4) Auto swing control
The indoor units of Wall mounting and cassette series have the swing function. By this function, you can increase
the indoor air convection and the uniformity of indoor temperature regulation.
◆Reset
The swing louver will sway once automatically when electrifying for the first time. It can make the swing louver
return to the initial positions, and ensure the accuracy of swing louver action.
◆Using Indoor Units’ Own Buttons for Start
When you use the indoor units’ own buttons for start, the automatic swing will work automatically. The swing louver
will swing back and forth between the max and min positions (there are different max and min positions according
to different modes)
◆ Use the Wired Controller or Remote Controller for controlling
When using the wired controller or remote controller for start, if you don’t set the automatic swing signal when
starting, the swing louver will stop at default location (The default locations are different according to different
modes). If the automatic swing signal has been set well when starting, the automatic swing will automatically work.
The swing louver will swing back and forth between the max and min positions (there are different max and min
positions according to different modes).
Cooling / Dry / Fan mode Heating mode
When the wired controller or remote controller sends an automatic swing signal, the automatic swing function
will be started, and the swing louver begins to swing from current position.
When the wired controller or remote controller sends a stopping swing signal, the automatic swing function will
be stopped, and the swing louver stops at current position.
◆ Others
When the indoor unit receives the shutdown signal, detecting the fault signal and defrosting signal unless the
auxiliary electric heating protection, no matter the swing louver are under any state, they will all stop at initial
position after the cessation of indoor fans.
When the indoor units detected the auxiliary electric heating protection, no matter the indoor units are under
any state, the automatic swing will work, and the indoor fans will run at high speed at the same time.
5) Controlling of drainage pump motor
Cassette indoor units have drainage pump device to discharge the condensation water which is produced during
cooling or drying.
◆ When the indoor unit is operating under cooling or dry mode, the water pump and compressor will start at the
same time.
◆ When powering off or cooling stop, drying stop or transfering to other modes, the water pump will be powered
off after five miuntes.
◆When water level is flooded for 8 second at any mode (include power-off), the water pump must be started at
once. The pump will not stop running untill the flooding signal disappears and it will stop running ten minutes after
