Technology
Aluminium heat exchanger with hydrophilic coating
Improved wettability of the heat exchanger aluminum plates which have a special coating with a hydrophilic layer, ensuring rapid removal of condensate from the indoor unit that does not allow to quickly form of mold and bacteria, providing a more efficient operation of the air conditioner.
Central Controller
- The central controller is used for centralized management of indoor units (up to 64 indoor units can be connected via an adapter card).
- The indoor units can be divided into 20 zones, each zone can contain no more than 64 indoor units. All indoor units in one zone can only be set to the same mode. (By default, "the zone is not assigned to indoor units").
- Users can select the desired mode and temperature with a weekly schedule.
Dry Mode
Dry mode automatically selects cooling, based on the difference between fixed and temparaturoy actual room temperature. The temperature is regulated while reducing humidity repeated switching on and off of the cooling and ventilation only. when the dry mode on the remote control shows "Drop"
Multi-Bend Heat Exchanger
Increased heat. This unit uses the heat exchangers with tubes of a special design, the inner surface of which has trapezoidal notches "Innergrove cooper", which provides maximum heat transfer surface area increased. Due to this heat increases by 28%, reduced power consumption, and hence increases the efficiency of the system.
Turbo
Tthe «Turbo» function - when you turn on this mode, air conditioning provides the most rapid cooling or heating, to create comfortable conditions in the shortest possible time.
Description
- Multi-refrigerant outlet pipe method: left\right\rear, more flexible for installation
- Longer the connection pipe, Gas pipe: 468mm/Liquid pipe: 550mm, more flexible for the installation.
- Adopts new type fixing plate, easy for installation and stable.
- The EXV is built-in the indoor unit, compact size, and convenient for the installation.
- The Panel assembly of S type indoor unit can be exchanged with C type indoor unit, alternative panel.
- Reserved the socket on main control board for water pump and PCB can be customized if you need water pump function.
