REMOTE CONTROL-KEY NAMES & FUNCTIONS
Once the U-TOUCH stars appear, the remote will send a signal of the remote-local temperature to the indoor unit,
and this remote-local temperature will supersede the return air temperature as the unit's target temperature.
Every 10 minutes such signal will be sent from the remote to the indoor unit updating the remote-local
temperature. If at any time during this process no signal is received by the indoor unit from the remote, the unit
will switch back to the previously set temperature before the U-TOUCH feature is activated. To turn the U-
TOUCH feature off, simply press the U-TOUCH button until you see the symbol disappear from the remote
screen. By doing so, the return air temperature will take the place of remote-local temperature as the unit's target
temperature. U-TOUCH is what YOU WANT. U-TOUCH feature brings to you a true comfort level wherever and
whenever you want.
"SWING" BUTTON: Hold the swing button (symbol
shown above) for more than 2 seconds and the
indoor air louver will start to swing between the
highest and lowest limits. Once the swing button is
released the louver will stay in the last position where
the button was released.
If the swing button is pushed just once the swing icon
will appear on the remote and the louver will swing
up and down continuously between the highest and
lowest points. Push the swing button once more and
the icon will disappear on the remote and the louver
will remain at the last point the button was pushed.
When the unit is powered off by the remote the louver
will close on the indoor unit.
Press this button to set up the desired swing angle
which circularly changes as below. (Insert swing
picture)
"U-TOUCH" BUTTON: Since the indoor unit is normally mounted high up on the wall or attached to the ceiling, the
temperature at where the return air sensor is installed inside the indoor unit is higher than what it is where the
area people stand and can feel (4 to 7 feet above the floor). If the unit uses the return air temperature as its
target control, people may feel colder than what they really want (target) in both cooling mode and heating mode.
The facts of air stratification and warm air rising and cold air dropping requires users to set up, by experiments or
experience, the target temperature quite a few degrees higher than what you really want , in order to reach a
satisfied or more precise indoor comfort. This is a common drawback of AC/HP units made by other manufacturers.
With YMGI's U-touch feature, this can be avoided and your comfort level can be improved.
When you press the U-TOUCH button on the remote control, the unit will use the temperature where the remote
is located as its target temperature control. Once you do so, you will notice a figure of a person surrounded by
stars appear on the remote.
"SWING UP AND DOWN" BUTTON
Press this button, to set up swing angle,
circularly changes as below:

ABOUT BETWEEN INDOOR UNITS
If any two indoor units are controlled to run the following modes, indoor unit will run into mode clash or
conflict. All indoor units will stop to run and show Protection/Error code E7, unless shut-off and then
re-power:
Some on HEAT Mode, while others on COOL Mode and/or DRY(Dehumidify) Mode and/or FAN Mode.
NOTE:
