B. Ultra frequency conversion technology
Based on the principle of proportional relationship between motor speed and input frequency of working power supply: n =60f(1-s)/p and changing motor speed by changing working power frequency of the motor, it adopts AC-DC-AC power conversiontechnology, relying on our powerful control system with PWM generation ability, integrate V/F, vector control (VC) and direct torque control (DTC) to achieve control method of variable frequency PID calculus, mainly drive variable frequency by way of PWM synthesis drive, fully integrate power, electronics, microcomputer control and other technologies.
C. Advanced Carel Operate System, ultra intelligent

Especially superior heat dissipation circuit board design, longer service, over 3 time of other brand's, simple click and fully play the characteristics of DC inverter frequency conversion system to achieve overlocking performance.
D. Multi-speed mute fan motor
ROHS fan blades, ultra-low noise, durable & reliable, constant max air flow to satisfy heat supply.
E.Soft-start and soft-shutdown
Protecting both electrical system and all key parts, such a EEV, SANHUA 4-way valve, LG AC contactor & other World famous brand components ensure heat pump device 2-3 time longer service by
1) making output torque of the motor meeting the requirements of mechanical system for starting torque, ensuring smoothacceleration & smooth transition, and avoiding destructive torque impact;
2) achieving both starting current meeting the requirements of motor's bearing capacity, and the insulation damage or burnout caused when it starts.
3) reducing both voltage sag range and the content of high-order harmonics etc.
F. High-tech shock-absorption all copper construction piping
High-accurate completely automatic silver welding, easy maintenance.
G. High-density protective jacket for minimum heat lost
Aviation class insulation foam with outstanding sound absorption.
H. Classic European outlook forming
Fashion taste, never out of time.
I.Portable compact design
Saving room for installation & operation.
J.Fast heating and cooling speed
Before the indoor temperature reaches the set value, the Panasonic rotary compressor delivers high levels of efficiency, enabling the unit to operate at high frequency so that it can heat water or provide house heating/cooling at a faster speed.
