13.3.7 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.
