SMART GRID Function (Demand Response) (applicable models
only)
When the refrigerator operates in SMART GRID (Demand Response) mode, the Energy
Management Refrigerator function can control energy usage or delay the operation of
some functions to save money when energy prices or demand are the highest.
NOTE
• You can deactivate the SMART GRID (Demand Response) function at any time using the
Peak Demand Off function.
• To use the SMART GRID (Demand Response) function, you need a separate contract with
your electric utility company.
In addition, to use the Smart Grid (Demand Response) function, you must register for the
service with your electric company. The company must have an EMS (Energy Management
System) that supports SEP (Smart Energy prole).
Using the SMART GRID (Demand Response) Function
This feature monitors energy prices and demand information from your utility company
and sends notications to the refrigerator to run high energy consuming tasks during off-
peak times when electricity costs and demand are lower.
If the refrigerator receives a control signal from the utility company, the refrigerator will
display the DAL (L3) ~ TALR (L4) levels on the refrigerator display and control the power
consumption according to the level.
[Exception condition] The DAL and TALR control signals from a utility company work as
long as product performance is maintained.
If the refrigerator receives the SMART GRID (Demand Response) signal (DAL or TALR), the
refrigerator will operate in Delay Appliance Load (Display:L3) or Temporary Appliance Load
Reduction (Display:L4) mode.
• Delay Appliance Load (L3): The refrigerator responds to a DAL signal by providing a
moderate load reduction for the duration of the delay period. This function controls
functions that consume a lot of energy such as adjusting the Cooling system, running
the defrost cycle, and making ice.
- When the refrigerator operates in DAL (L3) mode, “L3” is displayed on the
refrigerator display.
- DAL mode is automatically deactivated after it lasts for the amount of time stipulated
by the DAL signal (max. 4.5 hours) or when the Peak Demand Off key is pressed.
• Temporary Appliance Load Reduction (L4): The refrigerator responds to a TALR signal
by aggressively reducing the load for a short time period. This function reduces energy
consumption by stopping the compressor and controlling the functions that consume a
lot of energy such as the defrost cycle and making ice.
- When the refrigerator operates in TALR (L4) mode, “L4” is displayed on the
refrigerator display.
- TALR (L4) mode is automatically deactivated after it lasts for the received duration
(max. 15 minutes), or when the Peak Demand Off key is pressed. The mode is
immediately deactivated and the refrigerator returns to the normal state when the
door is opened or closed, or the dispenser is used.
