Early models: In the early 1970s, the first multi-line products appeared. This product requires each indoor unit to be equipped with an independent outdoor unit, which causes inconvenience in terms of installation, maintenance and cost.
Basic multi-connected system: It consists of one outdoor unit and two or more indoor units, and each indoor unit can control the temperature independently.
Standard Edition Multi-connection Solution
Suitable for general home or office. The solution includes one outdoor unit and two to eight indoor units, which can be combined according to user needs. Each indoor unit can independently control the temperature and wind speed, and can set the timer switch and sleep mode. This solution adopts ordinary frequency conversion technology, which has good cooling and heating effects, and can meet the daily needs of most people.
case:
A family of three in a community lives in an apartment with two bedrooms and one living room. They choose the standard multi-connection solution with one outdoor unit and two indoor units. Indoor units are installed in the living room and master bedroom to meet their daily needs. Customers can control the temperature and wind speed through the remote control or mobile APP.
