▪ In case of cooling operation the evaporating temperature is allowed to go down
to 3°C on temporary base depending on the situation.
▪ In case of heating operation the condense temperature is allowed to go up to
49°C on temporary base depending on the situation.
▪ When the request from the indoor units becomes more moderate, the system
will eventually go to the steady state condition which is defined by the operation
method above.
