This is a universal remote control. If the remote control shows the following three kinds of status, then the swing 
status of main unit will be:

  

 

 
 
 

 

When the guide louver starts to swing up and down and the unit is turned off the swing of the air guide louver will 
stop at current its position. 
 

         When shown, 

indicates the guide louver swings up and down between all five positions.

 

 

"I FEEL" BUTTON: 

Since the indoor unit is normally mounted high up on a wall or attached to a ceiling, the 

temperature where the return air sensor is installed  (inside the indoor unit) is a higher temperature than occupied 
areas, check the air temperature (4 to 7 feet above the floor). If the unit uses the return air temperature as its target 
control, then the occupied areas may be colder than the target temperatures in both cooling mode and heating mode. 
The  facts  of  air  stratification  and  warm  air  rising,  and  cold  air  dropping  will  require  the  users  to  set  up,  by 
experimenting or by experience, the target temperature may be several degrees higher than what you really want, in 
order to reach a satisfied or more precise indoor comfort temperature. This is a common drawback of AC/HP units 
made  by  other  manufacturers.  With  YMGI's 

I  FEEL

  feature,  this  can  be  avoided,  and  your  comfort  level  can  be 

improved. When  you  press  the 

I  FEEL

  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. 
 
Once the 

I FEEL

 stars appear, the remote will send a signal  from the remote-local temperature to the indoor unit, 

and the remote-local temperature will supersede the return air temperature as the unit's target temperature. Every 
10 minutes a 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 

I FEEL

 feature was activated. To turn the 

I FEEL

 feature off, simply press the 

I FEEL

 button until you see the symbol disappear from the remote screen. By doing so, the return air temperature 

will  take  place  of  remote-local  temperature  as  the  unit's  target  temperature. 

I  FEEL

  is  what  YOU WANT. 

I  FEEL

 

feature brings to you a true comfort level wherever and whenever you want.
