation — left, right or rear water connections match wherever the existing risers actually run, the unit mounts directly to the wall with no ceiling interface, and the family covers 300–600 CFM and 1.94–4.87 kW of cooling across the combined AC and DC range, with Eurovent-certified performance behind the selection.

The internal design is aimed at the criteria a design engineer is asked to defend: a cross-flow fan and two-row coil in a body that mounts without penetrating the ceiling membrane, G1/2"–G3/4" connections and a 1.6 MPa maximum working pressure inside normal practice, and sound pressure from 30 dB(A) on AC and from 27 dB(A) on DC — the band that makes a guestroom or consulting room submission credible. The oscillating louver addresses draught complaints at the design stage rather than after handover, the display shutoff keeps sleeping areas dark, and the front panel removes without tools so the maintenance strategy does not depend on a specialist visit.

Controls are where this unit is most often underestimated: 0–10V input and output is built in for direct integration with a building management system, which suits a schedule written around analogue modulation, and Hongtai supports OEM/ODM control protocols including Modbus RTU and BACnet where the specification calls for them. The DC inverter brushless version draws 10W at low speed and reduces fan energy by up to 30%, with seven speeds through the KJR-75A controller for room-by-room balance. Two panel designs, A Type and P Type, allow the interior finish to be resolved without changing the terminal unit behind it, and all models run on 220–240V / 1Ph / 50Hz.

• No Ceiling Interface — The terminal mounts directly to the wall, so buildings without suspended ceilings can be served without altering the structure or the finishes.
• Left, Right or Rear Piping — Three pipe orientations within one unit, so the riser position does not dictate the equipment selection.
• 0–10V Input and Output as Standard — Direct analogue integration with a building management system, with Modbus RTU and BACnet available through Hongtai for protocol-based schedules.
• From 27 dB(A) on the DC Tier — Supports guestroom, consulting room and classroom acoustic criteria without secondary attenuation.
• 10W at Low Speed (DC) — Up to 30% lower fan energy, which matters where rooms run continuously.
• Cross-Flow Fan with Two-Row Coil — Even discharge across the room face with a coil depth that suits standard chilled and low-temperature hot water.
• A Type / P Type Panels — The interior finish is resolved without a change to the terminal unit, the connections or the schedule.
• Tool-Free Front Access — Filter service is a short visit rather than a maintenance event, which protects the O&M strategy.
• AEH Option 750–900 W (AC) — Electric auxiliary heating where the heating source is not water-based.

Where rooms are occupied for a few hours a day and the schedule is capital-cost driven, the AC three-speed version meets the duty with the simplest control interface. Where the space runs continuously — guestrooms, serviced apartments, dormitories — the DC inverter brushless version is the better case: 10W at low speed, up to 30% lower fan energy and 27 dB(A) at the quiet end, all with the same wall-mounting method, the same three piping directions and the same panel options. Because the mounting and hydraulic interfaces are identical, the motor decision can be taken at tender stage without revisiting the wall and riser coordination.

1. Heritage and Conversion Projects — Comfort delivered where ceiling alteration is restricted by structure, consent or listing.
2. Budget Hotels and Serviced Apartments — Fast installation and low DC running cost suit thin-margin hospitality operation.
3. Residential Walk-Ups and Mid-Rise Blocks — Surface mounting serves apartments with no suspended ceiling provision.
4. Classrooms and Dormitories — Robust, low-maintenance terminals for institutional occupancy patterns.
5. Clinics and Consulting Rooms — Wall mounting avoids penetrating ceiling membranes in clinical and diagnostic spaces.
