The control instruction is sent to the indoor units registered in the automatic 
cooling/heating switch group when the control implementation conditions shown on 
the previous page are satisfied. The actual control instructions sent differ according to 
the control method setting (fixed air conditioner/operating air conditioner 
selection/average) and the satisfied conditions (switch from cooling to heating, etc.). 
The control instructions for each situation are shown below.

<Instructions sent to indoor units when control is implemented>

1.Fixed air conditioner/operating air conditioner selection methods

   The control instructions are determined by the operation mode of the main indoor  
   unit and the main set temperature. Instructions regarding the operation mode and 
   the set temperature, shown below, are sent to all the indoor units registered in the 
   group once all the control implementation conditions on the previous page are 
   satisfied.

   For this control, when the operation mode of the main indoor unit is automatic, 
   whether it is automatic cooling mode or automatic heating mode is checked when 
   judging the control conditions. Once the instructions have been determined, either a 
   cooling or a heating instruction is sent to indoor units in automatic operation mode.
   (They switch from automatic to cooling or heating.)

2. Average Method

   Unlike the fixed air conditioner and operating air conditioner selection methods, the  
   set temperature is decided based on considerations of the current set temperature 
   for each individual unit, without sending the same instruction based on the main 
   indoor unit to all the air conditioners. When implementing the control, the following 
   operation modes and set temperature instructions are executed.
