Technical specifications for indoor units
Every indoor unit in the iSERIES system has its own specific features but there are also features common to all units in the range, these are listed here below.
Dynamic Cold Draft, an active protection system preventing the emission of air that is noticeably colder than ambient temperature during heating operation and particularly during defrost stages.
Antifreeze, this protection system prevents the formation of ice on the indoor unit heat exchanger when the system is working in cooling mode and there are particular temperature and humidity conditions.
Temperature settings from +10°C to +32°C both in cooling and heating modes; the units can therefore be used for indoor low ambient temperature applications such as in cellars, server rooms and radio stations... They can also be used to maintain a minimum temperature in spaces that are unused during weekends such as offices and shops, or places that are unused during the week such as holiday homes in the mountains or at the seaside...
iFEEL function, a comparative function that ensures optimum temperature settings based on the values read at the remote control sensor, the sensor in the indoor unit and the resulting ambient temperature stratification conditions, which are always different from one room to another.
Wide range IR receiver, this receives the remote control signal even under difficult conditions. It is equipped with a noise canceller for complete immunity from interference generated by low energy consumption fluorescent bulbs.
Hardware or software addressing of units for recognition on communication bus RS485.
Remote control addressing for the management of one or more grouped indoor units, up to a maximum of four units. This function is useful where several indoor units are situated in a large space (open space offices, hotel reception rooms, restaurants, etc...), and need to be controlled either by one or several remote controls.
Five operating modes: automatic, cool, heat, dehumidify and fan.
Night Function for maximum operating economy during the night without compromising comfort.
High Power Function, when maximum power is required straight away.
Active/passive air filters: all air/air units are equipped with washable mesh filters; a titanium dioxide photocatalytic anti-bacterial filter,activated via remote control by invisible dedicated LEDs fitted indoor the unit, fully compliant with EU regulations concerning UV emissions.
Intelligent air flap control based on operating mode, which when combined with the iFEEL function offers the maximum in comfort to counter air temperature stratification effects.
Automatic fan (or manual fan) to provide maximum heat (when required) and the right amount of cool, without creating annoying cold air draughts or excessive amounts of hot air.
Timer for programming the operating times of each individual indoor unit, with weekend* and holiday* controls.
Wireless and wired universal remote control for all iSERIES indoor units, with multi-function keypad, LCD graphic display, wall mount and wired* connection.
Elegant ergonomic interface with discreet micro LEDs that can be deactivated via remote control, particularly useful for those that prefer complete darkness at night.
Protective grilles, which offer the maximum in safety in compliance with standard EN60335. This allows for installation even at low heights where children could otherwise potentially touch moving parts such as fans and motors.
Heat exchangers in high quality copper/aluminium with inorganic hydrophilic aluminium, which does not emit odours and provides top performance in heat exchange output and efficiency.
Plastic materials with high quality looks and functional properties (improved thermal stability). As green as possible thanks to the use of noble acrylics such as PMMA, pure ABS for the parts on view and recycled PS for the internal structures.
MTAF(B)I/MTA8F(B)I is a wall-mounted indoor unit with a distinctive design, ideal for modern spaces and also compatible with more conventional styles. Combines easily with many different styles and colours found in the office and at home.
MTAF(B)I/MTA8F(B)I is available in size A, and at 21 dB(A) is extremely quiet. The unit is equipped with an active photocatalytic filter, which is able to significantly reduce the bacterial load in the environment thanks to the titanium dioxide oxidation process activated by completely concealed special UV LEDs that are fully compliant with EU standards.
MTAF(B)I/MTA8F(B)I is designed to provide high energy efficiency and has one very important feature: it can be recess fitted using the dedicated wall mounting kit.
The front panel made from PMMA, a prized acrylic material, is dual coated on the back and available in satin white or carbon fibre black; the transparent border along the panel perimeter creates a bright frame that responds to colour changes in the environment.
The horizontal central strip in silver conceals the noiseless remote control signal receiver and the extremely elegant blue and white micro LEDs. These are very discreet and can also be deactivated using a function developed specifically for those that prefer complete darkness at night.
MTAF(B)I/MTA8F(B)I is also easy to install, thanks to the possibility of being able to connect the refrigerant pipes either to the horizontal compartment or to the right side; the bilateral condensation discharge pipe and the possibility of fitting the unit at below two metres in height (thanks to the protection grille), complete the flexibility of this high quality indoor unit.
Titanium Dioxide filters: This filter uses the oxidising power of Titanium Dioxide (TiO2) to destroy bacteria and inhibit viruses. It also effectively reduces dust and dirt particles and helps to prevent unpleasant odours.
