External Static Pressure(E.S.P) control

You can set External Static Pressure (E.S.P.) by method of manual setting on remote control. Indoor unit will control fan-speed to keep rated air flow volume at each fan speed setting. You can set required E.S.P. by wired remote control that calculated with the set air flow rate and pressure loss of the duct connected.

Quiet operation:45dB(A)

Thanks to use of DC fan motor, fan steps increase from two to four and quiet operation is achieved. (Sound pressure level 45dB(A) in the Lo mode).

Improvement of the serviceability

Fan unit (impeller and motor) can be pulled out from the right side of the unit. Maintenance can be available from the right side or the bottom side. (Common for FDUM22~160KXE6F & FDU45~160KXE6F)

Remote control (option)

Specifications

1. The data are measured under the following conditions(ISO-T1). Cooling: Indoor temp. of 27ºCDB, 19ºCWB, and outdoor temp. of 35ºCDB. Heating: Indoor temp. of 20ºCDB, and outdoor temp. of 7ºCDB, 6ºCWB. External static pressure of indoor unit is 72Pa.

2. Sound pressure level indicates the value in an anechoic chamber. During operation these values are somewhat higher due to ambient conditions.

*Powerful-Hi can be selected. Sound pressure level: FDU224/280 52dB(A). Air flow: FDU224/280 80m3/min.
