Daikin FCA71AV16 Installation Manual page 48

• When doing trial operation, it may take about 1 minute until the compressor begins to function, but this is not abnormal.
• When using the system the first time after installation, even if heating operation is selected, cooling operation will take place
for about 3 to 5 minutes.
Thereafter, it will change to heating operation, but this is not abnormal.
(In this case, the remote controller display will continue to display
"heating operation.") This is in order to detect if someone has forgotten
to open the stop valve during trial operation.
• If the outside air temperature is about 24˚C or more, even if HEATING
operation is set, the system may not operate, but this is not abnormal.
