2.1 Indoor DC Fan Motor Control Rules
2.1.1 Target Speed Setting

In SW engineering logic, 3 speeds are defined for each operation mode: Low (LOW), Medium (MED) and High
(HIGH).

Speed compensation for different speeds depends on unit installation height. Installation height depends on dip
switch setting. 4 installation heights are defined (1 normal plus 3 additional).


If set unit from Operation mode (cool/heat/dry) except Fan mode to OFF. IFAN should stop 60 seconds later.
2.1.2 Fan Motor Faults
If motor feedback signal is not received, IDU will enter ‘IFAN Motor Fault’.
2.1.3 Faults Handling

Outputs Handling:
IFAN, HE, fresh air, Ionizer and ESF will be turned OFF.
Capacity requirement calculation is stopped, and requested capacity is set to 0.
Other outputs will continue its normal function.

Fault Indication:
Fault will be reported through local and main bus communication and in diagnostics. Operate LED will blink.
