Product overview
The Samsung MA duct indoor unit AJ052BNMDEG/EU is a compact ducted air handling solution for HVAC installations where concealed installation and flexible air distribution are required. The unit offers selectable fan operating ranges and multiple service access points to ease integration and maintenance in commercial and light-industrial applications.

Features

• Ultra-compact design: suitable for installation in limited ceiling voids; certain larger models (20/25 kW) can be split into two parts for simplified installation and servicing.
• Comfort control: indoor discharge temperature management for both cooling and heating via remote control; compatible with ducted systems or AHU-connected setups.
• 3-way service access: slide-fit cover allows maintenance from top, side or bottom to accommodate varied installation constraints.
• Automatic External Static Pressure (ESP): enables selection of an optimal fan operating range to balance sound level and capacity; straightforward to configure on site.

Smart control
Remote temperature control is available via the SmartThings App (requires Wi‑Fi kit). Supported functions include remote on/off, mode selection, scheduling and energy monitoring. Voice control via Bixby 2.0 and Google Assistant is supported where available.

SolarCell Remote Controller (optional)
Optional SolarCell remote provides integrated solar charging (no disposable batteries), USB-C fast charging, slim form factor and a large OLED display for improved usability. Under typical use a full charge can last up to two years.
