5.2 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:
▪ If the outdoor ambient temperature is high, the system is being run in normal cooling mode with the following
settings: temperature 5°C.
▪ If the outdoor ambient temperature is low, the system is being run in heating mode with the following settings:
temperature 55°C.
▪ The system has been running normally for more than 30 minutes.
