Intelligent

Defrosting

Unlike other time-determined

defrost system, YMGi on-

demand defrosting is intelligently

controlled by a YMGi programmed

microcomputer processor to ensure

the worry-free, eective heat pump

heating performance, in both mild

and cold weather. This unique ON-

DEMAND defrosting design helps

improve heating eciency, thermal

performance and your comfort

throughout the heating season.

High

Eciency

All YMGi DC Inverter systems,

with SEER up to 22SEER, which

is far exceeding the current world

standards for energy eciency,

are ETL listed in both the U.S. and

Canada. They are also certiﬁed

by and listed with AHRI and

ENERY STAR®.

U-TOUCH

Remote

With the touch of a button, the

U-TOUCH smart adaptive wireless

remote control puts the control

of room temperature right in the

palm of your hands. In fact, it’s the

most user-friendly remote control

available. While other mini split

systems most likely place their

indoor air temperature sensor

behind the grille of an indoor unit

mounted high on the wall.

UNIQUE

FEATURES

YMGi Technology

Adaptive Smart Control

The adaptive smart control fuzzy logics enables

a responsively quick and precise control over

the compressor frequency, voltages, fan speed,

valve opening sizes, and so on, to ensure precise

thermal and safe adjustment to allow delivery of

exact amount of warm or cool air needed to ensure

maximum comfort, at minimum energy consumption.

Soft Start

The compressor starts at a lower voltage and

frequency and ramps up over a period of time, which

makes a smooth and soft start. This also cuts energy

consumption of the outdoor unit by approximately

30% during start-up, compared to other regular

full-speed start-up. It also reduces the load on the

electrical circuit when more than one electrical device

is used at the same time.

Compressor Crank Case Heater

This component helps heat up the compressor when

the outdoor ambient temperature is low, so that the

compressor can have a smooth easy start, especially

when ambient temperatures go too low in extreme

cold weather.

De-Ice Base Pan Heater

This component will be actuated when the outdoor

ambient temperature goes too low and/or ice may

be built up in the base pan, in order to keep ice from

being built up to damage the unit.

Over-Current & Over-Heat

Over-Pressure Protection

Built-in protection against both over-current and

over-heat and over-pressure to ensure safe operation

and longer life of both components and unit.

Low Ambient Temperature

Heating & Cooling

When outdoor temperatures reach low ranges,

generally, both heat pump heating capacity and

eciency will drop from the standard ratings. With

the state-of-the-art new technology from YMGi,

heating and cooling with YMGi DC Inverter SOLO and

CHOIR, in low ambient temperatures, has become

better than many others. The powerful heating

ensures you enjoy a warm life, even in cold weather.

The DC Inverter technology and special control

logics has made cooling in low ambient temperature

ranges a reality.

Optimized System Design

Components are both individually and systematically

optimized to ensure SOLO and CHOIR a team

work well done, in wide ranges of applications, a

nd to deliver the right amount of comfort, right

when you need it, at both maximum comfort

and best eciency.

DC Inverter Technology - Continuously

Adjusting for Profound Performance

Unlike conventional systems that cycle between on

and o repeatedly, YMGi Symphony Series SOLO

and CHIOIR DC Inverter systems monitor room

temperature and continuously adjust compressor

speed up or down as needed to provide precise

temperature/humidity control, resulting in a highly

ecient system that provides a more constantly

comfortable environment. DC Inverter systems

achieve this by converting alternating current (AC)

to Direct Current (DC), modulating pulse width,

and then directing the inverted current back to

alternating current at the optimum frequency to

precisely generate the thermal output needed, and so

can maintain the selected room temperature within

very narrow ranges, consuming much less energy.

The incoming electrical power has a ﬁxed frequency

of 60 Hertz. By converter and inverter, the various

current frequencies and voltages can be generated to

supply the system, allowing the compressor to run

at dierent speeds.
