Comfort & Convenience

Dry Operation

Reduces humidity by removing moisture from the air without effecting indoor temperature.

Hi Power Operation

Provides 15mins of boosted power to quickly heat or cool your home before returning to normal operation. Perfect for when you first turn on it the unit. Note: For FDE, FDT, FDTC, FDUA, and FDUM series can only be enabled using the RC-EX3 wired controller.

Silent Operation

Set periods of time where the unit will operate with reduced noise levels, perfect for night time and an uninterrupted sleep.

Night Setback

Designed for the colder seasons, this function ensures the room temperature is kept at around 10˚C, even while unoccupied.

On/Off Timer

Set your unit to turn on and off once, at specific times, within a 24 hour period. Unit will then turn on and off at the specified times every day.

Microcomputer-Operated Defrosting

Automatically activated during low ambient temperatures to prevent the frosting of the outdoor heat exchanger.


In the unlikely event of a fault the internal microcomputer automatically runs a diagnostic of the system. This enables a service agent to quickly isolate and repair any issues.

Auto Restart Function

If there is a temporary loss of power, when power is restored, the unit will automatically restart in the same operating mode it was in.
