3.2 Normal Operating Parameters of Refrigerant System
Under the following conditions, the operating parameters given in Tables 6-3.4 and 6-3.5 should be observed:
 The master outdoor unit can detect all the indoor units.
 The number of indoor units displayed on DSP2 is steady and is equal to the actual number of indoor units installed.
 All stop valves are open and all indoor unit EXVs are connected to their unit's PCB.
 If the combination ratio is 100% or less, all the indoor units are currently running and if the combination ratio is more
than 100%, indoor units with total capacity equal to the total capacity of the outdoor units are currently running.
 If the outdoor ambient temperature is high, the system is being run in cooling mode with the following settings:
temperature 17°C; fan speed high.
 If the outdoor ambient temperature is low, the system is being run in heating mode with the following settings:
temperature 30°C; fan speed high.
 The system has been running normally for more than 30 minutes.
