47SMART FUNCTIONS
Smart Grid Function
When the refrigerator operates in Smart Grid mode, 
the Smart Refrigerator function can control energy 
usage or delay the operation of some functions to 
save energy during peak usage periods.
 • You can override the Smart Grid function any time 
(using the Smart Grid button or application).
 • To use the Smart Grid function, you need to register 
your appliance with your electric utility company.
Smart Grid Application Features
Smart Saving_Demand Response
You can lower energy usage based on Demand 
Response (DR) signals from the utility company. If 
the refrigerator is operating in Smart Saving mode 
according to the DR signal, you can see a pop up.
Seasonal Energy Savings
Lower energy usage based on time period.
Using the Smart Grid Function
This feature responds to notication events from your 
utility company to run high energy consuming tasks 
during off-peak periods when demand is lower. These 
notication events are known as Demand Response 
signals.
If the refrigerator receives a Demand Response 
signal from the utility company, the refrigerator will 
turn on the Grid LED on the refrigerator display and 
control its power consumption according to the signal.
The refrigerator will respond to the signals received 
from the utility company as long as product 
performance is maintained.
If the refrigerator receives a Demand Response 
signal, the refrigerator will operate in Delay Appliance 
Load (DAL) or Temporary Appliance Load Reduction 
(TALR) mode.
Delay Appliance Load (DAL)
The refrigerator responds to a DAL signal by 
providing a moderate load reduction for the duration 
of the delay period.
This mode 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 mode, the 
Grid LED is illuminated on the refrigerator display.
 • DAL mode is automatically deactivated after the 
period stipulated by the DAL signal (max. 4 hours) 
or when you override the Smart Grid function.
Temporary Appliance Load Reduction 
(TALR)
The refrigerator responds to a TALR signal by 
aggressively reducing the load for a short time 
period, typically 10 minutes. This mode reduces 
energy consumption by stopping the compressor and 
controlling the functions that consume a lot of energy 
such as the defrost cycle and fan.
 • When the refrigerator operates in TALR mode, the 
Grid LED is illuminated on the refrigerator display.
 • TALR mode is automatically deactivated after the 
received duration (max. 10 minutes), or when you 
override the Smart Grid function. The mode is 
immediately deactivated and the refrigerator returns 
to its normal state when the door is opened or 
closed, or the dispenser is used.
Override Smart Grid Mode
To ignore the Demand Response signal from the 
utility company and override the Smart Grid function, 
push the Smart Grid button while the refrigerator is 
in Smart Grid mode.
When you override the Smart Grid function, the 
refrigerator ignores the Demand Response signal 
and is no longer controlled by the utility company until 
the next Demand Response signal is sent. You can 
also override the Smart Grid function using the smart 
phone app.
