Normal Operating Parameters of Refrigerant System
Under the following conditions, the operating parameters given in Tables 5-5.4 and 5-5.5 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.
