Timer Function - Gree GWH18AC-D3DNA1B Service Manual

Setting the Room Temperature Set Point
Pressing the "TEMP +" and "TEMP - -" buttons will raise or lower
the temperature.
The unit will confirm signal receipt with a beep and the value of
the set temperature on the display, on the remote control, and on
the front panel, will change accordingly.
The temperature can be set between 61_F (16_C) and 86_F
(30_C).
NOTE: In Cooling mode, if the temperate selected is higher than
the room temperature, the unit will not start. The same applies for
the Heating mode if the selected temperature is lower than the
room temperature.
Selecting the Fan Speed
AUTO
The fan speed can be selected by pressing the "FAN" button.
NOTE: When the unit is on, the fan will run continuously in
cooling or heating. When in heating, there might be situations
where the fan will slow down or shut off to prevent cold blow.
Selecting the Horizontal Direction Louver Position
When the unit is turned on, the louvers default to the cooling or
heating position.
If the louver position is not providing adequate comfort due to
room layout or where people are gathered, the user has two
options:
1. Have the horizontal louvers move continuously. This is ac-
complished by pushing the "SWING" button. When this
button is pushed, the "SWING" icon will appear on the re-
mote control and the louvers will operate in a preset range
as shown in the figure below.
COOLING
2. If a stationary position other than the default position is pre-
ferred, push the "SWING" button once and allow the louver
to move to the desired position then push the "SWING"
button again.
NOTE: Always use the remote control to adjust the louver
position otherwise, abnormal operation may occur. If the
louver is manually adjusted out if its range, turn the unit off
and then on again.
Sometimes, in the heating mode, when the "SWING" button is

HEATING
pushed, the louvers will not start moving right away. This is
due to the fact that the fan will not start running until the coil
temperature is warm enough to prevent discomfort to the user
by blowing cold air.
Selecting Vertical Direction of the Louver
The vertical louvers can be adjusted manually to direct the airflow
to achieve the optimal comfort in the space.
