5-2 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by:
1) the difference between the room air temperature (RAT) and the set point temperature (SPT)
2) the protection level at which the system is operating
NOTES
In addition to the temperature difference of above, the operation of the main components (CM, FMO,
FMI) is also controlled by protection function.
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).
5-3 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation. The CM, FMO and FMI are
controlled by the same parameters.
NOTES
1. After the CM has stopped, the FMI runs for 30s in order to purge heat from the indoor coil.
2. The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cold air (see COLD DRAFT PREVENTION feature for details).
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).
