Automatic static pressure control (E.S.P.)
The user can set the external static pressure (E.S.P.) by adjusting the E.S.P. button on the wired controller. The indoor unit will control the fan speed to ensure the airflow at each different rate. In addition, the user can adjust the desired static pressure by calculating the airflow and pressure loss on the duct, then set it on the remote cord.
Operation range
The new advanced technology of M.H.I. extends the spectrum of heating and cooling systems.
It helps the device work in outdoor temperatures as low as -15 °C / -20 °C during heating and-15 °C during cooling operations.
Micro Inverter technology for optimal power saving
Noise reduction
The FDU200VG operates more smoothly, with low noise, compared to previous models.
Improved maintenance space
Fan blades and motor can be removed from the right side of the indoor unit. So maintenance can be done quickly from the right or bottom side of the machine.
Convenient installation
The indoor unit is completely hidden on the ceiling, which is very suitable for decorative interior spaces.
Efficiency is improved when using a high-efficiency D.C. fan motor and heat exchanger.
Transparent inspection window
When the drain trough is dirty, the user can check it quickly through this transparent window without removing the gutter.
Control system (optional)

Conditional Measured Parameters (IOS-T1)
Cooling: Room temperature 27˚CDB, 19˚CWB, and outdoor temperature. of 35˚CDB. Heating: Room temperature 20˚CDB and outdoor temperature 7˚CDB, 6˚CWB.
* Indicators obtained in the laboratory. During operation, these stats will change higher due to ambient conditions
** Static pressure can be changed by setting on the controller. The maximum static pressure is set to “High static pressure.” The noise level value will be higher than 5dB(A) when the static pressure level is outside 200Pa
*** If a cooling operation occurs when the outdoor temperature is -5oC or below, the outdoor unit must be installed in a place that is not affected by natural wind. If the wind blows, the low pressure will drop, and the compressor frequency will increase, which reduces capacity and can cause damage to the machine.
