Up And Down Wind Blow Functions; Auto Button; Timing Function; Moment Timing - Gree Neo GWH09MA-A3DNA3A Installation, Service & Troubleshooting

Basic Functions - 18K & 24K 230 volt

(1) Up and down wind blow functions

When the unit is powered on, the up and down wind blow motor will turn a wind deflector anti-clockwise to Position
0 to shut down the air outlet. When the unit is switched on and wind blow function is not preset, under the heating
mode, up and down wind blades will turn clockwise to position D; and under other modes, the up and down wind
blades will turn clockwise to position L. If wind blow function is set at the same time as the unit is switched on, the
wind blades will swing between position L and D. The wind blades can be kept in seven states: position L, position A,
position B, position C, position D, swing between position L and D, stop at one position from L to D. When the unit
is turned off, the wind deflector will be closed up to position 0. Wind blow action is effective only when wind blow
commands are set and the indoor unit is running.
Note: When the wind blades are set at position L to B, position A to C, or position B to D through remote setting, the
wind deflector will swing between position L and D. L—A—B—C—D.
(2) Buzzer
When the controller is powered on, signals from a remote controller are received, or the auto button is pushed, a
buzzer will give out prompt tone.

(3) Auto button

When the button is pushed, the unit will operate in auto mode and the indoor fan will run in auto state. When the
indoor fan is running, the wind blow motor will work. When the button is pushed again, the unit will be switched off.
At the same time as the button is pushed, the whole unit will be powered on and enter into fast test mode; when the
unit is powered on and detects for continuous 20s (such time shall not be fast tested) that the auto button is pushed,
and if the unit is currently at fast test state, the unit will quit the fast test state.
(4)Sleep function
In this mode, the unit will select the suitable sleep curve to run according to the different setting temperature.

(5) Timing function

The main board integrates general timing and moment timing. Such two timing functions can be selected through a
remote controller on which different functions are arranged.
1. General timing:
Timing start: timing start can be set when the unit is off. When preset time is reached, the controller will operate in a
preset mode. Timing can be set at an interval of 0.5 hour in a scope of 0.5 - 24 hours.
Timing stop: timing stop can be set when the unit is on. When preset time is reached, the system will be turned off.
Timing can be set at an interval of 0.5 hour in a scope of 0.5 - 24 hours.

2. Moment timing

Timing start: if timing start is set when the system is at operation state, the system will continue to operate; if timing
start is set when the system is at stop, as the preset time is reached, the system will start to run in preset mode. Timing
stop: if timing stop is set when the system is at stop state, the system will keep standby; if timing stop is set when the
system is in operation, as the preset time is reached, the system will stop running.
