Smart Features
Features that make everyday life more comfortable, efficient, and safe.
Static pressure adjustment
Static pressure can be adjusted via the wired control for better performance.
Fresh air intake
The Fresh Air function ensures a cleaner and more pleasant feeling in your space.
7 fan speeds
Offering complete control over air flow and adaptation to the comfort needs of every space.
Dry contact testing
The air conditioner supports control via dry contacts, allowing it to be automatically turned on or off depending on the status of external switches. It can be connected to doors and windows so that it stops operating when they are opened and restarts when they are closed, ensuring maximum energy savings. In addition, in emergencies, such as when the fire detection system is activated, the air conditioner can be automatically turned off, enhancing the safety of the space and the people inside.
Compatible with BMS systems
The air conditioner is fully compatible with building management systems (BMS), allowing for centralised monitoring and integrated control of its operation. Through this interface, building managers can monitor performance, energy consumption, and equipment status in real time, ensuring immediate diagnosis and faster response to any needs. At the same time, integration into a BMS contributes to energy savings, improved efficiency, and simplified overall building management.
WiFi functionality with TUYA support
The air conditioner has a built-in WiFi function with TUYA platform support, offering advanced, smart control from wherever you are. Using the dedicated Android and iOS app, you can easily adjust the temperature, change modes, or schedule the device to operate according to your needs—all with a tap on your phone or tablet screen.
Over-The-Air (OTA) technology allows for automatic software upgrades, ensuring that your device is always up to date with the latest improvements. This gives you complete control, convenience, and energy savings, with the peace of mind that comes with a modern, "smart" climate control system.
Fresh Air Intake for a Healthier Atmosphere
The Fresh Air function ensures a cleaner and more pleasant feeling in your space, providing continuous air renewal in the indoor environment. Through a specially designed hole in the indoor unit casing, the air conditioner can introduce fresh air from outside, up to 15%, significantly improving the quality of the air you breathe.
This technology helps to reduce CO₂ concentration and create a healthier, more natural atmosphere, making the space more comfortable and pleasant without sacrificing the energy efficiency of the system. It is the ideal choice for homes, offices, and professional spaces where clean and revitalized air is a priority.
Water Pump
The air duct has a built-in water pump with a maximum lift height of 1200 mm, allowing reliable drainage of condensate even when the drain point is higher or further away. This translates into easier and more flexible installation (e.g. in suspended ceilings, long drainage corridors or confined spaces), with stable flow that prevents water backflow and potential leaks.
The result is optimal drainage performance, smooth unit operation, and reduced maintenance needs — a significant addition to reliability in residential and commercial applications.
Double air intake
The unit has a dual air inlet, offering the option of suction from either the rear or the bottom. This flexibility greatly facilitates installation, adapting the device to different space requirements and ensuring optimal performance in all conditions.
Double drainage outlet
The unit has a dual drain outlet, offering the option of choosing the drain direction either to the right or to the left. This flexibility simplifies the installation process, allowing the device to be easily adapted to the requirements and specificities of each space.
Extremely slim design
The extremely slim design of the air duct units, with a new body thickness of just 200 mm, allows for easy and discreet concealed installation. The reduced dimensions save valuable space during installation and facilitate the harmonious integration of the unit into different architectural and decorative environments.
10-year warranty on the compressor and 5 years on the entire device
High-quality construction and carefully selected spare parts ensure the smooth operation of MORRIS devices for many years. The use of high-performance compressors from renowned manufacturers enhances maximum efficiency, with low energy consumption and limited noise levels.
