12.2.6 Odor Cut Control
To reduce the odor released from the unit.
o Start Condition
AUTO FAN Speed is selected during COOL or DRY operation.
During freeze prevention control and timer preliminary operation, this control is not applicable.
o Control content
Depends on compressor conditions:
1. Compressor OFF→ Compressor ON.
The indoor unit fan stops temporarily and then starts to blow at minimum airflow for 30 seconds.
2. Compressor ON→ Compressor OFF.
The indoor unit fan stops for 90 seconds and then blows at minimum airflow for 20 seconds.
12.2.7 Demand Control
When the air-conditioner connected to Demand Response Enabling Devices (DRED), the power consumption
especially during peak hours could be controlled.
Three Demand response modes (DRM) are available
o DRM1 = Compressor cut off
o DRM2 = Operate at 50% of rated input power
o DRM3 = Operate at 75% of rated input power
During DRM1, the Power Indicator blinks (3 seconds ON and 0.5 seconds OFF) to indicate the compressor cut
off status.
12.2.8 Pump down Operation by CN-S
A convenience method to activate pump down operation.
Control start condition:
o During power standby condition, short CN-S continuously between 1 second and 10 seconds.
Control stop condition:
o 480 seconds after pump down operation starts.
o CN-S is shorted again during pump down operation.
