FEATURES

Optimum comfort year-round
To ensure that a room is never too cold or too hot, inverter technology
allows the system to detect subtle fluctuations in room temperature and
adjust automatically. Unlike conventional air conditioning units that must start
or stop the compressor repetitively, inverter units offer finely tuned operation
– such as the accurate control of room temperature – for a more comforting
airflow and far less temperature variations.
High–speed cooling & heating
Ideal and comforting performance is assured by controlling compressor
rotation according to the cooling and heat load of a room. Inverter tech-
nology promotes maximum compressor efficiency by flexibly changing
the rotation speed of it to accurately match operating requirements.
Extra energy – savings
Inverter technology makes the value of SEER and HSPF better compared to non-inverter model's value.
