- What is Demand Response?
Demand Response is a program run by energy suppliers to reduce the strain on the power grid when demand is high. During these times, the air conditioner will automatically adjust its power usage to help lower overall electricity demand without fully turning off. - How DR Modes Work:
These models support three levels of Demand Response:- DR Mode 1: The compressor turns off, temporarily stopping cooling or heating while the fan continues to circulate air.
- DR Mode 2: The unit continues cooling or heating but limits energy use to 50% of the typical consumption.
- DR Mode 3: The unit operates at 75% of normal energy use, providing moderate cooling or heating to balance comfort with lower energy draw.
- Indicators of DR Activation:
When a DR mode is active, the OPERATION indicator on the indoor unit blinks. This shows that the unit is actively reducing energy consumption according to the energy supplier’s demand response program. It’s important to note that these modes cannot be overridden by the remote until the DR event ends. - Benefits of Demand Response Compatibility:
- Energy Savings: By temporarily reducing power during peak hours, DR compatibility can lead to cost savings on energy bills.
- Environmental Impact: Reduced energy use during high-demand times helps lessen the environmental impact, as power plants can avoid overproducing electricity.
- Grid Stability: Participating in Demand Response helps maintain grid stability, which benefits the wider community by lowering the risk of blackouts.
