Power-Failure Memory Function; Locked Protection; Super Power Function; Health Function - Gree Neo GWH09MA-A3DNA3A Installation, Service & Troubleshooting

Basic Functions - 18K & 24K 230 volt
Timing change:
When the system is in timing mode, start and stop can be set through the On/Off button on the remote controller; or
timing time can be reset and the system will operate according to the latest setting. When the system is in operation
and both timing start and stop are set, the system will stay at currently set operation state. When preset timing stop
time is reached, the system will stop working. When the system is at stop state and both timing start and stop are set,
the system will keep at stop state. When preset timing start time is reached, the system will start operation. From then
on, the system will operate in preset mode at a preset start time and stop at a preset stop time every day. If timing stop
time is set as the same as timing start time, a stop command will be executed.
(6) Dry and mildew proof function
Dry and mildew proof function can be set in cooling and dehumidification modes.
(7) Control of indoor fan
Indoor fan can be set at four levels, super-high, high, middle and low, with a remote controller. When one level is set,
the fan will thus operate at such level. The fan can also be set at auto state.

(8) Power-failure memory function

What will be memorized includes modes, up and down wind blow, light, preset temperature, preset wind speed,
general timing (no Memory for moment timing), and Fahrenheit /Celsius degree. When the unit is powered on again
after power failure, operation continues according to memorized content. If timing is not set by the last remote control
command, the system will memorize the last remote control command and operate in the mode specified in the last
remote control command. If timing is set by the last remote control command and power failure happens before
the preset time, the system, as powered on again, will memorize the timing function set by the last remote control
command. Timing will be re-counted from the time at which the system is powered again. If timing is set by the last
remote control command and timing of start or stop is reached before power failure, the system, as powered on again,
will memorize operation state before power failure and will not perform timing action. Moment timing is out the
range of memory.

(9) Locked Protection

When starting up the fans, if the motor has run at a lower speed continuously for a period, for preventing automatic
protection of the
motor, stop running, and display the locked operation; if the machine is running at present, the code of the locked
fault---H6 of double-eight digital tubes will be displayed; if the machine is shut down at present, the information of
the locked fault will not be displayed.

(10) Super Power Function

In cooling and heating modes (automatic, dehumidifying and air-supplying modes are without strong power), press
the button of Super Power, the wind speed on the remote controller is displayed as super-high air flow, and the inner
fans are also turned to super-high air flow;

(11) Health Function

When the inner fans are running, the remote controller is set at the Health function at this time (if there is no Health
button on the remote controller, the Health On order is defaulted), then start the Health function device.
3. Fault Detection of Thermo-bulb
(1) Indoor Environment Thermo-bulb: Detect the fault of thermo-bulb at any time;
(2) Indoor Pipe Temperature Thermo-bulb: During the defrosting period, the fault of the thermo-bulb will be not
detected, which shall be detected in 5 minutes after defrosting is completed; the fault of the thermo-bulb will be
detected at other times;
(3) Protecting Treatments of Thermo-bulb
1.When the thermo-bulb is detected to be short-circuited continuously for 30 seconds: It is regarded that
the temperature detected by the thermo-bulb is over-high (or unlimited), then the whole machine will exert
corresponding safety stops according to the over-high temperature sensed by the thermo-bulb, and display
corresponding temperature safety stops and faults of the thermo-bulb simultaneously.
