6. FUNCTIONS
6-1 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM) and of the fan (FM) 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 FM is operating with the “Auto Fan Speed” setting. If the user has selected the
Low, Medium or High fan speed, the FM will run constantly at that speed only.
2. In addition to the temperature difference of above, the operations of the main components (CM, FM)
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).
