6. FUNCTIONS
6-1 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by the difference between the room air temperature (RAT) and the set point temperature (SPT)
as shown in the graph.
NOTES
1. In this graph, the FMI is operating with the “Auto Fan Speed” setting. If the user has selected the Low,
Medium or High fan speed, the FMI will run constantly at that speed only.
2. In addition to the temperature difference of above, the operations of the main components (CM, FMO,
FMI) is also controlled by protection delays. That is: - the minimum off time of compressor is 3 minutes. -
- the minimum off time of compressor is 3 minutes. -
- the indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).
