About priority room function

INFORMATION

▪ The priority room function requires initial settings to be

made  during  the  installation  of  the  unit.  Ask  the
customer  in  which  rooms  he  plans  to  use  this  function
and make the necessary settings during installation.

▪ The  priority  room  setting  is  only  applicable  for  an  air

conditioner indoor unit and only one room can be set.

The  indoor  unit  for  which  the  priority  room  setting  is  applied  takes
priority in the following cases:

Operation mode priority:

 If the priority room function is set on an

indoor unit, all other indoor units enter the standby mode.

Priority during high-power operation:

 If the indoor unit on which

the priority room function is set operates at high power, the other
indoor units will run with reduced capabilities.

Quiet  operation  priority:

  If  the  indoor  unit  on  which  the  priority

room  function  is  set  to  quiet  operation,  the  outdoor  unit  will  also
run quietly.

Ask  the  customer  in  which  rooms  he  plans  to  use  this  function  and
make  the  necessary  settings  during  installation.  Setting  it  in  the
guest rooms is convenient.
